Oil Tube&Casing pipe
Casing is a large-diameter 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 and to allow
drilling fluid to circulate and extraction to take place. Steel
Casing Pipes have smooth wall & minimum yield strength of
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.
