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 air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications. ASTM A53 Pipe Types The following types and grades of A53 pipe are covered within this specification:
Type F – Furnace-butt-welded, continuous welded Grade A
Type E- Electric-resistance-welded, Grades A and B
Type S- Seamless, Grades A and B
ASTM Specification A53 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. U. S. Steel Tubular Products does not produce galvanized pipe.
