ASTM A53 Carbon Steel Pipe And Steel Tube

ASTM A53 Carbon Steel Pipe covers seamless, welded black and hot-dipped galvanized steel pipe。 In NPS 1/8″ to NPS 26.  A 53 is intended for pressure and mechanical applications.  And is also acceptable for ordinary uses in steam, water, gas, and air lines.

ASTM A53 Carbon Steel Pipe And Steel Tube comes in three types (F, E, S) and two grades (A, B).

A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)

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