API 5L is the standard specification for the samless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. It includes the requirements for the manufacture of two product specification level (PSL1 and PSL2), and there are differences for the two levels in each grade.

Manufacturing Types in Seamless, ERW, LSAW, SSAW, HSAW, DSAW
API 5L Pipe in Seamless Type inlcuding Hot Rolled Seamless and Cold Rold Seamless. Outer Diameter for this type normally under 24 inch.

Welded Type inlcuding:
ERW: Electric Resistance Welded, for manufacturing pipes OD under 24 inch.
SAW/DSAW: Submerged Arc Welded (Double Submerged Arc Weldedd), for manufcturing pipes OD up to 100 inch.
LSAW: Longitudinal SAW, OD up to 48 inch.
SSAW/HSAW: Spiral/Helical SAW, OD up to 100 inch.

Advantage

1. The thicker the wall thickness of the product, the more economical and practical it will be. The thinner the wall thickness, the higher the processing cost will be;
2. The process of this product determines its limited performance. Generally, the precision of seamless steel pipe is low: the wall thickness is uneven, the surface brightness inside and outside the pipe is low, the sizing cost is high, and there are pits and black spots on the inside and outside of the pipe, which are difficult to remove;
3. Its detection and shaping must be processed offline.
Therefore, it has its advantages in high pressure, high strength and mechanical structure materials.
