ASTM A53 Standard Specification For Black And Hot-Dip Galvanized, Welded, And Seamless Steel Pipe

Introduction 

ASTM A53 (also known as ASME SA53 pipe) is a carbon steel alloy that can be used as structural steel or low-pressure piping, and is also suitable for general purposes in steam, water, gas and air piping. 

ASTM A53 Steel Pipe Specifications
A53 pipes are available in three types (F, E, S) and two grades (A, B).
A53 Type F is manufactured with furnace butt welds or may have continuous welds (Grade A only)
A53 Type E features resistance welding (Class A and B)
A53 S type is a seamless pipe, available in grades A and B)
A53 Grade B Seamless Pipe is our most polar product in this specification, A53 pipe is often dual certified A106 B Seamless Pipe.

Pipe ordered in accordance with this specification is suitable for mechanical and pressure applications and for general use in steam, water, natural gas and air piping. It is suitable for welding and for forming operations involving coiling, bending and flanging, subject to the following qualifications:
1. Type F is not suitable for flanging.
2. When Type S and E need to be tightly coiled or cold-bent, Grade A is the preferred grade. This provision is not intended to prohibit cold bending of Class B pipe.
3. Type E is available in non-expanding or cold-expansion types, at manufacturer's choice.

range
ASTM A53 Pipe covers seamless and welded, black and hot-dip galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous welded pipe is not suitable for flanging. The purpose of the pipe should be stated on the order.
