Product introduction

Casing Pipe 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 35,000 psi.

API 5CT standard oil casing plays an important role in preventing oil well from being damaged by shallow oil layer and supporting the transportation of oil and gas. What’s more, casing pipe can support the weight of the wellhead layer to prevent collapse. API 5CT casing pipe ensure the smooth progress of the whole drilling process, after that, transport oil and gas from drilling to ground.
