A-53 Carbon Steel Pressure Tested Pipe
ASTM A53 carbon steel tested pipe has undergone specific testing to determine whether it can be used in mechanical and pressure applications, such as low-pressure plumbing. While designed for pressure applications A53 Tested Pipe can also be used in many vapor, water, gas, or air line applications.
Grades of A-53 Carbon Steel Tested Pipe
A53 pipe comes in three types and two grades...
A53 Type F, which is longitudinally furnace butt welded or continuous welded.
A53 Type E, which is longitudinally electric resistance welded.
A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel.
ASTM A53, Type S is now an outdated specification and has been replaced by ASTM A106 specification for seamless carbon steel pipe.
