Application:

For mechanical and pressure use, and also for transporting steam, water, gas and etc.

Mill test certificates will be issued according to EN10204/3.1B
Steel grade: ASTM A53 Grade.A; Grade.B .

Packing:

Bare packing/bundle packing/crate packing/wooden protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.
Both ends of each tube will indicate the order no., heat no., dimensions, weight and bundles or as requested.

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 suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

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.
Applications: heat exchangers, condensers, heat transfer equipment and similar pipes.

Note:
DN — Nominal Diameter
NPS —Nominal Pipe Size

A53 Grade B Seamless steel pipe is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

  • A53 pipe comes in three types (F, E, S) and two grades (A, B).
  • A53 Type E has an electric resistance weld (Grades A and B)
  • A53 Type S is a seamless pipe and found in Grades A and B)
  • A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
