API 5L: A specification developed by the American Petroleum Institute for piping steel to ensure the safety and effectiveness of oil and gas pipelines.

PSL2: Product specification level for pipeline steel pipe, which defines the requirements for the manufacture, inspection and performance of steel pipe. Compared with PSL1, PSL2 has higher quality requirements.

 

X52: Indicates the strength grade of the pipeline steel, specifically, its minimum yield strength is 52,000 psi (approximately 358 MPa).

 

MO: May represent the special performance or improved version of the steel pipe, the specific meaning needs to refer to the relevant standards or manufacturer's instructions.

 

API 5L PSL2 X52MO pipeline steel is widely used in oil, natural gas and other energy transmission pipeline system. Due to its high strength and good toughness, it is especially suitable for long-distance transportation pipelines, submarine pipelines, and pipeline laying in complex terrain and harsh environments. These tubes ensure the safe and efficient transmission of energy to the destination and meet the various transmission needs.

 

The chemical composition of API 5L PSL2 X52MO includes conventional elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), which play a key role in the mechanical properties and corrosion resistance of steel pipes. In addition, it is possible to add some trace elements, such as nickel (Ni), molybdenum (Mo), copper (Cu), etc., to improve the strength and corrosion resistance of the steel pipe. The specific chemical composition ratio is determined according to the API 5L specification and the specific requirements of X52MO to ensure the performance and quality of the steel pipe.
