Axial type corrugated compensator selection

Axial type corrugated compensator selection
Among the specifications of the axial type corrugated compensator, the corrugated pipe is limited by column instability due to the common axial type in the application process. In order to apply the larger compensation volume and need to avoid column instability in the heating pipeline, the axial external pressure corrugated compensator solves this problem. Axial external pressure corrugated compensator 2.5TWY800*7-890J is used in the heating pipeline, the structure of the external metal sleeve protection, in order to avoid the bellows plane instability, the internal by four groups of bellows, the use of intermediate receiver for connection. The compensation capacity is increased.
The structure of the axial external pressure bellows compensator is mainly composed of a sleeve and a ring plate, which is subjected to elastic force and pressure. Although not able to withstand the pressure thrust of the bellows but can absorb the combination of axial and lateral displacement. Need to be used in buried pipes, in the selection of materials, need to take into account the medium, temperature and external environment, as well as the possibility of stress corrosion. According to the use of environmental installation for direct burial, in the installation of the pipeline directly buried in the soil, in understanding the hydrogeology of the situation, the need to pay attention to the corrugated compensator and the pipeline interface seal to avoid improper handling caused by leakage. Selection in addition to the above parameters also need to be the soil environment and water quality conditions as a reference factor. Selection of axial external pressure corrugated compensator needs to be combined with the use of the environment and the implementation of pressure, temperature, the amount of compensation required and the chemical properties of the medium.
