Buried corrugated compensator device precautions: in order to make the buried corrugated compensator play a compensating role, the compensator is necessary to set up a fixed bracket at both ends, to avoid the pipeline by the internal pressure thrust influence outward stretching.
Test pressure process to buried corrugated compensator shall not present stretching phenomenon. One end of the compensator should be close to one end of the fixed bracket, with the compensator's active head compensation pipeline.
According to the compensation amount of the buried corrugated compensator set the distance between the two fixed brackets, the compensation amount is generally not greater than the diameter of the pipe. Usually, the connection of buried corrugated compensator are welding. Corrugated compensator selection we should pay attention to the hard index, the design is reasonable. The general amount of pre-stretching is half of the compensation amount, the purpose is to increase the number of fatigue and service life.
