Characteristics of Bellows Coupling Yichang Pipeline

Henan Yichang pipeline equipment specializing in the production of corrugated compensators, waterproof casing, rubber joints, expansion joints and other products.

The tube coupling consists of two hubs and a thin-walled metal tube that are joined together by welding or bonding. Although many other materials are available, stainless steel and nickel are the most commonly used metal tube materials. Nickel tubes are completed by electrodeposition. This method first machines the solid mandrel into a corrugated shape, uses electroplated nickel on the mandrel, and then the mandrel is chemically dissolved to obtain a nickel bellows. This method can control the accuracy of the wall thickness of the bellows, and can obtain a thinner wall thickness than the bellows made by other methods. This thin-walled bellows makes the coupling highly sensitive and responsive, making it ideal for use in extremely small and delicate instrument applications. So the bellows coupling has the following characteristics:

High torque rigidity and excellent sensitivity, maintenance-free, superior oil resistance and corrosion resistance , zero rotation clearance , exactly the same clockwise and counterclockwise rotation characteristics , stainless steel bellows structure compensates angular axial deviation , commonly used with servo motor, step Into the motor and other joints , the main material: aluminum alloy, installation methods: top screw fixed type, clamping fixed type, expansion sleeve fixed type.
