API 5L X52 ISO 3183 Gr L360/ L360N LSAW Welded Steel Pipe
The API 5L standard names tubes based on their minimum yield strength. Therefore, X52 (L360) has a minimum yield strength of 52,200 psi (360 MPa).
X52=L360, are two ways of expressing the same pipe grade in API 5L standard.
X52 is an intermediate grade in API 5L, combining high strength with economy. Widely used in oil and gas transportation, construction projects, submarine pipelines, etc.
ISO 3183 is the International Standardization Organization standard for the Petroleum and natural gas industries —Steel pipe for pipeline transportation systems. This International Standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
