The second is that if it is inferior rubber joints, then it will have a certain lack of hardness, because the rubber joints not only have a certain degree of flexibility, its hardness is to have, so if you can not reach the hardness of the rubber joints rubber joints The quality is not very good; the third is the emergence of a one-way inferior rubber joint appearance of bubbles will self-guided telescopic compensator, maybe even delamination phenomenon. Because when the compensator is exposed when external pressure is too large, it is likely to cause the loss of all aspects of its performance, no way to carry out their normal work followed compensator media also contributed to the failure of the key, while some contain corrosive The media through compensation when it will cause the failure of the phenomenon; then is temperature compensated working surroundings, temperature compensation is too low, then there is no way to use a normal axial double bellows, and if the temperature is too High words are likely to cause direct damage compensation, but also affect the normal operation of the pipeline; this we can infer that the compensator failure exists with the surrounding environment has a certain contact has led to its failure occur phenomenon.
