Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, in particular to a large-diameter polyethylene-blended chlorinated polyethylene multi-wound structural wall composite pipe interface. Background Art
[0002] When rainwater needs to be discharged from a factory, multiple multi-wrap composite pipes are used for connection. The polyethylene-blended chlorinated polyethylene multi-wrap structural wall composite pipes have excellent anti-leakage performance and are suitable for drainage systems, ensuring that rainwater does not leak into the environment, keeping the factory dry and clean. They can treat sewage and rainwater stably for a long time and adapt to chemical media and pollutants that may exist in the factory area. The large-diameter design enables it to effectively handle large amounts of rainwater discharge.
[0003] The existing multi-wrap composite pipes are connected by simply applying oily silicone glue to the fittings of the multi-wrap composite pipes, and no flanges are installed on the outer surface of the multi-wrap composite pipes. During the connection process, the outer side of the multi-wrap composite pipes is easily contaminated with dust. Relying solely on silicone glue to seal the connection point between the two pipes may not ensure complete sealing, especially under long-term use or external force, leakage may occur. Without the fixing effect of the flange, the pipes may only rely on the adhesion of silicone glue to connect, and this adhesion may not be sufficient to cope with the changes in internal pressure of the pipe and the impact of external force, resulting in unstable connection. Silicone glue may lose its adhesion over time, resulting in reduced connection strength, especially under long-term erosion of high temperature, low temperature or chemicals, the stability of the connection will further decrease. If there is a problem with the connection, it will be difficult to disassemble and replace the pipe without a flange, requiring more professional tools and skills. Without the protection of the flange, dust and other pollutants are easily accumulated on the outside of the pipe, and these pollutants may affect the effectiveness of the connection and the appearance of the pipe.
