PVC-U Pipes For Water Supply
   Product performance
    1、Is it poison , have secondary pollution not to flow PVC-U to be pipe hygiene nonpoisonous to have , form the dirt , cause the algae in the course of using kind and other microorganism, will not produce the secondary pollution to water quality.
   
    2、Flow obstruction little PVC-U in charge of inboard wall to be smooth , flow obstruction to be little , its rough rate is 0.008-0.009, input water ability relatively casting the iron pipe to improve by 25%, the concrete is in charge of improving by 50%.
   
    3、Traditional pipe service life is 20-30 years to have long performance life, the pipe service life of PVC-U is not lower than 50.
    4、Help PVC-U in charge of proportion lightly , ship only for steel , 1/5 casting the iron pipe, 1/3 of the concrete. Pipe account for greatly with the specification , with black 1/4 which cast the iron pipe of length ball, 1/10 of the concrete. So, load and unload it conveniently, can lower traffic expense is 1/2-1/3.
   
   
    5、Machinery have 23 of good more performance tensile strength when less than 45Mpa , resist person who press to be good , is it can break to 1/2 of external diameter to keep.
    6、It is convenient to join, install simply and conveniently because PVC-U is in charge of the quality lightly and exchanging the connection , and having certain toughness, so it is simple to install relieving oneself, compared with other pipes, the more complicated the pipeline system is, the more outstanding advantage what PVC-U is managed is.
   
    7、It is in charge of maintaining 30% that the expenses are in charge of only in order to cast the iron pipe or the concrete maintaining easy PVC-U.
