Standard: ASTM A53
ASTM A53 Standard specification covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding.
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 electric-resistance welded pipe in Grade B shall be heat treated after welding.A53 pipe comes in three types and two grades
- A53 Type F, which is longitudinally furnace butt welded or continuous welded (Grade A only)
- A53 Type E, which is longitudinally electric resistance welded (Grades A and B)
- A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel (Grades A and B). ASTM A53, Type S is now currently an outdated specification and has been replaced by ASTM A106 specification for seamless carbon steel pipe.
