Application In Dwelling Design And Construction For New Type Supply-drain Pipe Materials

In recently years ,Application of new type plastic supply-drain pipe material gets more and more wide spread ,It has great progress in our country for production and construction technique of many new type supply-drain pipe materials and component ,and relevant material type from zinc-planting-corrugated pipe and iron pipe become to UPVC,PP-R,PE-X,PB,PP-C and plastic-alumium ,ABS and so on.But because it is not spreading popularize and new type pipe in market emerge in an endless steam ,the selling market is not standard ,many pipe material has not standard temporary .How to choose suitable pipe materials that it is not only the ordinary use don't know but also relevant design and construction technician can not know comprehension.In this article ,through lab and engineering site trials that the physical data of new type pipe materials is corrected ,the results are as follow : (l)the expansion coefficient of new plastic pipe materials is more large than that of iron pipe .(2)new plastic pipe materials have different heat-resisting character and according to the water temperature to choose pipe materials ;(3)the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ;(4)probing into the press-resistance character of new plastic pipe materials.Through researching ,it can provide reference for designing materials .New type pipe materials are understood and knew thoroughly by the vast users ,which can promote application and dissemination for new type building pipe materials.
