ASTM A53 Pipe Specification

ASTM A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. 

½” – 12” some limitations dependent upon grade. Sizes up to 26” OD are available on limited basis.

Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe.

The following types and grades of A53 pipe are covered within this specification:

• Type F Pipe – Furnace-butt-welded, continuous welded Grade A
• Type E Pipe - Electric-resistance-welded, Grades A and B, called a53 erw pipe
• Type S Pipe - Seamless, Grades A and B, called a53 seamless pipe

ASTM A53 application 

1 Architecture: maximum pipeline under more groundwater extraction when towers, boilers, hot water conveyance and so on. 
2 Machining, bearing sets, processing machinery and other accessories. 
3 Electrical class: gas distribution, water power fluid conduit. 
4 Anti-static tubes wind power plants.

Chemical requirements for A53

ASTM A53 seamless steel pipe is an American standard brand. A53-F corresponds to China's Q235 material, A53-A corresponds to China's No. 10 material, and A53-B corresponds to China's No. 20 material.

Production process:
Seamless steel pipe manufacturing process is divided into hot-rolled and cold seamless pipe.
1. Production process of hot-rolled seamless steel pipe: tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel pipe with leverage effect detected.
2. Production process of cold drawn seamless steel tubes: tube blank → heating → perforation → heading → annealing → pickling → oiling → multiple cold drawing → blank tube → heat treatment → straightening → hydraulic test → marking → storage.
