How to Choose Between API 5L X60/L415 PSL1 and PSL2
API 5L X60 Q Line Pipe
API 5L X60 SSAW Pipe
API 5L X60 N Seamless PipeAPI 5L PSL2 has stricter limits on S, P, and C content than PSL1, it also requires additional NDT (non-destructive testing), CVN impact tests, full traceability is mandatory for PSL2. API 5L PSL2 X60 is preferred for more demanding and sour service conditions.
| Characteristic | PSL1 Standard | PSL2 High-End Specifications | Differences in Application |
|---|---|---|---|
| Chemical composition | C≤0.28%, S≤0.030% | C≤0.24%, S≤0.015% | Resistance to hydrogen sulfide corrosion increased by 300% |
| Mechanical properties | Yield strength ≥415MPa | Yield strength ≥415MPa | High-pressure transmission core indicators |
| Impact toughness | Optional | -30°C CVN≥40J | Mandatory requirements for Arctic/deep sea projects |
| Nondestructive Testing | Random inspection | 100% UT/AUT+RT | Welding defect detection rate 99.9% |
Microalloying technology analysis: PSL2 grade X60 adopts Nb/V/Ti microalloying design, with grain refinement to ASTM grade 12, which significantly improves low temperature toughness
X60 Position in the API 5L /L415 Strength Grade System
The API 5L standard divides grades according to the minimum yield strength (unit: ksi), forming a complete strength sequence:
- Medium-high strength level: between basic level (X42-X52) and ultra-high strength level (X70/X80).
- Performance balance point: taking into account high strength, good weldability and toughness, it is one of the mainstream choices for onshore/offshore trunk pipeline networks.
| Grade Level | X42 | X46 | X52 | X56 | X60 | X65 | X70 | X80 |
|---|---|---|---|---|---|---|---|---|
| Tensile Strength(min) | 42 ksi (290 MPa) | 46 ksi (315 MPa) | 52 ksi (360 MPa) | 56 ksi (390 MPa) | 60 ksi (415 MPa) | 65 ksi (450 MPa) | 70 ksi (485 MPa) | 80 ksi (555 MPa) |
Applications of API 5L X60 Pipes of Different Manufacture Technologies
