Welcome to inquire! Contact: Zhang. Pressure test is divided into two types: gas pressure and liquid pressure. Gas pressure coefficient is usually 1.2 times the high-pressure reactive power compensation, while the liquid pressure is usually around 1.5 times. For example look at the inner bellows, for example, a bellows the working pressure of 10 kg. So do the test pressure in the liquid pressure when it should be about 15 kg, while doing the test gas pressure is required 12 kg on it. Because when the compensator is exposed when external pressure is too large rubber flexible compensation, it is easy to cause the loss of all aspects of its performance, and no way to carry out their normal work followed compensator media also contributed to the failure of a key location, While some media containing corrosive by compensating for the time it will result in the failure of the phenomenon; that is temperature compensated and then working surroundings, temperature compensation is too low, then there is no way normal use, and if the temperature is too high are likely to cause direct damage compensation, but also affect the normal operation of the pipeline; this we can infer that the failure of the compensator and the surrounding environment has existed a definite link has led to the phenomenon of its failure occur.
