2. The 2.ppr pipe is smooth, and can't touch other particles, so the pipeline resistance is small and the energy consumption is lower. Ppr pipes and fittings of the same model and material are connected and integrated into a perfect whole, which avoids the problem of water leakage.
3.ppr pipe has corrosion resistance, which solves the problem of traditional metal pipe rusting. The nonpolar material of ppr tube avoids reacting with other chemical elements in water. Ppr pipe will not scale when used.
4.ppr pipe is light in weight, which greatly reduces the construction difficulty. As a green environmental protection material, it will not pollute the external environment during production or construction. ? The above is the introduction of the advantages of ppr tube. Many users will choose PPR pipe as the domestic water transportation pipeline. Now the water pipes have been replaced by plastic pipes.
Extended data:
Adopt hot welding method, have special welding and cutting tools, and have high reliability. The price is also very economical. The thermal insulation performance is also very good, and the pipe wall is also very smooth! The general price is 4-8 yuan per meter.
Except the joint of inner and outer wires, PPR pipe is officially called random polypropylene pipe, which is the most widely used water supply pipe in home improvement project at present. The PP-R water pipe is made of polypropylene, and the pressure resistance of the pipe can be known by the wall thickness. The long-term service temperature of PPR tube is below 75 degrees, and the highest instantaneous temperature is 95 degrees.
75 degree long-term work can be used for 3 years, and 95 degree long-term work can be used 1000 hours. Generally, the maximum temperature of instant water heaters will not be higher than 65 degrees, positive displacement water heaters will reach 95 degrees, and solar water heaters can reach 100 degrees in summer. According to what water heater and pipeline to use; It is suggested that high-temperature resistant and high-density crosslinked polyethylene pipes be used, which are produced by domestic drinking water manufacturers.
