ASTM / ASME Grade A Galvanized Metal Pipe Anti - Corrosion For Line Pipe
Materials and Manufacture
1 The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric-furnace, or basic-oxygen.
2 When steels of different grades are sequentially strand cast, identification of the resultant transition material is required. The producer shall remove the transition mate-rial by any established procedure that positively separates the grades.
3 The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding to a minimum of 1000°F [540°C] so that no untempered martensite remains, or otherwise processed in such a manner that no untempered martensite remains.
