API 5L PSL1 / PSL2 Line Pipe X42, X52, X56, X60, X65, X70

API 5L PSL1/PSL2 Line Pipe

 

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.

API 5L Pipe Chemical And Mechanical Properties

The yield strength of an API 5L pipe is specified with the number that follows the X in the material grade designation (in kilo pounds per square inch – i.e. KSI). So, for instance, an API 5L X52 pipe has a minimum yield strength of 52 KSI.

The table shows the chemical composition of API 5L steel pipes PSL1 and PSL2 from Grade A to Grade X70, as well as their mechanical properties.
