API 5L Welded Spiral Steel Pipe is manufactured using hot-rolled steel strip or steel plate as raw material. During production, the strip or plate is formed into a round or specially shaped pipe through a forming machine, and the pipe edges are then joined by high-frequency butt welding technology to create a strong and reliable welded structure.

API 5L pipelines are generally classified into PSL1 and PSL2 grades, which represent different quality and technical requirement levels. PSL2 products typically have stricter standards for chemical composition, mechanical properties, and testing requirements compared with PSL1.

This type of steel pipe offers advantages such as high strength, excellent toughness, good corrosion resistance, and convenient weldability. Because of these properties, API 5L welded spiral steel pipes are widely used in the oil and gas industry for transporting petroleum, natural gas, water, and other fluids through long-distance pipeline systems.

Product Parameters

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.
