API 5L PSL-1 X52/ API 5L PSL-2 X52 welded steel pipe is our main product. API 5L PSL-1 X52 welded/ seamless steel pipes and API 5L PSL-1 X52 welded/ seamless steel pipes have several differences as follow.
Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries. The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.
