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.
