PPR-AL-PPR pipe size 20-110mm Applied for potable water pipeline system which are hygienic and non-toxic.The aluminum middle layer has a very low linear heat expansion coefficient.The pipe is not only rigid as metal pipe but isalso flexible and pressure-resistant.Corrosion resistance properties prevents encrustation build-up in the pipes thus enabling the free flow of water and eliminating rust that causes stains in tubs and basins.The pipe has high temperature and highpressure resistance and can work undercontinuous normal pressure with water temperature up to 95 degree.Heat preservation and energy saving properties greatly minimizes heat losses during hot water flow .The heatconduction coefficient is 1/200 of metal pipes.The pipes are lightweight and the specific gravity is 1/7 of metal pipes.The surface of the inner and outer layer of the pipe is smooth therefore reduces flow resistance.The pipes can be buried underground and are easily found with metal detectors.The hot melt connection machine is used to connect the pipes and fittings,which makes the installation convenient and reliable .the installation can be finished within a few seconds.The pipes have a long lifespan of up to 50 years or more under normal conditions.
