Bellows (a flexible element) constitute a body of work by the end of the tube, bracket, flange, catheters and other accessories. Is a form of compensation components. Its working body bellows expansion and contraction deformation to absorb the axial direction of the pipelines, conduits, containers, such as dimensional changes generated by thermal expansion and contraction and other reasons, or to compensate for pipelines, conduits, containers, etc., lateral and angular displacement. Also be used for noise damping. Widely used in modern industry. Heating, in order to prevent the temperature of the heating pipes, due to thermal elongation or temperature stress caused by deformation or destruction of the pipeline, the need to set the compensation pipe elongation, in order to compensate for the heat pipe, thereby reducing the wall stress and The force acting on the valve member or stent structure.
