API 5L: is the standard for pipeline steel pipes in the oil and gas industry, which specifies the technical requirements for the manufacture, performance, inspection and delivery of steel pipes to ensure the safety and reliability of steel pipes in the oil and gas transportation process.

PSL2: is one of the product specification levels in the API 5L standard, which represents a high quality requirement. Compared with PSL1, PSL2 has more strict regulations on the chemical composition, mechanical properties and non-destructive testing of steel pipes.

 

X70: is a steel grade mark, indicating that the pipeline steel pipe has excellent strength and toughness and other mechanical properties, can be applied to high pressure, large flow of oil and gas transmission.

 

MO: May represent a specific alloying element.

 

API 5L PSL2 X70MO Pipeline steel pipe Features:

 

High strength and toughness: The X70 steel grade ensures the high tensile strength and yield strength of the steel pipe, and has good toughness and can withstand large external forces.

 

Excellent corrosion resistance: Through specific chemical composition and treatment methods (such as MO), the steel pipe shows excellent corrosion resistance and effectively extends the service life.

 

Good weldability: The welded joint of the steel pipe is stable, easy to weld and connect, to ensure the integrity and reliability of the pipeline system.

 

The chemical composition of API 5L PSL2 X70MO pipeline steel pipe mainly includes conventional elements such as carbon, silicon, manganese, phosphorus, sulfur, and specific alloying elements added in order to optimize the performance of the steel pipe. These alloying elements may include chromium, molybdenum, nickel, etc., which can improve the corrosion resistance, strength and toughness of the steel pipe and other key properties.

 

The delivery status of API 5L PSL2 X70MO pipeline steel pipe is usually determined according to customer requirements and contractual agreements. Under normal circumstances, the steel pipe is delivered in hot rolled or normalized state, and such a treatment state can ensure that the steel pipe has good mechanical properties and weldability. At the same time, according to the special requirements of customers, the steel pipe can also be further heat treatment or surface treatment to meet the specific conditions of use and environmental requirements.
