The expansion joints adopts rectangular section and fillet shape, and the single expansion joint in the pipeline is subjected to two dimensional displacement.
1, after the user has selected the appropriate compensator according to the thermal displacement of the piping system, at least have to provide the flow medium in the pipe, the design pressure of smoke duct, the highest temperature during operation, and the size of duct waveform wave cross section selection, structure design and manufacture for compensator.
2, in order to reduce the wave number of bellows, cold drawing should be considered 50%.
3, The compensator is suitable for occasions where the sectional area is less than 4.6 square meters and the shape of the flue duct has a side smaller than 1.5m but greater than 0.6mm.
