ASME SA53 grade A pipe SA53 Gr A seamless steel tube

ASME SA53 grade A pipe SA53 Gr A seamless steel tube

Standard: ASME SA53

ASME SA53 grade A steel is equivalent to ASTM A53 grade A steel. SA53 grade A is also shorten as SA53 Gr A and SA53A. ASME SA53 grade A pipe covers 3 types: Type E - Electric-resistance welded pipe / ERW pipe; Type F - Furnace-butt welded, continuous welded pipe; Type S - Seamless pipe. When the ASME SA53 type S pipe is required for close coiling or cold bending, ASME SA53 grade A pipe SA53 Gr A seamless steel tube is preferred rather than SA53 grade B seamless pipe.
