Application characteristics of metal bellows expansion joints

The metal bellows expansion joint is composed of the corrugated pipe and end pipe, bracket, flange, conduit and other accessories that constitute its work. It is a compensation device used to absorb the dimensional changes of pipelines, ducts or containers due to thermal expansion and contraction by using the expansion and contraction of the elastic element of corrugated compensator, and belongs to a compensation element.
 
Application characteristics of corrugated metal expansion joints
 
Corrugated expansion joints can be axial, lateral, and angular displacement absorption, used in pipelines, equipment and systems of heating displacement, mechanical displacement absorption vibration, noise reduction, pumps, valves, air compressor import and export; machinery and equipment piping, the need for vibration damping and compensation of thermal displacement occasions, etc., the use of more.
 
Corrugated expansion joints are arranged next to the fixed bracket, and then connected to two guide brackets, the distance is 4Dg, 14Dg respectively.
 
Corrugated expansion joint in the underground obstacles, there may be more turning bend generation, requiring moment type corrugated expansion joint needs to be arranged in straight pipe section, this form of compensator on the side of the fixed bracket, may be caused by the pipeline displacement of corrugated expansion joint each wave section to absorb displacement of the work capacity of uneven transmission, so need to pay attention to.
