API 5L X52 pipe is also known as L360 pipeline steel pipe. And they are named by the minimum yield strength 52 Ksi (360 Mpa) respectively. API 5L X52 is a medium strength grade in API 5L specification. API 5L X52 steel covers API 5L X52 PSL1 and API 5L X52 PSL2. With adequate API 5L X52 pipe properties, API 5L X52 pipe is widely used for oil and gas pipeline transmissions.
