ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and airlines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
Types and Grades:
A53 pipe comes in three types and two grades.
- A53 Type F, (Grade A only),
- A53 Type E, which is longitudinally electric resistance welded (Grades A and B), and
- A53 Type S
Scope
ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flagging, and other special purposes and are suitable for welding. The continuous-Welded pipe is not intended for flanging. The purpose for which pipe is intended should be stated in the order.
Application
ASTM A53 standard pipe steel ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and airlines. It is suitable for welding and suitable for forming operations involving coiling, bending, and flanging.
Materials and Manufacture
The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of the electric-resistance welded pipe in Grade B shall be heat treated after welding.
