	<title>Axxair orbital global process</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3639</link>
	<description><![CDATA[FOR the past 15 years, Axxair has developed a global package proposal including orbital cutting, orbital beveling and orbital welding machines. It is able to respond to the highest quality standards requested by industries such as aerospace, semiconductor, pharmaceutical but also lower rated standards such as in food and beverage where the price is an important issue. With its new orbital power source SASL160, it is able to offer affordable systems starting with less than €15,000.  Such price categories allow quicker return on investment. The technical capacity was not compromised and the SASL160 offers all necessary functions such as auto programming, printing of parameters, 200 programs stored on a flash card, real parameter acquisition, and step mode welding for example. For industries such as chemical and petrochemical using thicker pipes, Axxair has launched the SASL300, which offers modularity with the full version integrating arc voltage control, oscillation control, cold wire control and efficient high capacity cooling allowing the use on tube to tube sheet production applications. Being able to respond with the widest range of orbital cutting machines from 5 to 1100mm in diameter combined with unique prefabrication machines as well as open heads and closed heads, Axxair has the capacity to manage the whole tubing process. Therefore, it says it allow higher service proposal, better training capacities and less process interferences for higher return on investment. Its patented orbital beveling system allows prepping of pipes in second – the carbide tipped J heads are the ideal solution to prepare pipes to be orbitally welded. This technical global approach would not be as efficient without a strong worldwide network of subsidiaries and partners that allows Axxair to be close to its customers in Asia and from its Korean Office, in Europe from its French headquarter, its German subsidiary and its Spanish office and in the USA through its future subsidiary in Texas. In a quickly changing environment, service has to be a top priority – service means technical innovation to provide equipment with higher productivity, offering technical advice for sorting out the most appropriate solutions, reacting quickly with a complete range of machines being available on stock and offering high level training all around the world in more than five different languages. ]]></description>

	<title>Roll forming technology from Japan</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3636</link>
	<description><![CDATA[Sanyo Seiki Co, Ltd is a forming roll maker from Japan, and is expanding its business globally under the slogan “Technology, from here to the world”. The company started to perform roll forming analysis using FEM simulation software in 2007. This shows how the forming will be carried out by each stand, and visualises various forming defects such as edge wave (which mostly occurs when forming thin-walled pipe), torsion, camber and cutting deformation for open profile. Using this method, the company can devise countermeasures without carrying out actual forming. In 2009 Sanyo Seiki received a technical development award from JSTP (Japan Society for Technology of Plasticity), with the technology of the Partial Step Forming method. This technology is a means of suppressing work-hardening very little while forming electric resistance welded pipe. In the past, pipe that needs tough secondary processing, such as automobile mufflers, had to be annealed to put off strain inside the pipe. This technology acquired a good reputation because it enabled removal of the annealing operation and achieved cost cutting. The company won a major contract from Vyksa Steel Works of Russia last year, receiving an order for fabricating 1,492 rolls, with a total material weight amounting to 1,267 tons. Fabrication started in April and finished in December. Sanyo Seiki will participate in the Tube show in Düsseldorf in March. ]]></description>

	<title>Robotic flange to tube welding cell</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3635</link>
	<description><![CDATA[WHEN Dutch company Kranendonk was asked to assist with improving the weld quality, flexibility of production, and cycle and delivery times for pipe sections it responded by implementing the world’s first robotic flange to tube welding cell.  The flange to tube cell is a robotic production system for Assembly and welding of flanges and sockets to tubes for bespoke pipe infrastructure in the offshore, shipbuilding and petrochemical industries. This innovative system consists of four simultaneously operating robots mounted on a traveling track.  Using vision technology the robots automatically position, tack and weld a wide range of flanges and sockets to tubes of any desired length.  The information, which is required for the system is loaded from the CAD-design. Since the pipes will be bended afterwards the deformation is calculated before hand. The pipe is sawed on the correct length and based on the deformation information the orientation of the bolting holes is calculated.  Two large robots pick up the flanges with special tooling. During pick-up the integrated vision system determines the position and orientation of the flange. The vision system compensates for dimensions of the tube and aligns the flange onto the tube. Two small robots tack the flanges to the clamped tube. After tacking, the tube is rotated at welding speed while all four robots simultaneously weld both flanges. After completion, the tubes are transferred to the output buffer.  The production line is operated by one operator using its full graphical operator interface. The menu structure and push buttons of the ARAC software automatically guide the operator to the right command to perform a certain task.  Combining the high accuracy, the faster delivery time and the easy control the system contributes to increase of productivity and more grip on your production process.  ]]></description>

