API 5L PSL2 X80 Seamless Steel Pipe
Basic Overview
A high-strength seamless steel pipe designed for high-pressure oil and gas transportation. It's stronger than X70 grade pipes.
Name Explanation
| Part | Meaning |
|---|---|
| API 5L | American Petroleum Institute pipeline standard |
| PSL2 | Product Specification Level 2 (higher quality than PSL1) |
| X80 | Minimum yield strength: 80,000 psi |
| Seamless | Made from solid steel (no weld seam) |
Key Specifications
| Property | Requirement |
|---|---|
| Grade | X80 |
| Min. Yield Strength | 80,000 psi (552 MPa) |
| Min. Tensile Strength | 90,000 psi (621 MPa) |
| PSL Level | PSL2 |
| Manufacturing | Seamless |
| Key Tests | Hydrostatic, NDT, Impact Test |
Main Advantages
Higher strength than X70 (can handle more pressure)
Lighter walls possible (saves material and weight)
Better for deepwater/offshore applications
No weld seam (more reliable)
Common Applications
High-pressure transmission pipelines
Offshore and subsea pipelines
Arctic/cold region pipelines
Sour service environments (with special requirements)
Note: X80 is about 14% stronger than X70, allowing for thinner pipe walls at the same pressure rating, which reduces material and transportation costs.
