ASTM A53 Welded Pipe

ASTM A53 is suitable for mechanical and pressure applications, as well as for general use in steam, water, gas, and air piping. It is suitable for welding and forming operations involving coiling, bending, and flanging, subject to certain qualification requirements.
A53 covers seamless and welded, ferrous and hot-dip galvanized nominal (average) wall pipe for coiling, bending, flanging and other special applications, and is suitable for welding. Continuously welded pipe is not suitable for flanging. The use of the pipe should be specified on the order.
