The existing metal expansion joints will have more classifications in the actual use process, and many people may not have a special understanding of their classification.

1. Elbow Expansion Joint

In the process of actual selection of these metal expansion joints, there will be expansion joints with different elbow styles. They are very different from other bodies. In the process of actual use of the expansion joints, the overall expansion strength will be achieved by using the elastic deformation properties of the body. The expansion joints can be widely used in various steam pipes because they occupy relatively large space, consume a lot of steel and have very large friction force. On roads and long pipes.

2. Corrugated expansion joint

In the actual expansion of existing expansion joints, basically they can effectively expand along the axis direction of different pipelines. In a small number of cases of allowable bending, because they are also some expansion joints, so the length of the pipeline can be not long in the axial direction, in order to prevent it. Over the original compensation amount, basically after the actual pull rod or protection, more guide brackets will be installed, in which there must be more angular or transverse expansion joints, which can be used to compensate for the angular and transverse deformation of pipelines, and even the advantages of such expansion joints can be effective. Save space, but also can continue to standardize and mass production, the disadvantage is relatively short life.
