Casing pipe is used for protecting subsurface formations. It also protects the bore hole form collapsing.
As an important part of the bore hole, casing has several important functions:
Prevent bore hole collapse, the isolation of different formations to prevent liquid convection between the formations and thus play a role in controlling the drilling fluid and pressure while drilling.
Assist ground control equipment and downhole production equipment to achieve their respective functions.
For different hole diameters and material can be with different grades.
Normally we provide J55,N80,L80,P110,G105,S135 grade raw materials for casing. Thread types commonly produced are LC,SC and BC. We can also customized as per drawings provided by our customer.
