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.
ASTM A53 is a standard specification for carbon steel pipes used in various applications.

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)
Mechanical properties of ASTM A53
ASTM A53 is suitable for a variety of forming processes, including coiling, bending, and flanging; continuous weld pipe (Type F) is not suitable for flanging.

ASTM A53 Grade B Pipe
ASTM A53 Grade B Pipe is one such carbon steel pipe grade that comes under this standard. The ASTM A53 Grade B ERW Pipe size ranges between½inches to 36 inches and the wall thickness ranges between 3mm to 12mm. A53 Gr B material can is used to weld these pipes that are available in the plain end, beveled, and threaded end.
