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.
The weld seam is heat treated after welding without untempered martensite remains. Also, the weld flash can be removed from both inner and outer surfaces.
适用于焊接,适合forming operations involving coiling, bending, and flanging, subject to certain qualifications.
