Tubing & Casing

Casing: Casing is a wide range pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing,  to allow drilling fluid to circulate, and extraction to take place. 

Tubing: Tubing is 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.


Standards and Technical Conditions for Supply:API Spec 5CT ISO13680

Steel Grade: H40、J55、K55、M65、L80-1、N80-1、N80Q、C90、P110、Q125
Uses:Casing serves as well sidewall
Tubing is used for extracting petroleum and natural gas from  well;

Casing serves as wells of a well.
