What kind of pipes (standards) could be made in ERW processes?

   ERW steel pipes are manufactured by low-frequency or high-frequency resistance "resistance". 

These are spherical pipes with longitudinal welds made from steel plates. Oil, natural gas, and other vapor-liquid materials are transported with it, and it can accommodate a range of high and low pressure needs. It currently has a crucial place in the global transportation pipe industry.

  Heat is produced as current passes over the welding area's contact surface during ERW pipe welding. The steel is heated on both edges until a connection can be formed between them. The tube blank's edges melt and push together simultaneously due to the combined pressure. We produce various types of welded pipes, such as ERW pipe, LSAW pipe, SSAW pipe, etc.

Short Description of ERW Steel Pipe:

  • Size:OD: 21.3mm ~ 660mm;WT: 1mm ~ 17.5mm; LENGTH: 0.5mtr ~ 22mtr (5.8/6/11.8/12 meters, SRL, DRL)

  • Standard & Grade:ASTM A53, Grade A/B/C,API 5L,PSL1,PSL2,GR.B/X42-X80,ASTM A795,ASTM A135

  • Ends :Square Ends/Plain Ends (straight cut, saw cut, torch cut), Beveled/Threaded Ends,Gooved Ends

  • Delivery:Within 10-30 days and depends on your order quantity

  • Payment:TT, LC , OA , D/P

  • Packing:Bundled/In Bulk, Plastic Caps Plugged, Waterproof Paper Wrapped

  • Usage:For Low Pressure Fluid Transmission, Machinery Manufacturing,Equipment Fabrication,Fire Prevention Pipe

    What kind of pipes (standards) could be made in ERW processes?

    There are a lot of pipes could be manufactured by ERW process. Here below we list for the most common standards in pipelines.

    Carbon steel pipe in ERW
    ASTM A53 Grade A and B (and Galvanized)
    ASTM A252 pile pipe
    ASTM A500 structural tubing
    ASTM A134 and ASTM A135 pipe
    EN 10219 S275, S355 pipe

    Stainless steel ERW pipe/Pipe standards and specifications
    ASTM A269 stainless pipe
    ASTM A270 sanitary tubing
    ASTM A312 Stainless pipe
    ASTM A790 ferritic/austenitic/duplex stainless pipe

    API ERW Line pipe
    API 5L B to X70 PSL1 (PSL2 shall be in HFW process)
    API 5CT J55/K55, N80 casing and tubing

    ERW steel pipe application and usage:
    ERW steel pipe used for transporting gas and liquid objects such as oil and gas, could meet the low and high pressure requirement. In recent years, with the development of ERW technology, more and more ERW steel pipe used in the oil and gas fields, automobile industry and so on.

    Advantages of ERW pipe:
    High efficiency, low cost, material saving, easy automation.
