Oil casing description:

Casing pipe is the major structural component of a well. The API 5CT Casing pipe is a large-diameter

steel pipe that serves as the structural retainer for the walls of oil and gas wells, and typically held into

place with cement.

API 5CT casing 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.

The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors,

and setting depth is a primary engineering and economic consideration.

Features:

1. Oil special pipe
2. International standard API 5CT
