Can PVC pipes and PVC pipe joints be used as hot water pipes?


PVC pipe and PVC pipe joint are easy to break and deform. In fact, it is a plastic tube, and the interface is usually glued. Because of its poor resistance to freezing and heat, it is difficult to use as a hot water pipe; strength is not suitable for the pressure requirements of water pipes, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire and sewage pipes.


Which material is suitable for hot water pipes?


The PPR tube is relatively better. The PPR tube is a new type of water pipe material that can be used both as a cold pipe and as a hot water pipe. Due to its non-toxic, light weight, pressure resistance and corrosion resistance, it is becoming a popular material. Also suitable for hot water pipes, even pure drinking water pipes. The interface of the PPR tube is made by hot melt technology, and the tubes are completely integrated together. Therefore, once the installation pressure test is passed, it will not exist as long as the aluminum-plastic tube and the PPR tube will not scale.
