Product Description

Threaded And Coupled Seamless Casing Pipe L80 Alloy Steel Oil Tubulars

Oil casing descriptions:

Oil casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells

or wellbore.

It is inserted into the well bore and cemented in the well, protect both subsurface formations and the

wellbore from collapsing, allow drilling fluid to circulate in it and extraction to take place.

Features:

1. 4 1/2”-20” seamless casing
2. Hot rolled pipe
