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
