Casing Tube

The casing tube is resistant to chemical erosion, and it can withstand various external forces, like collision, bursting, tensile strength, etc. Casing pipes have two different functions: firstly, it can help to prevent the well walls from collapsing, as well as to control the formation fluids.

Advantages

1. This kind of casing tube is able to stabilize the borehole during the drilling process.
2. Casing pipes have two different functions: firstly, it can help to prevent the well walls from collapsing, as well as to control the formation fluids.

Features of Casing Pipes

The casing tube is resistant to chemical erosion, and it can withstand various external forces, like collision, bursting, tensile strength, etc.
Besides, it suits a wide variety of well diameters as well as different material grades. The specification is varying according to different drilling technologies.
1. During the operation process, workers need to check whether there are any damages at the tread connection point of the pipe. If there are any damages, please replace it immediately so as to avoid tripping when using this tube.
2. When connecting the casing pipes, thread sealing grease is quite necessary.
