How to distinguish between rigid dismantling joint and non-rigid dismantling joint from other aspects

Dismantling joint just one kind of Hesper’s expansion joints, it’s one of our main products. Rigid dismantling joint and non-rigid dismantling joint are two common connection devices.In last news we know how to distinguish them from the appearance, except from the appearance, they also have following differences:

First of all, in terms of function, non-rigid dismantling joint(also called double flange limited expansion joint) is mainly used to solve the expansion and displacement problems of pipeline systems, to protect pipeline systems from damage. While rigid dismantling joint(also called force transmission joint) is mainly used to transfer internal and external loads of pipeline systems to ensure the stability and safety of pipeline systems. This functional difference makes these two joints have obvious differences in design and application.

Secondly, from a structural point of view,non-rigid dismantling joint has special structures such as expansion body and limit device to adapt to the expansion and displacement of the pipeline system. The rigid dismantling joint has special structures such as force transmission element and sealing device to bear and transmit load and maintain sealing performance. This structural difference makes the two joints different in appearance.

Finally, from the application scenario, non-rigid dismantling joint(also called double flange limited expansion joint) is usually used in pipeline systems under complex working conditions such as large temperature changes, frequent vibrations or foundation settlement. The rigid dismantling joint(also called force transmission joint) is more suitable for pipeline systems that need to withstand large loads and harsh working conditions. This difference in application scenarios also provides a reference for us to choose the right joint in actual projects.

In summary, there are significant differences between rigid dismantling joint and non-rigid dismantling joint in terms of appearance, function, structure, and application scenarios. By carefully observing and analyzing these differences, we can quickly and accurately identify the two types of joints and make reasonable choices in actual projects. This not only helps improve the stability and safety of the pipeline system, but also reduces engineering costs and maintenance difficulty, providing a strong guarantee for the sustainable development of the enterprise.
