API 5L X42 SSAW Steel Pipe For Oil and Gas Industry
Specifications
API 5L X42 SSAW (Spiral Submerged Arc Welded) steel pipe is a carbon steel line pipe engineered for petroleum and natural gas transportation. It features a minimum yield strength of 42,100 psi (290 MPa) and is manufactured by spirally welding steel coils. This process allows for large-diameter production, often used in low-to-medium pressure systems, with quality standards defined by Product Specification Levels PSL1 or PSL2.

→SSAW Pipe is transported in containers
(Nesting Packaging): Large-diameter SSAW pipes can be nested within one another, similar to Russian dolls, to utilize the internal space of larger pipes and minimize the volume of the cargo. This is a "game-changer" for reducing freight expenses and improving supply chain efficiency.
SSAW Pipe is transported by bulk carrier
