Abstract: This article briefly introduced the current situation of connection technology and applications in steel wire mesh skeleton polyethylene composite pipes and also analyzed their technical developments in the middle- and high-pressure connection technology. Taking the water supply pipeline project in the Enshi mountain area of Hubei Province as a typical example, the successful application of this high-pressure connection technology was introduced. This project promoted the application of steel wire mesh skeleton polyethylene composite pipes in the construction of middle- and high-pressure pipelines.