	<title>South Africa tube and pipe market continues to grow</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3634</link>
	<description><![CDATA[SOUTH African pipe and tube manufacturers have been exporting their products for more than 40 years, and are committed to sustaining and growing this market through the provision of high-quality products, excellent service and timely delivery via established logistics and distribution networks.  In 2011, tube and pipe exports continued to grow, particularly value-added tubular products such as seamless. Value-added tubular exports largely comprise scaffolding tube, conveyor and mine appliance tube, shock absorbers (inner and outer tubes) and, since 2011, tubular steel security doors and all tubing used in automotive products.  From 2009 to 2010, total exports of tube and pipe grew by 16 per cent in volume and 19 per cent in value. Export figures for 2011 (available for the nine-month period of January to September) are showing even more impressive growth and, if calculated on an estimated annualised basis, would represent an increase of more than 30 per cent in value and 33 per cent in volume. The increase in value over this period reflects the trend of increasing exports of value-added products compared to commodity tube.  According to Colin Shaw, executive director of the Association of Steel Tube and Pipe Manufacturers of South Africa (ASTPM), the steel tube and pipe industry has recovered well from the 2008 economic recession and, overall, 2011 was a good year for the industry.  Export Council STEASA (Steel Tube Export Association of South Africa) is focusing on helping local steel pipe and tube manufacturers to increase exports, particularly value-added products, which have potential for growth in established markets.  Mr Shaw said a number of its members have invested in specialised laser- and plasma-cutting equipment to add value to tube and pipe, making it cheaper to fabricate and easier to assemble these products.  ]]></description>

	<title>Polysoude publishes TIG cladding handbook</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3633</link>
	<description><![CDATA[DURING the Industrie 2012 (Paris) and Tube and wire 2012 (Düsseldorf) trade fairs, Polysoude, an expert in TIG/plasma automated procedures, published the first handbook for ‘Mechanised TIG Cladding for Industrial Applications’. The 48-page guide contains information and an in-depth insight into the technology and know-how of this high-potential process. Industrialists will find helpful information and assistance on the subject, as well as practical tips and advice as to the various uses of TIG cladding.  Flexibility, excellent surface quality of TIG welds, and the possibility to weld in all positions are determining factors that have led Polysoude to the automation of this process in response to the growing industrial demand.  The main advantages of the TIG process are that it allows for mastery of the weld pool in all positions, achieved thanks to high flexibility in the adjustment of welding parameters; and the possibility to control and supply the required amount of energy accordingly, enabling the respect of the characteristics of the material and in the particular case of cladding, to reduce the surface dilution level using exclusively one or two successive layers.  Polysoude, with over 50 years’ experience in the field of orbital and mechanised welding, has accelerated the development of equipment and welding operating procedures for cladding operations using the TIG process and its variants. One such variant is the buttering of the ends of workpieces, for example in the case of heterogeneous joints.  Cladding operations that use the TIG process are widely used in the repair of high-value added worn parts in service or following manufacturing anomalies during machining; and preventative cladding operations using materials that are resistant to mechanical wear and tear, abrasion and corrosion.  In order to monitor the welding process, the operator can be assisted by a video system, exclusive to Polysoude. This supplementary quality guarantee consists of cameras mounted close to the torch, or even integrated in the body of the torch for more difficult cases, such as limited access or harsh/extreme environments such as preheating.  ]]></description>

