ERW API OIL AND GAS PIPE WELDED TUBE MILL

Sinoform independently developed API ERW Tube Mill with the latest FFX FF forming technology according to the internationally accepted oil and gas pipeline transportation standard API SPEC 5L&5CT ASTM,
which can produce high-grade pipe materials ie; X42 to X120, with pipe diameters from6" to 24"φ165-610mm, thickness 4-20mm, line speed max up to 30m/min
Complete line easily operated and stable running performance,also the complete tube mill line meet a high level automation.
Raw material (steel strip) → uncoiling → shearing and end welding → material accumulating → mill-forming → high-frequency welding → removing burrs outside of weld seam → medium frequency annealing → air cooling → water cooling → online ultrasonic inspection → sizing → rough straightening → flying saw cutting → roller conveying → water pressure test → ultrasonic inspection → weighing and measuring → jet coding → pipe end protection → Finished product storage
