Description
Casing: 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 *5,**0 psi.�
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.
