There are two types of vacuum corrugated hoses. One is a molded corrugated tube, which belongs to a flexible but incompressible vacuum hose, and the other is a flexible and flexible vacuum hose that is bendable and compressible. So how do we generally classify vacuum bellows according to the number of layers?
The classification method of vacuum bellows by layer is as follows:
- The single-layer bellows uses a single-layer bellows for vacuum fittings for multi-wall vacuum fittings that are compensated for displacements under static load. Its production is simple and the cost is low. Under the premise of ensuring the required pressure capacity, compensation amount, stiffness and fatigue life of the design, a single-layer corrugated pipe should be preferred.
- Multi-layer bellows is used for alternating loads or more important pipelines, and more than two layers of multi-layer bellows are used. Compared with single layer, under the same load capacity, the stiffness is smaller and the fatigue resistance is better.
The classification method of vacuum bellows according to the number of layers is mainly the above points, and selecting the appropriate vacuum bellows is the most important.
