Key features

Integral Spring Design: Made from a single steel plate with laser cutting and wire saw welding for higher strength and no stress weak points.

High Centralization Ratio: Features an 85% deviation clearance ratio and better reset force to ensure effective mud removal and cementing.

Low Friction & Wear Resistance: No initial resistance and less friction, reducing wear from contact with the borehole wall in horizontal wells.

Wide Size Customization: Available in sizes from 4-1/2' to 20', with custom sizes available on request to match well bore dimensions.

Versatile Well Applications: Suitable for vertical, deviated, horizontal, and geothermal wells, including high-temperature applications.

Turbulent Cementing Efficiency: Spinning disk forms a whirl channel to improve cement slurry displacement efficiency in turbulent spring models.

Robust Material Options: Constructed from high-grade steel, aluminum alloy, or optional polymer materials for corrosion resistance.

Strict Quality Control: 100% self-test before packaging and visual inspection of finished products to ensure reliability.
