Product Information
Expansion Joint is also called the compensator, or the slip joint.By work constitute the main body of the bellows, bracket structure, and end of flanges, pipe and other accessories.as kind of compensation components.Use its work subject bellows telescopic deformation effectively, to absorb the size of the change of piping, pipe,container, etc which is produced by the reason of heat bilges cold shrink,or compensation pipeline, catheters, containers, axial, lateral and angular displacement.Can also be used for noise reduction vibration reduction.Widely used in modern industry. In order to prevent the heating pipe from high temperature, due to thermal elongation or deformation or damage of the temperature stress caused by pipeline,need to set on the pipeline compensator,To compensate for the thermal elongation Reducing wall stress and the role of force on the valve or bracket structure. Bellows Expansion Joints are great for accommodating axial, lateral and angular movements for a wide array of piping applications. Stainless steel bellows, as a flexible pressure-resistant pipe fittings, are installed in the liquid transportation system to compensate for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and silencing. They have many characteristics, such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance.Data Details
