What is the API 5L standard?

API 5L standard generally refers to the implementation standard of line steel pipes, which are used to transport the oil, gas, water, etc. extracted from the ground to the petroleum and natural gas industrial enterprises.

Material: GR.B, X42, X46, 52, X56, X60, X65, X70, X80

Outer diameter: 13.7mm-1219.8mm

Wall thickness: 2.11mm-100mm

The higher the requirements for API 5L steel raw materials and production, and the strict control of the carbon equivalent between different steel grades.

With the development of API 5L pipeline steel seamless pipe technology and the advancement of forming and technology, the application scope of API 5L pipeline seamless pipe is gradually expanding, especially the advantages of API 5L large diameter pipeline steel seamless pipe are more obvious. Coupled with cost factors, API 5L pipeline steel seamless pipe has occupied a leading position in the field of pipeline steel pipe, and the development of API 5L seamless pipe.
