    Q235 steel  pipe with painting, round 12 inch erw steel pipe, steel tube for buildings materials

    ERW welding round pipes also are called as Electric Resistance Welded Pipes. This  type of steel pipes and tubes are widely used in various fields such as  engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and  tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

    While manufacturing ERW steel pipes, there are some strictly standard: high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel. High performance ERW steel pipes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.

    • ERW welding steel pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved.

    • Surface finish are available in black or bare, or with protective coatings

    A53 PIPE Specifications

    A/SA53

    NPS 1/4″ – 30″

    Schedules 10 through 160, STD, XH and XXH

    ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.


    American Piping Products stocks a full range of A53 pipe (SA53 Pipe) in:

    *Grade  B

    *NPS  ¼” to 30” diameter

    *Schedules  10 through 160, STD, XH and XXH


    Scope

    ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.

    Looking for specific post-production services? See our full list.


    Materials  and Manufacture

    The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or  basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.