	<title>Combilift Triumphs at the FLTA Awards </title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3631</link>
	<description><![CDATA[IT was a night to remember for Combilift at this year’s FLTA Awards for Excellence, held in Birmingham, UK. Not only did the company win the Innovation Category for the second time, for its new Rough Terrain RT forklift, but its Combi-CB model  also scooped the first and only “Victor Ludorum“ prize, billed by the FLTA as the ultimate winner of winners in the awards’ 18 year history.    To mark London 2012 the FLTA introduced an Olympic theme to the event, which was co-hosted by British Olympic Champion Sally Gunnell.  The Victor Ludorum was a special one-off award chosen from every winning entry in all previous awards in the Environment, Ergonomics, Safety and Innovation categories. The final votes were cast by attendees at the event, and as befits an accolade of this nature, the winner’s trophy was in a class of its own. The Archimedes (or “Archie”) statuettes awarded to winners are cast in bronze by internationally renowned sculptor Les Johnson. The gold plated Archie awarded to Combilift is unique and was created to mark the Association’s 40th year. “This very special trophy will naturally have pride of place in our awards cabinet,” said Combilift MD Martin McVicar.  Launched in 2011, the RT was originally designed in collaboration with Keyo Agricultural Services, one of the UK’s largest providers to the poultry processing sector. Whereas forklifts previously used in this application have been modified versions of mainstream models, the Combi-RT is the first purpose built, no-compromise machine designed for the exacting demands of the industry and represents a significant step forward in the handling of live poultry.  The FLTA’s verdict on the Combi-CB when it won the Innovation category in 2009 was that “the Combi-CB compact multi-directional counterbalance transfers the 4-way principle into a small counterbalance truck for the first time.” This ground- breaking development, designed for operations handling a mix of both palletised and long loads, has since become one of Combilift’s best selling models.  Sam Moffett of Combilift accepted both awards on behalf of the company. Martin McVicar comments: “Innovation and substantial investment in R&D have been our bywords since we established Combilift and we are delighted that this has once again been recognised. To have the Combi-CB acknowledged by our peers in the materials handling sector as having made ‘the most outstanding contribution to the industry since the awards began’ is the ultimate tribute. We extend our thanks to the FLTA and everyone who voted for us.”   ]]></description>

	<title>Sandvik celebrates steel production anniversary</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3630</link>
	<description><![CDATA[THIS year marks the 150th anniversary of steel production by Sandvik, and this was celebrated on the company’s stand at Tube 2012 in Düsseldorf. A central feature of the stand was a model of the Vasa, a 17th Century Swedish maritime treasure and subject of an on-going research and development collaboration between the Vasa Museum and Sandvik. This collaboration is facilitating the essential replacement of 5,000 iron bolts with highly advanced stainless steel bolts in order to preserve the structural integrity of the vessel well into the future.  Sandvik offers materials technology solutions for demanding applications in some of the most arduous environments. Its research and development capability has resulted in the introduction of the latest hyper-duplex stainless steel for demanding sub-sea applications and zirconium tubing for the nuclear industry.  In heat exchanger applications, hyper-duplex tubes significantly outlast alternatives, not only proving cost effective throughout their life cycle, but also increasing operational plant uptime. It is claimed that by replacing carbon steel tubes with Sandvik SAF 2707 HD® tubes, the rate of corrosion is reduced to one tenth. A plant using heat exchangers with the Sandvik tubes would be capable of operating for ten years without maintenance shutdowns or tube replacements.  Designed to help reduce machining requirements in component manufacture as well as reduce overall component weight, Sandvik hollow bar products were also displayed at Tube 2012, including duplex material grades. The use of this material, especially in the Sanmac form, can increase component production capability as well as cut down on waste material. A converter tool is available, as an app for iPhone and iPad, that calculates the money saved when switching from bar to hollow bar.  Sandvik’s powder metallurgy products are manufactured by the hot isostatic pressing process, which allows the production of complete geometrically intricate products that offer excellent resistance to corrosion and outstanding mechanical properties.  The company maintains a stock of popular tube material grades and sizes throughout its strategically located distribution and manufacturing centres worldwide, ensuring reliable and efficient product supply via its global distribution network.  ]]></description>

	<title>Zhejiang Kingland orders energy-efficient spiral pipe welding line</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3629</link>
	<description><![CDATA[ZHEJIANG Kingland Pipe Industry, province of Zhejiang, China, awarded PWS, an SMS Meer company, both Germany, a contract for the supply of off-line spiral pipe welding equipment.  PWS will supply an integrated system solution, consisting of a spiral pipe forming and tack-welding machine for forming and initial welding of the hot-rolled steel strip, and the three downstream off-line finishwelding stands. The new installation is to be commissioned in the second quarter of 2013.  Zhejiang Kingland will have the option of adding a fourth finishwelding stand at a later stage. This would increase annual capacity from above 180,000 tons to some 240,000 tons. Michael Stark, CEO of PWS, said: "Installation of an additional finish-welding stand was included in our engineering planning from the start, as it would permit a significant increase in production capacity, with no interruption to ongoing operation". Another highlight is the energy-efficient high-productivity welding technology available from PWS. Energy-savings are more than 30 per cent compared to older welding methods. In the new PWS technology, the welding-current sources operate without transformers, while process control is accomplished by means of a modern power electronics module. The welding machines thus attain an efficiency of over 90 per cent, and welding speed can be significantly raised with no loss of process stability.  Zhejiang Kingland will be able to produce pipes with outer diameters from 508 to 1,626mm (20" to 64") and wall thicknesses ranging from 6.35 to 25.4mm (1/4" to 1") on its new off-line spiral pipe welding machine. Pipe lengths range between 8 and 12.5m.  ]]></description>

