Technical Field

[0002] Pipe joints are key components connecting various parts of a piping system. They are used to achieve sealed connections between different pipe sections, valves, and equipment, ensuring the safe and efficient transmission of fluids (water, gas, liquid, etc.). Their performance directly affects the reliability, durability, and safety of the piping system.

[0003] Traditional building pipe joints mostly use rigid threaded connections, which have the following drawbacks:
