API 5L PSL1 Carbon Steel Seamless Pipe - Knowledge

PSL1 pipeline steel‌ is a commonly used pipeline material in the oil and gas industry, with its full name being ‌"Pipeline Steel Level 1"‌. It is one of the pipeline steel grades defined in the ‌API 5L‌ standard. This standard, established by the ‌American Petroleum Institute (API)‌, aims to regulate the manufacturing, inspection, and performance requirements of pipeline steel, ensuring safe operation of pipeline systems under complex conditions such as high pressure and low temperatures.

As a basic grade, PSL1 is primarily suitable for general transportation scenarios, including onshore oilfield gathering pipelines and urban gas pipelines.