	<title>Revolutionary pipe forming mill</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3626</link>
	<description><![CDATA[Nakata Manufacturing Company has developed a completely new forming method that can make quality pipes with lower deformation strain and has higher productivity.  The company is a general welded pipe plant supplier covering all equipment from entry section to finishing section. By making full use of a self-developed, high-speed, high-precision FEM simulator, Nakata has developed and brought many unique technologies into the industry, such as the FFX Mill and Roll Box, which apply common-use roll technology and have high formability for quality round and square pipe production. Nearly 50 sets of FFX Mill have been installed during the ten years since its development.  Nakata maintains research and development to pursue better quality pipe production. It is realised that there is a limitation in the traditional pipe forming method for a technical breakthrough.  Current pipe manufacturing methods can be classified into two basic categories. The first category is roll forming, which is widely used owing to its high productivity and low investment cost for welded tube and pipe production. However, the excessive three-dimensional deformation often gives high forming strain, high work hardening and complicated residual stress to the materials, which is the basic reason for poor product quality. In addition, the limited contact between rolls and materials not only makes the forming unstable due to weak constraint, but also brings high contact pressure, together with the unavoidable slip between the materials and rolls, which lead to bad pipe surface quality and short tool life. These problems are hard to overcome while rolls are used as the main forming tools.  The second category is press forming. Nearly plane deformation state over the product’s full length tends to give less strain and better product quality, but it also brings excessive forming load, which limits the product’s maximum length, as will as limiting productivity, and requires very costly press machinery. This method is confined to short length pipe production.  Nakata has developed a new pipe forming method named Orbital Die Forming (ODF), aimed at inheriting the advantages from both above traditional methods.  In roll forming, it is known that the larger the forming roll’s diameter is, the closer to plane deformation state the forming becomes. However, large rolls with a diameter range from several metres to dozens of metres are required to obtain this kind of ideal deformation mode, which is impossible in reality. Nakata succeeded in getting this kind of nearly ideal deformation state similar to press forming by inventing the ODF method. In this method a multiplicity of die blocks, moving in the circumferential direction on an endless track, are connected together to provide a tool surface with a very large curvature radius and work just like a huge roll.  This new forming method has both the high productivity of the roll forming method and the excellent product quality of the press forming method. Those products difficult to produce by roll forming, such as pipes with very thin wall thickness and pipes with difficult-to-form materials, can now be easily made. ODF shows great potential to meet the end user’s stricter needs, such as automobile pipes with better secondary workability and quality line pipe with higher strength and thinner wall.  At present, an ODF test mill has been built for experimental purposes, and has shown encouraging performance. The company is making it ready to be put into practical use as a new generation of pipe forming mill, and it can be expected that ODF will be on the market soon to satisfy the needs of pipe makers.  ]]></description>

	<title>Internal line-up pipe clamps</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3625</link>
	<description><![CDATA[DWT offers internal line-up pipe clamps that offer fast and accurate adjustment, no tag weld is needed, avoid oval pipe problem, can be used for pipes with different wall-thickness and offer a precise axial adjustment.  The welding quality in pipeline construction is crucial and has to fullfil worldwide standards, certified by international authorities. Companies like Norske Veritas have set up guidelines, to avoid defects and therefore environment and health risks, by use of the best pipeline equipment. Very important is the choice of the correct internal line-up pipe clamp for weld preparation, to compensate tolerances of pipe manufacturers and to avoid edge misalignment during welding process. Internal line-up clamps are the most frequently used alignment equipment nowadays, because it provides a full access to the weld seam during the entire welding process.  Benedits of using a hydraulic instead of pneumatic clamping system include:  feet have not to be adjusted to each ID; bigger range of clamping; no icing problem caused by compressed air; lower weight; reduce maintenance; no high pressure compressor necessary; and no time limitation by air tank.  ]]></description>

