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.
