The American Petroleum Institute created specification API 5L for use in the oil and gas as well as the petrochemical industries. These industries require strong and hard pipes which are able to withstand the various stresses in the application. Hence, they use API 5L Grade X60 PSL 2 for their applications. Essentially, these pipes are a carbon alloyed based component.
Carbon alloyed products like the ISO 3183 L415 pipe exhibit their usefulness in the highly stressful applications. Usually, the applications of the Api 5l X60 Smls entails the transportation of fluids or gases of different viscosity. In addition to varying viscosity, an additional stressor is the rate of flow of the media across the Api 5l Grade X60 Psl 2 pipes. High speed transportation can in several cases abrade the surface of the pipes. And their prolonged abrasion could, in turn, lead to failure or cracking. Therefore, in such instances, most suppliers recommend using Api 5l X60 Seamless Pipes, because, not only are they sturdy, but an absence of a seam on their body makes them very durable. Though the cost of a seamless variety is more than the Api 5l X60 Welded Pipe, their ability to withstand loads is higher as well. This being said, it is also possible to use welded Carbon Steel Api 5l X60 pipes for the transportation of media across sites to refineries. However, since these pipes ferry across combustible substances, one must ensure the weld joint on the Api 5l X60 Psl2 has high integrity.
