Products Description
American Petroleum Institute specification big diameter API 5L X52 steel pipe includes seamless and welded pipe. It is steel pipe used in pipeline transportation systems for the oil and gas industry.API 5L line pipe is suitable for the transportation of gas, water and oil.
The big diameter API 5L X52 steel pipe specification follows the International Organization for Standardization ISO 3183, which standardizes materials, equipment and pipeline transportation systems within offshore structures for the oil, petrochemical and gas industries. The technical committees that develop these standards recognize that there are two basic product specification levels (PSL) of technical requirements and have developed PSL 1 and PSL 2. PSL 1 is the standard quality for line pipe, where PSL 2 contains additional chemical, mechanical properties and performance Testing Requirements.
