What is API 5L Line Pipe?

It is well-known that API 5L refers to API 5L line pipe, which is a international standard specifies requirements for manufacturing two products specification levels of seamless steel pipes and welded steel pipes for applications in oil pipeline transportation systems in the petroleum and natural gas industries. Two levels include PSL1 and PSL2. Additionally, the number of API 5L welded steel pipes is more than API 5L seamless steel pipes, due to lower cost.
