Seamless Casing Pipe

Product Introduction.

Pipe run from the surface and intended to line the walls of a drilled well. It is made of seamless pipes. 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.
