AI Technical Summary
When connecting composite pipes, especially in the sealing connection at the pipe ends, due to the inherent characteristics of its multi-layer composite structure, it is impossible to achieve sufficient fusion bonding. This causes the medium to seep between the reinforcing layer and the plastic layer, resulting in "water leakage" and "bulging" phenomena, which weaken the sealing reliability and long-term pressure bearing capacity of the connection structure.
By setting a seal between the inner and outer plastic layers of the composite pipe, and using a melting method to connect the first and second sealing sections to the seal, an effective seal is formed, avoiding the water seepage path of the reinforcing layer, realizing the fusion of the plastic layers, and forming a leak-free seal.
It achieves a stable and reliable connection of composite pipes, avoids water leakage in the pipeline, and is low in cost, easy to install, highly safe, and has good sealing performance.
