covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures. Heat treatment may or may not be required to attain the desired mechanical properties. The pipes are classified according to steel grades and are designated in classes according to the type of heat treatment performed in the pipe manufacture, whether the weld is radiographically examined, and whether the pipe has been pressure tested. The steel welds shall be made either manually or automatically by an electric process involving the deposition of filler metal. The welded joints shall have positive reinforcement at the center of each side of the weld. The contour of this reinforcement shall be smooth, and the deposited metal shall be fused smoothly and uniformly into the plate surface. The joints shall undergo tension, bend and pressure tests. Unacceptable surface imperfections shall be removed by grinding or machining. The depression after grinding or machining shall be blended uniformly into the surrounding surface. Repair of weld and base metal defects shall be done by welding.

*A Requires quenching and tempering.
*B 9CR steel is an air-hardenable steel, at times retaining austenite down to near atmospheric temperature. Good practice is to allow the steel to cool to 150° For lower before subjecting the steel to a tempering treatment or post-weld heat treatment.

As with all ASME and ASTM pressure vessel steels, Chrome Moly to SA387 and A387 is produced in conformity to SA20 / A20 which outlines the testing and retesting methods and procedures, permissable variations in dimensions and weight, quality and repair of defects, marking, loading, and ordering information.

In addition to the basic requirements of SA20 / A20 certain supplementary requirements are available when additional control, testing, or examination is required to meet end use requirements. These might include product analysis (S2), charpy V-notch impact test (S5), or ultrasonic testing (S12): a variety of supplementary requirements are available.
