How To Choose The Right Casing Pipe

Casing pipe is a type of OCTG pipe. Unlike drill pipes, which are all used in the drilling process, casing pipe is a pipe protection material, mainly used to protect wires, cables, water pipes, gas pipes and other equipment. According to different materials, casing pipe can be divided into different types such as PVC casing pipe, nylon casing pipe, metal casing pipe, etc. Different casing pipe materials are suitable for different environments and places.

Casing pipe selection specifications

1. Pipe size: When selecting casing pipe, the size of the pipeline should be considered first. The inner diameter of the casing pipe must be larger than the outer diameter of the pipeline. At the same time, the wall thickness and bending radius of the casing pipe should also be considered to ensure the protective effect of the casing pipe.

2. Environmental factors: When selecting casing pipe, the environmental factors such as temperature, humidity, and corrosiveness of the pipeline should also be considered. For high temperature environments, casing pipe materials that can withstand high temperatures should be selected; for humid environments, casing pipe materials that are resistant to moisture should be selected; for corrosive environments, corresponding anti-corrosion casing pipe materials should be selected.

3. Thermal expansion coefficient: When selecting casing pipe, the material and thermal expansion coefficient of the pipeline should also be considered. If the thermal expansion coefficient of the pipe material is different from that of the sleeve, it will cause stress in the sleeve when the temperature changes, affecting the protective effect of the sleeve. Therefore, when selecting the sleeve, the thermal expansion coefficient of the pipe material should also be considered.

4. Installation method: Different sleeves have different installation methods, such as fixed sleeves, telescopic sleeves, hoses, etc. Choose the appropriate sleeve installation method according to the specific application scenario.

5. Other factors: When selecting the sleeve, pay special attention to other factors such as the fire resistance, wear resistance, and waterproof performance of the sleeve.

Casing pipe selection method

1. Understand the specific parameters of the pipeline, such as pipeline material, pipeline size, pipeline length, etc.;

2. Understand the environment and use conditions of the pipeline;

3. Understand the material of the sleeve, such as PVC material, nylon material, etc.;

4. Select the appropriate sleeve material and model according to the specific situation;

5. Install and adjust according to the size, installation method and other requirements of the sleeve.

Summary

The sleeve is a very important pipeline protection material. The correct selection can improve the safety and life of the pipeline. When selecting the casing pipe, it is necessary to comprehensively consider the pipeline size, environmental factors, thermal expansion coefficient, installation method and other factors, select the appropriate casing pipe material and model, and then install and adjust it according to the requirements to ensure the long-term operation and protection of the pipeline.
