ANSI API 5L establishes the manufacture of two levels of products (PSL1 and PSL2) seamless and welded steel pipes for the use of pipes in the transportation of petroleum and natural gas. For use of materials in acid service applications, see Appendix H; for offshore service applications, see Appendix J of API 5L 45th Edition.
Process
Ingots, blooms, billets, coils or plates used for making pipes must be made through basic oxygen, electric furnaces or open fires combined with the refining process. For PSL2, it must be melted according to the practice of fine grains. The coil or plate used for the PSL2 pipe must not contain welds.
