AI Technical Summary
Existing copper pipe joints are prone to fatigue and breakage under vibration, which can affect the normal operation of instrument piping systems.
The system employs an embedded fit between the protective cap and the connecting pipe. The stepped shape of the protective cap creates axial limiting, and the elastic deformation characteristics of PE material, combined with stainless steel ferrules and support components, disperse vibration energy and prevent direct impact on the weak areas of the ferrule and connector body.
It effectively improves the operational stability of copper pipes, enhances the sealing effect, reduces the risk of rupture caused by vibration, and improves the reliability and sealing performance of the system.
