This specification covers seam welded ferritic-martensitic stainless steel pipe intended for abrasive and general corrosion service. The pipes are classified according to sizes, from NPS 2 to NPS 36. The pipe shall be made using Electric Resistance Welding (ERW) or an automatic fusion welding process with no addition of filler metal during the welding process. All pipes shall be made from heat treated strip or plate, cold formed and welded. Tensile test, flattening test, hydrostatic test, and nondestructive electric test shall be made in accordance with the pipe specification to conform to the requirements specified.
