ASTM A53
Type S Seamless Pipe
ASTM A53 / ASME SA-53 Type S seamless carbon steel pipe in Grades A and B for pressure and mechanical service, available dual certified.
ASTM A53 seamless pipe
OVERVIEW
General-purpose carbon steel pipe.
ASTM A53 covers black and hot-dipped galvanized steel pipe in three types: furnace-butt welded (Type F), electric-resistance welded (Type E) and seamless (Type S). It is the general-purpose specification for steam, water, gas and air lines and for mechanical uses.
Global Seamless supplies Type S only, in Grades A and B, dual certified to ASME SA-53 where the order requires. Pipe is hydrostatically tested as the standard requires, and every order ships with an MTR stating heat number and country of melt.
✓ Type S (seamless) only
