Product Description

API Spec 5L is an international standard that specifies the manufacturing requirements for two product specification grades (PSL 1 and PSL 2) of seamless and welded steel pipes used in pipeline transportation systems in the oil and gas industry. 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 p ipes are commonly used to manufacture pipeline steel pipes in the oil and gas industry.
