This specification covers electric-resistance-
welded low-carbon steel pipe for use as process lines in chemical industries. The steel shall be aluminum killed steel made by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace. The steel may be cast in ingots or strand cast and the pipe shall be made by electric resistance welding. Pipe furnished in the as-welded condition shall be normalized at a temperature above the upper critical temperature. Cold-drawn pipe shall be normalized after the final cold-draw pass. The pipes shall undergo the following tests: tensile test, flattening test, reverse flattening test, flange test and nondestructive tests. The nondestructive tests shall include eddy-current test, ultrasonic test, and flux leakage test.
