API Spec 5L Steel Pipe Description

API-5L  welded spiral steel pipe is made of hot-rolled strip or steel plate as  raw material. The strip or steel plate is rolled into a round or  special-shaped steel pipe by a forming machine, and then the formed  steel pipe is butt welded by a high-frequency welding unit. PSL1 and PSL2 pipelines have different levels of quality requirements. This kind of steel pipe has the advantages of high strength, high toughness, corrosion resistance, and easy welding. API Spec 5L steel pipes are commonly used to manufacture pipeline steel pipes in the oil and gas industry.

Scope of Application

API Spec 5L specifies the manufacture of  two product levels (PSL1 and PSL2). PSL refers to the product  specification level established for the API 5L standard. Piping  specification classes are classified into PSL1 and PSL2. For pipeline  standards, PSL1 and PSL2 pipelines have different levels of quality  requirements. API Spec 5L pipeline steel plate is used to manufacture  pipeline steel pipes that extract oil, steam, and water on the ground in  the oil and gas industry.
