Introduction of metal bellow
Flexible bellow also known as expansion joints.It is composed of a corrugated pipe (an elastic element), an end pipe, a bracket, a flange ,a conduit and other accessories.
Function of metal bellow
It mainly used in various pipelines, it can compensate the thermal displacement of the pipeline, mechanical deformation and absorption of various mechanical vibrations; Play a role in reducing deformation stress and improving the service life of the pipeline.
