As a domestic water pipeline, the most essential point is sanitation. The metal conduit that uses originally, because resists corrosion, but rusting performance is bad, long-term accumulation scale, have a bigger effect on living water quality. Because of this, PP pipe is gradually instead of it, and you don't need to worry about being corroded. And the high and low-temperature bearing capacity is also excellent, although the pp pipe also has the possibility of freezing crack, under the low temperature of -20℃, it will be very safe to use, as long as the high-temperature working environment is not more than 70℃ is also very safe, as a domestic water pipeline is more than enough. In addition, the service life of the pp tube is very long, under the condition of normal use, basically doesn't have to worry about the need to change, but it is worth noting that the pp tube, after all, is a kind of plastic pipe, pp pipe strength and surface hardness is certainly not an as hard metal pipe, so pay more attention in the process of transportation, handling and installing.
