API 5L X80 Delivery Conditions & More
The delivery condition of API 5L X80 pipe changes the metallurgy, toughness and ultimately the grade suffix stamped on the pipe. PSL1 material is typically supplied as-rolled or normalized, while PSL2 X80 grade is almost always quenched & tempered (X80Q) or thermomechanically rolled (X80M) to meet the tighter toughness and sour-service requirements of transmission pipeline projects. The table below maps each delivery condition to its corresponding grade designation.
| PSL | Delivery Condition | Grade |
|---|---|---|
| PSL 1 | As-rolled, Normalized, N+ rolled, TM formed/rolled | X80 |
| PSL 2 | Quenched and Tempered | X80Q |
| Thermomechanical Rolled/Formed | X80M |
