Flexible Bellow Metal Flange is an important industrial connection component, which is widely used in complex pipeline systems, especially in the case of limited spatial location conditions, and can solve various installation difficulties. Its structure includes a layer or multiple layers of steel wire or steel belt mesh sleeve outside the stainless steel corrugated pipe, and both ends are equipped with joints or flange heads for conveying flexible components of various media. The main function of the flange metal hose is to compensate the mutual displacement of the pipe or the connecting end of the machine and equipment, absorb vibration energy, and play the role of vibration reduction and noise reduction. In addition, it also has good water resistance, insulation, tensile, internal smooth structure, easy to wire and cable through, mainly used in production, processing cable protection and to achieve insulation, waterproof effect.
