Specific requirements for the use of corrugated expansion joints

Corrugated expansion joint is a device with expansion function composed of metal bellows and components, which can compensate the thermal deformation of the pipeline, mechanical deformation and absorb various mechanical vibrations, playing a role in reducing the deformation of the pipeline and improving the service life of the pipeline. The reason why corrugated expansion joints are widely used in many industries, in addition to the consideration of good compensation capacity, reliability is the key to bellows compensator expansion joints. Reliability is ensured by multiple links such as design and manufacturing, and negligence in any one link can lead to a reduction in the life of the compensator or even failure.
 
Specific requirements for the use of corrugated expansion joints: follow the "1:1" rule to set the expansion joint. A straight heat pipe set bellows expansion joint, should follow the "1:1" ratio rule, a fixed bracket set an expansion joint, not set two or more number of expansion joints, so as not to lead to uneven load, seriously endanger the heat pipe heating efficiency and the use of specifications. The stiffness and strength of the bracket need to meet the relevant standards. When selecting fixed brackets, the quality should be strictly controlled and the testing should be put on the stiffness and strength of the brackets to ensure that the quality of the brackets used for heat pipes is up to standard as far as possible. In addition to the fixed bracket, should also pay attention to the data of the guide bracket and spring hanger and other components to observe whether it can match the displacement form of the expansion joint, if not should make timely adjustments.
 
Corrugated expansion joints of the same pipe diameter: when matching materials, it is necessary to add the same pipe diameter of the sub-fixed brackets together and ensure that they are on the same horizontal straight line as far as possible to reduce the actual bearing value of the sub-fixed bracket blind force to achieve the purpose of enhancing the coefficient of the heat pipe and extending its service life. It can be seen that corrugated expansion joints are suitable for heat pipes with lower temperature, smaller pressure and shorter length, and have strong economy, practicality and space saving, which can effectively realize the optimal and reasonable allocation of resources and ensure the normal heat supply of heat pipes. Due to the strong plasticity of the expansion joint and the softness of the tube body, this requires the technicians to strictly follow the relevant regulations in the specific installation process, to enhance the efficiency of the heat pipeline as much as possible on the basis of stability, and effectively reduce the amount of heat loss in the transportation process.
