Expansion joints have different models and different structural forms. Their fields of use are also different, and the fields of use are also different. Generally speaking the sleeve type expansion joint is made by sleeve on the main body of the expansion joint. Therefore it must have good sealing and high temperature resistance. If the installation is not in place or the ambient temperature changes are relatively large and other reasons will lead to deformation and damage of the expansion joint, then it will need to be replaced.
The sleeve type expansion joint mainly uses the lateral movement produced when the metal pipe expands to achieve the expansion amount function. It is easy to install but there are requirements for the precision and displacement of the equipment during installation. For example, the expansion volume is too large to cause vibration of the pipe, which leads to damage of the joint and other problems. Because the expansion pipe does not have pre-buried bolts so can not play a compensation role and is used in some occasions for convenience can also play a certain role is very important. The telescope is mainly used to compensate for the distortion and deformation in the pipeline and make the connection produce expansion or displacement to achieve the purpose of compensation. At the same time can also play a role in protecting the pipeline from damage.