	<title>Machining of OCTG equipment</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3624</link>
	<description><![CDATA[ESTIMATES of the world’s oil and gas reserves vary, but what is certain is that huge investments will continue to be made in response to the challenge of increasing the yield from existing and future oil and gas fields. The inevitable consequence of the boom in exploration world-wide is increased demand for the specialised equipment used in the drilling of new wells and the extraction of oil and gas. This in turn places new demands on the capabilities of the oil and gas industry’s supply chain.  Over the past decade Danobat has emerged as one of the major suppliers of individual machine tools and complete turnkey lines to equipment manufacturers in the OCTG (oil country tubular goods) segment of the oil and gas industry. Customers for Danobat's products include Tenaris, Vallourec, Gazpromtrubinvest and TPCO, some of the most important OCTG manufacturers world-wide.  For anyone involved in the machining of difficult-to-machine materials such as high specification corrosion resistant alloys, the last thing they need is a problem with a finish machining operation that could result in damage to a high value component and delays in meeting delivery dates. The challenge that Danobat has succeeded in meeting is the design and development of machine tools and systems capable of dealing with increasing pipe thicknesses; tougher, more corrosion-resistant materials; and the demand for greater type of threads for pipe ends and couplings, all prompted by the fact that drilling is reaching deeper and deeper beneath the earth’s surface.  Danobat machine tool technology embraces the machining and threading of pipe ends and complete machining of the couplings that join pipe lengths together.  One of Danobat's specific areas of OCTG expertise is sawing technology for drill pipes, a process that involves two Danobat CP sawing machines that move along a slide in order to adjust the pipe length as required. Powerful software optimises the machining process, integrating adaptive intelligent cutting and blade deflection control to adjust automatically blade speed and downfeed for optimum performance, straightness of cut, and maximum possible blade life.  Once cut to length individual pipes, they can be thread to API, GOST or premium standards by rotating the pipe in Danobat TT and TT-B horizontal lathes. These machines are designed on a modular basis using Finite Element Analysis, with the five models in the TT range covering pipe diameters up to 20”. The main features of these lathes, which offer the choice of headstock on either the left or right side, are four-axis simultaneous thread cutting and spindle motor power up to 170kW depending on the model. With rotating pipe and stationary tools technology as the defining feature, the TT is an extremely rigid machine that provides optimum chip removal during turning and threading operations. Different designs of pipe feeding tables can be integrated into a single-source turnkey solution.  Joining lengths of pipe together requires a coupling, which again can be machined by way of a fully automated process line with the cutting process followed by OD and ID simultaneous machining performed on a Danobat TCL four-axis lathe. The machining line includes a Danobat threading lathe for producing internal Premium standard threads – the CL model requiring two set-ups while the CIH model can compete threading operations in a single clamping. When higher productivity is required, twin versions of machines are also available, providing maximum output with automatic loading-unloading systems.  ]]></description>

	<title>New equipment for hot rolling OD finishing</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3623</link>
	<description><![CDATA[MARKET trends in pipe production are swinging towards smaller and smaller production batches with a move towards production of hundreds of tonnes instead of thousands. Requests for very high production mixes, however, remain unvaried.  Danieli’s policy has always followed the principle that requests from end users are for smarter, more sophisticated and more flexible solutions. Studies are geared towards offering clients innovative plant arrangements and equipment technologies, which are easy to use but also aimed at reducing production costs and time.  Flexibility is one of the driving forces in its design department. This is not, however, Daniel Centro Tube’s only target in project development.  The New FRT (four roll technology) design philosophy aims for “total quality”. This concept gives rigid rules about the way to lead a project.  The finest results in total quality are only attainable by focalising attention on first-class products and processes. Final product quality is channelled through the entire flow of the mill and plant, therefore particular emphasis to detail and design is placed on each single piece of equipment provided by Danieli to customers.  Danieli is renowned world wide for the supply of impeccable plant design. FRT is one of the best examples of Danieli philosophy and is indicative of the important synergy taking place behind the scenes in the various departments involved to arrive at the supply of smart design while no focus is taken away from quality.  Equipment functioning is both simple and effective. In the past outside diameter finishing of rolled materials using Two and three roll technologies tended to spread out onto the roll groove, instead with FRT (four roll technology) the natural trend of the material is to collapse inwards, thus allowing to achieve a reduction in the outside diameter.  On the one hand, a higher reduction in OD per stand may be achieved and on the other, higher stretches among stands.  Wall thickness variation produced while reducing the diameter is more predictable and therefore easier to control. Uniform wall thickness distribution across the axis offers improved green pipe wall thickness tolerance. Internal polygonalisation for both two and three roll technology require oval pass designs with high energy consumption. Power absorption is essentially due to natural reduction energy and ovalisation energy.  The four roll technology (FRT) process requires less Ovalisation Energy, since pass design focuses on the production of a perfect circle. Consequently deformation energy is used to offer higher deformation efficiency.  Final results are achieved almost at the very first stand with this new pass design since outside diameter tolerances are reduced. Uniform peripheral speed and therefore a reduction in speed differences between side and bottom gorge areas means roll wear is decreased significantly.  ]]></description>

