Three common failures of non-metallic expansion joints: As the reaction of external conditions is also the main element that causes the fault of non-metallic expansion joints, so we need to enhance the performance of its anti-erosion and so on. Non-metallic expansion joints are widely used in hot air systems and fume ducts, after installation and operation, there are usually the following three failure situations: First, in the test pressure stage due to improper support or perhaps due to improper installation of the bracket and the effect of the goods, which requires us to consider the size of the pressure and the degree of load it can accept in the design process. Second, because the reaction of external conditions is also the main element that causes the non-metallic expansion joint fault, so we need to enhance the performance of its anti-erosion. Third, in order to protect, for the use of insurance, we should make every effort to improve its stability and strengthen its insurance protection. Therefore, for the non-metallic expansion joint failure situation, we need to give more consideration to the compensator in transport, before installation and installation of follow-up maintenance issues, so that we can do everything.
