General Purpose pipe

Back to list Send request

Water and gas pipes with small diameters from 12.7 to 133 mm (0,5—10,6”) are produced from carbon steel grades S185, S195T, S235JRH, P195TR1, P235TR1 (and other). Pipes are produced by high-frequency welding with induction current lead.
Pipes are subjected to hydraulic and mechanical tests. Welds undergo non-destructive testing. Square and rectangular section pipes are shaped from round electric-welded pipes on the line of the electric welding mill. At the consumer’s request pipes are packed in hexagonal and box bundles. Pipe bundles are provided with removable shipping straps for fixing in trans-shipment points and storage without additional pulling appliances.
