Standard Specification for Electric-Resistance-Welded Low-Carbon Steel Pipe for the Chemical Industry

Fecha:

Abstract:

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.

Scope:

1.1 This specification2 covers electric-resistance-welded low-carbon steel pipe intended for use as process lines.

1.2 Pipe ordered under this specification shall be suitable for severe forming operations involving flanging in all sizes and bending to close radii up to and including NPS 4.

1.3 This specification covers NPS 1/2 through 10, plus additional sizes. The corresponding outside diameters and wall thicknesses for NPS 1/2 through 10 are listed in Table 1, as are the dimensions for the additional sizes.

Note 1The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”
