Caing pipe L80 ,N80 casing tubing - Higher Overall performance Steel Grades
Caing pipe L80 , N80 casing tubing - Higher Overall performance Steel Grades
L80 HC is usually a controlled yield strength solution with demonstrated collapse resistance exceeding the minimum values for regular API L80.
L80 is actually a controlled yield strength solution using the highest demonstrated collapse resistance and with all the added benefit of a greater than minimum internal yield pressure than normal API L80.
| CASING TUBING | Minimum Yield | Maximum Yield | Minimum Tensile | Maximum Hardness |
|---|---|---|---|---|
| L80 Casing pipe H-C | 80,000 psi | 95,000 psi | 95,000 psi | 23.0 HRC |
| L80 Casing pipe H-P | 85,000 psi | 95,000 psi | 95,000 psi | 23.0 HRC |
| N80 Casing pipe H-C | 80,000 psi | 110,000 psi | 100,000 psi | None |
| N80 Casing pipe H-P | 95,000 psi | 110,000 psi | 100,000 psi | None |
N80 HC is a product having a demonstrated collapse resistance exceeding the minimum values for regular API N80.
N80 HP is really a product with all the highest demonstrated collapse resistance exceeding the minimum internal yield stress for typical API N80.\
