ASTM A53 is standard specification for pipes, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe.

This specification covers the following types and grades:

  1 Type F-Furnace-butt-welded, continuous welded Grade A.
  2 Type E-Electric-resistance-welded, Grades A and B,
  3 Type S-Seamless, Grades A and B.

Note:
Type F is not intended for flanging.
If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe.
Type E is furnished either non expanded or cold expanded at the option of the manufacturer.

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.
