Description

Technical Field

[0001] The utility model relates to the technical field of composite water pipes, in particular to a high-pressure resistant composite water pipe. Background Art

[0002] A water pipe is an important tubular component used to transport water. It usually has good sealing properties and can transport water between two places. In a water plant, by laying a complete set of water pipes and matching facilities, water can be transported to every household for use, providing greater convenience for people and allowing them to enjoy clean water.

[0003] In addition, water pipes are also commonly used in other facilities, such as fire protection systems, highway maintenance systems and other structures. They play an important role in various major facilities and bring convenience to people's lives in all aspects.

[0004] Nowadays, water pipes are generally light in texture, low in density, and poor in high-pressure resistance. When the internal water flow rate is too high or the water pressure is too high, or when the external pressure is strong, the water pipes often cannot withstand the pressure, causing damage, and then water leaks out, causing property loss, and even causing a series of safety problems. The usual practice is to add metal tape to the outside of the water pipe to enhance the internal and external pressure-resistant structure. However, in actual use, it is often necessary to cut and segment the water pipe according to site needs. Since the metal reinforcement tape is wrapped around the pipe wall, it is difficult to cut the pipe, and it is difficult to connect the two water pipes well, and the actual use effect is poor.
