API 5L PSL2 X52QS line pipe is one of the most popular and running grades in all API 5L Grades from API 5L B to X100. This is cost-effective and durable for all oil and gas pipelines. It is also used in power generation plants, oil refineries, sour service, and off-shore piping projects. API 5L PSL2 X52QS line pipe is required quenched and tempered.
The tensile strength of API 5L X52 steel pipe is higher than API 5L X42, it is minimum value 66700 Psi (460 Mpa) . Grade X52 yield strength is 52,200 psi(360Mpa) that's why it is known as L360.
