In the first stage of the process, the raw material is formed into a pipe body and provisionally welded at high speeds (up to 12m/min). In the second stage, the pipes are finally welded on separate stands where the inside and outside seams are welded simultaneously by means of submerged-arc multi wire welding.

› YXRAY manufactures radioscopic and radiographic X-ray testing systems

The company introduced what is believed to be the first digital radioscopic pipe testing system RTS 13.1 onto the German/ European NDT market in 2004, and offers a wide range of digital flat panel detector and image intensifier solutions. Digital radioscopic pipe testing solutions offer a number of advantages over ordinary radiographic or radioscopic testing systems. These include high-speed quality testing, digital 12-bit/16-bit X-ray images with high grey-level value, and a test procedure without the use of expensive X-ray films and chemicals.

With complete plants and individual machines, the company offers quality assurance, high quality raw materials and advanced production technology. The delivery programme of W + K comprises equipment for pipe diameters up to 64" OD for line pipes (API spec 5 L), and up to 100" OD for water pipes (AWWA C 200 spec).
