BASIC INFO

Oil and gas line pipe is made with diameters from 114 to 530mm (4. – 20”) and wall thicknesses from 4.0 to 12.7mm (0.16-0.5”). Pipes are produced by high-frequency welding from carbon and low-alloy grades: up to X70. During production pipes undergo multi-stage non-destructive testing, acceptance mechanical tests of base metal and weld and 100% hydraulic pressure test.

All pipes are supplied pre-treated: with local heat treatment of weld or bulk heat treatment. Pipes undergo multi-stage non-destructive testing using an eddy current flaw detector, automatic and manual ultrasonic flaw detector, mechanical and 100% hydraulic tests.
