ASTM A53 is a carbon steel alloy, which can be used as structural steel or for low-pressure pipelines.

ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending and flanging, A53 carbon steel pipe is suitable for welding. The grades denote certain chemical and mechanical properties and should be noted in selection. A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines, Low pressure systems, Structural applications, Mechanical components, Bollards, Casing, generator plants, refineries, compressor stations, natural gas transmission, and steam conduction.

A53 pipe 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)
