PVC pipe fittings

a new drainage pipeline substitutes for castiron pipe

      INTRODUCTON:

      PVC-U pipes for drainage buildings is made of polyvinyl chloride resin as the main raw material,adding appropriate auxiliaries, getting by mixing,extruding,sizing,colding,cutting etc.many possesses,and presently substitute for the traditional castiron pipe of buildings,which is vastly applied in drainage system of building projects.

      ADVANTAGES:

compared with the traditional castiron pipes

1,The density of PVC pipe is the 1/5-1/6 of that of castiron pipe, light weight,convenient for transporting,stevedoring,and installing,which sharply lowering the construction cost, as well as lowering the weightbearing of buildings.

2,NO rusting,the serving life is 4 times than that of the castiron pipe;

3,The inner wall of pipe is very smooth,the roughness coefficient is only 0.009,micro hydraulic resistance,

4,Easy Installing:low construction cost

5,Tiny coefficient of linear expansion,0.07mm/m.°c,little affected the defections;
