SSAW steel pipe classification

Spiral Submerged Arc Welding (SSAW) steel pipes are manufactured using strip coil as raw material. These pipes are formed by extruding the material at normal temperatures and welded with an automatic double-wire double-sided submerged arc welding process. Here, we explore the classifications and applications of SSAW steel pipes.

Classification of SSAW Steel Pipes

1. SSAW Steel Pipe (SY5036-83) for Pressurized Fluid Transportation:

   - Primary Use: These pipes are mainly utilized for conveying oil and natural gas through pipelines.

2. SSAW Steel Pipe (SY5038-83) for Pressurized Fluid Transportation:

   - Manufacturing Method: These pipes are welded using a high-frequency welding method.

   - Features: They have a strong load capacity, good plasticity, and are easy to weld and shape, making them suitable for various applications.

3. SSAW Steel Pipe (SY5037-83) for General Low-Pressure Fluid Transmission:

   - Manufacturing Method: These pipes are welded using a double-sided automatic submerged arc welding method or a one-sided welding method.

   - Primary Use: They are mainly used for transporting water, gas, air, steam, and other general low-pressure fluids.

General Standards for SSAW Steel Pipes

- 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 standard, also known as pipeline steel pipe, which is divided into PSL1 and PSL2 categories.

- SY/T5040-92: Standard for spiral seam submerged arc welded pipe for piles.
