PP-R piping systems for hot and cold water piping construction system is an important one. Once appeared to promote domestic boom PP-R plastic pipe systems, but unfortunately, due to the interference of counterfeit products and substandard products, PP-R pipe market has not been very good car with a hose sustainable development, on the contrary gave the market left a "plastic pipe is not durable," the bad impression that a lot of the water piping system architects and developers and square plastic pipes are losing confidence. From a technical perspective, the destruction of substandard products happen for many reasons. On the one hand there is no use of qualified raw materials, plastic pipe in the early development of Chengdu car with a hose, practitioners understanding of the long-term performance and strength of raw or inadequately Jingmen car with a hose, the raw material for understanding the evaluation method is also not impressive enough; the other is connected to the system is a problem, because the modulus of PP-R pipe inside the plastic hose is relatively large, so the joints prone to excess stress, particularly in the steel-plastic transition fittings and hot water After an action period of time, the case of leakage will occur frequently. Metal hose connector is a modern industrial pipeline in a high quality flexible pipe. It mainly consists of MOLLET metal hose fittings bellows, nets and connector components. Its inner tube is a spiral or circular walled stainless steel bellows, bellows outer nets, is made of stainless steel wire or woven according to certain parameters. Connector or flange ends of the hose with the joint or mating pipe flange customers. Bellows hose is extremely thin-walled seamless or welded stainless steel pipe after all high-precision plastic processing forming. Because of the elastic properties of the bellows profile determines the hose has good flexibility and fatigue resistance, making it very easy to absorb deformation of cyclic loading various sports, especially the ability to compensate for the large amount of displacement in the piping system.
