What problems may occur during the use of rubber expansion joints?

Bendable rubber expansion joint in the use of a variety of different abnormalities, whether the rubber expansion joint problems or environmental problems, we should be sensible to face, first solve the problem, and then the responsibility of the investigation. The following huanzhong/luoying to explain the rubber expansion joint in the use of the process will appear some minor problems.
First is the problem of cracking or cracks. Some small cracks may not be very obvious, in the rubber expansion joint after sun exposure, with the passage of time will appear aging phenomenon, and the degree of this damage also varies, but if this happens, it needs to be replaced in a timely manner. So in use, we should try to avoid rubber soft joints in the sun or wind and rain.
Second, blister deformation delamination, if there is a small part of the surface blister or deformation, we should not be anxious, because this case of rubber expansion joint will not affect the performance of the product, to carry out regular inspection tour on it. If there is a large blister on the surface of the sphere, deformation or separation between the rubber, sometimes the separation of the rubber curtain layer can be observed, this time, the need to replace the flexural rubber expansion joint as soon as possible.
Third, the installation of the model. First of all, it should be verified that the rubber expansion joint is installed correctly; between the flanges, there is no difference in size, and the installation surface and the size of the surface is correct. Check for excessive elongation, excessive compression, lateral or angular. If the incorrect installation causes excessive displacement of the rubber flexible joint, the pipe should be adjusted and then replaced with a new rubber flexible joint to fit the existing installation.
Also, pay attention to leaks. If the leakage is found, we need to first see if the bolts are not tightened, if not for this reason, it is possible that the rubber soft connection ball damage or ball grinding design problems, you should immediately replace the rubber soft connection to ensure the normal operation of the pipeline.
