Pneumatic slips for oil drilling

Pneumatic slips are mainly used for oil drilling lifting and lowering operations, with the function of automatically clamping and releasing the drill string. ‌

Pneumatic slip is a mechanical device that uses compressed air as power to achieve automatic lifting and lowering of the slip body through the up and down movement of the cylinder, used to clamp drilling tools in the well during drilling operations. It has the functions of automatic centering and automatic disc scraping, which enables the drilling tool to be firmly clamped at any position, and the entire process only requires foot operation to complete the lifting and lowering of the drilling tool. This type of slip not only increases the speed of lifting and drilling operations, but also reduces the labor intensity of workers, improving the safety and efficiency of operations.

Common specifications, models, and characteristics of pneumatic clamps:

1. PS16 pneumatic slip: with a pipe diameter range of 3.1/2 to 22.3/8, a maximum load of 350 tons, and a working pressure between 0.6 and 0.8 Mpa.

2. Pneumatic casing hoist/slip: a tool suitable for lifting and lowering casing sizes of 114-340mm (41/2-14 in), using pneumatic operation, with the characteristics of labor-saving and safety.

3. Multi functional drilling string pneumatic slip: Suitable for various types of drilling rig turntables, it has the characteristics of easy installation, simple operation, pneumatic lifting, automatic mud scraping during drilling, safety and reliability. Suitable for a wide range of pipe diameters, with clear regulations on maximum load and working pressure.

4. Other specifications and models: This also includes various models with pipe diameters ranging from 2.3/8 to 20, with maximum working loads of 200 tons, 250 tons, and 700 tons, respectively.
