PRODUCT DETAILS

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.
