ASTM 36 is an American standard Carbon Steel Pipe, which implements the standard ASTM A36/A36M-03a, SSAW spiral submerged arc welded pipe, submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) The advantages of stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beams and columns. Submerged arc Welded Steel Pipe: It is a spiral seam Steel Pipe made of strip Steel Coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. The characteristics of submerged arc welded steel pipe: the production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is relatively fast. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe. However, compared with the same length of straight seam pipe, the length of the weld is increased by 30~100%, and the production speed is lower. Therefore, most of the welded pipes with smaller diameters use straight seam welding, and most of the welded pipes with large diameters use spiral welding.