	<title>Honing machines delivered to Singapore</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3622</link>
	<description><![CDATA[THE first of two new 10m stroke 30Kw horizontal honing machines has been delivered and installed by Apperley Honing to a client in Singapore.  With over 45 years’ knowledge of the subcontract market, Apperley has used its experience to create a brand new design of hone. Called the Tubehone, the 24m-long, all-electric machines have two powerful 15kW motors driving the rotation and stroking axis. Controlled by an easy to program Siemens touch screen HMI, set up can be achieved in a matter of minutes and novice operators can be trained to run the machines in less than a day.  The Tubehones are equipped with traditional V blocks and ratchet clamps to support the workpieces as well as a unique feed-in device that allows the operator to inch the hone head in and out of the tubes in complete safety. To improve safety even further, the Tubehones’ drive shafts are totally enclosed, and whenever the access doors are open during set-up phase, the machine is restricted to slow, safe jog speeds. Only when the doors are closed can the full capacity of 32m/min and 220 rpm be achieved.  The Tubehone can be designed to suit the needs of the customer, with a range of power options from 5.5 to 30kW and workpiece lengths from 2m to 10m. The modular design means that a customer can start with a 2m machine and then acquire additional frame sections as they are needed in order to increase the capacity up to the maximum of 10m. The machines can be tailored to suit different applications, coping with small 25mm diameters bores as well as large components with 750mm outside diameters.  Managing director Charles Sanders explained, “We work with pretty much every type of honing machine here in Cheltenham. Our sub-contract department operates over 25 different types of honing machine and delivers results for clients in the automotive, defence, pharmaceutical, aerospace and petrochemical industries. We maintain, repair and refurbish honing machines day in and day out, and so, for us, it’s been a relatively small step to create and manufacture our own design.”  The two heavyweight machines were both designed and built at the Apperley Honing factory in Cheltenham, UK, and each was equipped with Apperley’s Ranger and Shell tooling.  ]]></description>

	<title>Simulation module facilitates correction of bending machines</title>
	<link>http://www.tubeandpipetechnology.com/newsdetail.php?ID=3621</link>
	<description><![CDATA[With the launch of the new software version 4.7, AICON’s optical tube measuring system TubeInspect will be extended by a practical function: now the operator has the possibility to simulate the bending process considering individual correction values, and to verify their effect on accuracy to gauge by means of a virtual gauge check.  With the help of high resolution digital cameras, TubeInspect determines the tube geometry within seconds, and thus proves accuracy to gauge. The system shows in detail which bending points deviate from the desired values, and suggests correction values. These correction values can be transmitted directly to the bending machine – TubeInspect allows the connection to up to 100 benders.  Sometimes, the correction values suggested by TubeInspect cannot be transferred one-to-one, for example if they lead to collisions at the bending machine or if corrections are suggested at parts which cannot be affected because of solid bending tools. This is where the new simulation module comes into play: when TubeInspect evaluates a measured tube as a bad part and suggests correction values, the operator can adapt them at his own discretion – after all, only he knows the actual circumstances and characteristics of his bending machine. By doing so, the operator does not take any risk because TubeInspect simulates the results of the changes and shows with a virtual gauge check if the bending process could actually produce a good part. When the right settings are found, another real bending test will take place. Therefore, in future, fewer bending tests will be necessary, which makes the setup process even leaner.  ]]></description>
