SSAW steel pipe  is the steel pipe with spiral seam that using strip coil as raw material, extrusion forming under normal temperature, and welding by automatic Double wire double-sided submerged arc welding process. Classification of SSAW steel pipe includes: 
1. SSAW steel pipe (SY5036-83) used for pressurized fluid transportation is mainly used for conveying oil and natural gas pipeline. 
2. SSAW steel pipe (SY5038-83) used for pressurized fluid transportation, it is welded with high-frequency welding method. The loading capacity of it is powerful, the plastic is good, and it is easy to weld and machine shaping. 
3. SSAW steel pipe (SY5037-83) used for general low-pressure fluid transmission, it is welded with double-sided automatic submerged arc welding method or one-side welding method, it is mainly used for water, gas, air and steam and other general low-pressure fluid delivery. 
Now general standards for SSAW steel pipe is generally divided into: SY/T5037-2000 (ministerial standard, also known as spiral submerged arc welded steel pipe for ordinary fluid transportation pipeline), GB/T9711.1-1997 (Chinese standard, also known as pipe for oil and gas industry transportation, API-5L (American Petroleum Institute, also known as pipeline steel pipe; which is divided into PSL1 and PSL2), SY/T5040-92 (spiral seam submerged arc welded pipe for pile).
