PSL2 pipelines are produced in accordance with higher national standards and are mainly used to transport fluid media such as oil and natural gas. Their production and inspection standards are more stringent than PSL1, requiring companies to strictly control the quality of raw materials and welding processes during the production process. , anti-corrosion measures, etc. to ensure product quality and reliability.
In general, PSL2 pipelines have higher standards and requirements than PSL1 pipelines in terms of quality, pressure bearing capacity, anti-corrosion performance, reliability, etc. The specific choice of pipe depends on actual needs and engineering requirements.
The Difference Between PSL1 And PSL2 Pipes - Chemical Properties
| PARAMETER | PSL1 | PSL2 |
|---|
| Chemistry: Max C for Seamless pipe | 0.28% for grades ≥ B | 0.0024 |
| Chemistry: Max C for Welded pipe | 0.26% for grades ≥ B | 0.0022 |
| Chemistry: Max P | 0.03% for grades ≥ A | 0.0003 |
| Chemistry: Max S | 0.0003 | 0.0002 |
| Carbon equivalent: | Only when purchaser specifies SR18 | Maximum required for each grade |
