What is the API 5L Pipeline?

API 5L pipeline is widely utilized in transporting petroleum, gas, water as well as in natural gas industry. API 5L refers to the American Petroleum Institute Prepared and Published all over the world.
Petroleum, crude oil, gas, water or natural gas through API 5L pipeline is transported from the underground to the oil and natural gas industry corporation for further processing production. Oil and gas pipeline includes seamless pipe and welding pipe and has three plain end, threaded end and socket end. Steel grade is mainly Grade B, X42, X46, X52, X56, X65, X70, and X80.

Seamless Pipe:

★Steel Grade: B, X42, X52, X60, X65, X70
