ABOUT API 5L LINE PIPE

API 5L is a pipeline pipe standard specification developed by the American Petroleum Institute (API) , primarily used in the global petroleum industry, particularly for pipelines transporting crude oil, natural gas, and water. This standard covers manufacturing, inspection, testing, and quality control requirements for seamless and welded steel pipes, ensuring pipeline safety and reliability under high-pressure and harsh environmental conditions.

API 5L standard classifies products into distinct grades (such as X42, X52, X60, PSL1, and PSL2), each corresponding to specific strength levels and chemical compositions to meet diverse operational requirements. The standard also specifies technical requirements for pipe dimensions, wall thickness, surface treatment, and mechanical properties, ensuring corrosion resistance and wear resistance during transportation and service.

Yantai Xinbaoshang's products consistently adhere to the API 5L line pipe standard certification!
