1.Uniform wall thickness
2.High roundness accuracy
3.Three-layer welding to ensure excellent weld performance
4.Good insulation performance
5.Strong waterproof ability
6.High impact resistance under low temperature conditions to be directly buried in frozen ground
7.30-50 years service life
Overview of the development of welded steel pipe for natural gas transportation, there are roughly three types of pipes, SAW pipes, including straight seam submerged arc welded pipes (LSAW) and spiral submerged arc welded pipes (SSAW), Seam Welded Pipe (ERW) and Seamless Steel Pipe (SMLS). The most natural gas tubing is underground steel gas pipe.
Usually, we mainly focus on three technical requirements of steel gas pipe, strength, stiffness and impact toughness.
1. Composition and Mechanical properties of commonly used carbon steel alloy steel.
2. Seemless steel pipe, welded pipe, etc.
3. A series international universal series, domestic series.
