Pipe & Tube — Seamless, Welded, Coiled, U-Tube
Carbon, alloy, stainless, duplex and nickel-alloy pipe and tube for oil & gas, chemical, power and heat-exchanger service — to ASTM, ASME and API standards.
We supply the full pipe and tube package: seamless (SMLS) and welded line/process pipe, coiled tubing for downhole and umbilical use, and U-tubes for heat exchangers. Materials span carbon steel, alloy steel, stainless, duplex/super-duplex and nickel alloys. We supply by OD × WT and schedule, with mill certificates and the inspection your project requires.

Process & Certification: Supplied with EN 10204 3.1 certificates and, where required, 3.2 witnessed inspection (ABS, DNV, BV, LR, SGS, TÜV). Testing includes UT, hydrostatic, PMI, flattening, flare and charpy impact.
Industries: Oil & gas (upstream/midstream) · Refineries & petrochemical · Power & boilers · Heat exchangers & condensers · Offshore & subsea · Desalination.
A: Seamless is preferred for high pressure/temperature and sour service; welded (ERW/LSAW) is economical for large diameters and non-critical duty. We help you choose per code.
A: Yes — bent U-tubes with standard or custom bend radius, stress-relieved, with eddy-current or UT as required.
A: Either; send OD × WT, quantity and length, or total metres/kg, and we return a packaged price with certificate and inspection scope.
