Metal corrugated compensator is a flexible pressure-resistant pipe fitting installed in the pipeline transportation system, which is used to compensate the mutual displacement of the connecting ends of pipes, machinery and equipment, absorb vibration energy, and play the role of vibration reduction and noise reduction. It has the characteristics of good flexibility, light weight, corrosion resistance, high and low temperature resistance.

Metal hose is an elastic element composed of corrugated pipe, metal mesh, flange or connecting pipe. Because metal hose has no compensation, it is mostly used at the inlet and outlet of pump or equipment to reduce noise and vibration.

The main performance similarities and differences between the metal hose and the bellows compensator: only the bellows has better air tightness than the metal hose. Because the corrugated pipe is made of single piece material and the metal hose is a flexible element wrapped with stainless steel tape, it cannot prevent slight air leakage. However, with the continuous progress of metal hose technology, its air tightness will be higher and higher. It is suitable for conveying steam, water, oil and various industrial gases, drugs and other media.

For the movement of the pipeline system, the metal hose has good flexibility, temperature resistance, pressure resistance and corrosion resistance. Thermal expansion absorption and vibration absorption play an important role.

Due to the superior performance of the metal hose, the model length and connection mode are determined according to the user's requirements. Metal hoses are widely used in aviation, aerospace, oil pipelines and other devices. Make its application scope expand rapidly. The missile transfer vehicle is an important support equipment for the whole missile launch preparation stage. Its performance is directly related to the mobility of the missile transfer vehicle and provides a strong guarantee for the deployment of the entire missile launch site. Metal hose is an important part of the transfer vehicle. It is mainly used at the connection between engine and exhaust system. It mainly plays the role of noise reduction, vibration absorption and flexible connection.
