Straightening line for US tube customer

Echomac 6/6A ultrasonic equipment for weld inspection, flaw detection and thickness and dimensional measurement

straightening line suitable to process tubes of up to 330mm diameter with 30mm wall thickness and 1,250N/mm 2 yield strength for a customer in the USA. These tubes are employed by the end user for purposes where high quality and resistance are vital. The straightening process is carried out with a machine equipped with five pairs of rollers, with each pair composed of two opposite rollers that are adjustable in height and angle. These rollers, placed in rotation and following a specific path, will force the tube to undergo a combination

of bending and crushing during the rotation and transit. To deform a tube of similar characteristics it is necessary to employ rollers of 1.5 tons with drive power up to 750kW. The machine is composed of two welded and machined main structures, one upper and one lower, connected by columns in order to obtain one rigid structure that can easily be disassembled for transportation.

MAIR Research has its headquarters and production site at Schio, near Vicenza, Italy, and specialises in the design and manufacture of tube and bar finishing equipment and integrated lines. Over the last 40 years the company has been commissioned to produce a large number of lines for companies in the steel and tube industry. Within its sites the entire production cycle takes place for all of its equipment, including design, fabrication, assembly and testing in the presence of customers prior to dispatch. Mair Research has designed and installed a

Full penetration welding technology K-TIG is a welding technology company based in South Australia. The company claims that its new high speed, full penetration GTAW welding technology has productivity, cost and quality advantages over existing processes, particularly in stainless steels and other corrosion-resistant materials. corrosion-resistant materials and super alloys, and up to 16mm ( 5 / 8 ") in titanium, zirconium and other reactive metals. The process requires no edge bevelling and no wire (although wire can easily be added). It uses as little as ten per cent of the gas normally required, and produces repeatable, X-ray quality welds.

the joint between the two surfaces to be welded. It provides high stability and operates over a wide range of welding currents and travel speeds. It was developed by the Australian Government’s Commonwealth Scien- tific & Industrial Research Organisation (CSIRO).

K-TIG welds are performed in a single, full penetration pass up to 13mm (½") in stainless, duplex, super duplex, Hastelloy, Inconel, Nimonic and other
