Line pipe

Casing: Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or the wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the well bore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth walls & a minimum yield strength of 35,000 psi.

Tubing: Tubing is a pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as 'upsetting' is applied to thicken the pipes.

API 5L pipeline is widely utilized in transporting petroleum, gas, water, and in the 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 an API 5L pipeline is transported from the underground to the oil and natural gas industry corporation for further processing and production. Oil and gas pipeline includes seamless pipe and welding pipe and has three plain ends, threaded ends, and socket ends. 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 kilopounds 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.
