    Difference between ms pipe and erw pipe?

    • admin berkata:

      MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (paip hitam) is made of malleable steel.

  3. Alfredkal berkata:

    How to identify seamless steel pipe and Erw welded pipe??

    • admin berkata:

      Paip ERW keluli:You can see the weld straight down the length of the pipe.
      Paip keluli yang lancar : You can’t see the welded straight lengthon the steel pipe

      • admin berkata:

        If it is ASTM A53, Type S means seamless.
        Type F is furnace but welded,
        Type E is Electrical resist welded.
        To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the steel pipe.

        • admin berkata:

          Put H2So4 or HNo3 acid on the edges.
          It is only possible when the pipe ends are open. You can do a Macro-test.
          If it is welded, it will show the weld boundries. If not welded it will not show edges.

    what is the Process erw pipe?

    • admin berkata:

      Process erw pipe is specially designed for particular applications to ensure that it will meet health and safety standards, in addition to suiting the needs of a given manufacturing process.
      Process erw pipe is the system of pipes transport process fluids, such as industrial gases, fuels or water, around an industrial facility involved in the manufacture of products or the generation of power.

  5. Binanceorem berkata:

    Is this the erw steel pipe low carbon steel or high carbon steel ?

  6. ScottKag berkata:

    What is api for short?

    • admin berkata:

      API American Petroleum Institute standard –API (American Petroleum Institute) abbreviation.
      While manufacturing ERW steel pipes, only high-quality, continuous-cast, sepenuhnya dibunuh, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.

  7. Eluddilt berkata:

    Is there an oil casing made of welded ERW pipe?

    • admin berkata:

      Ya, sudah tentu.
      My Company is Quality Seamless Casing Pipe manufacturers & exporter. ABTER STEEL SALES Hot Rolled Seamless Casing Pipe NonAlloy API 5CT K55 J55 N80 For Oil / Gas Drilling from China manufacturer.

  8. RubenClido berkata:

    What is the erw production process?

    • admin berkata:

      The first process of producing Erw Tube is hoop slitting hot coil in a fixed width. selepas kimpalan & removing bead through forming roll,the form of Erw Tube is sized at the sizing roll within the common difference,cut with lighteousness foot,going through roughing tube inspection and having degree of straight collected at straightner.The end section of tube goes through water pressure testing for correcting the pressure according to the size after being faced plain or bevel to its use.

  9. Zafar-Islamov-an berkata:

    Structurals and Standard Pipe : TMK produces hot finished structural hollow sections of non-alloy and fine grain steel according to the standard DIN EN 10210-1,2 and cold-formed seamless and welded carbon steel structural tubing in rounds in accordance with ASTM A500.
