PPR hot and cold water pipe is the main difference between the pressure, the cold water pipe pressure is 1.6 or 1.0 MPa, hot water pipe pressure is 2.0 or 1.6 MPa. PPR cold water pipe is generally used as a water pipe, hot water pipe is generally used as a heating pipe, water heater can also be used for hot water pipes. If the cold water pipe used in the work of the larger pressure on the hot water pipe (such as heating pipe) is likely to cause wall erosion, but this is not absolute, some pipe cold water can also be used for hot water, but no matter How cold water pipe to do hot water pipe is not allowed, hot water pipe when the cold water pipe is possible.
Cold water pipes and hot water pipes to withstand different pressures, wall thickness is different, the price is different, hot water pipes than the cold pipe wall thickness, the price is more expensive. Hot water pipe marked with a red line, if the same specifications of the PPR pipe wall thickness can also distinguish between hot and cold water pipes. In addition, the hot and cold water is best to use a brand, as well as accessories, when the choice of those who choose bright color and oil texture of the pipe, the tube wall to be shiny, no cracks, the weight to choose some weight.
