Oil and gas line pipes

Welded steel tubes range:

— ∅ 114 - 530 mm (4½ - 20")
— Wall thickness: 1.8 - 24.0 mm (0.07-1/2")

  • Pipes are produced by high-frequency welding from carbon and low-alloy grades: up to X70
  • Pipes undergo multi-stage non-destructive testing using an eddy current flaw detector, automatic and manual ultrasonic flaw detector, mechanical and 100% hydraulic tests.
  • Pipes undergo multi-stage non-destructive testing, acceptance mechanical tests of base metal and weld and 100% hydraulic pressure test
  • Pipes fully comply with requirements of international standards
  • All pipes are supplied pre-treated: with local heat treatment of weld or bulk heat treatment
