 PPR pipe commonly used colors: 

 Commercially available PPR pipe in several colors, white, gray, green and curry color, why is there this difference is mainly caused by masterbatch added. General recommendation to buy white PPR pipe, because very few were blinded by the manufacturers to use recycled materials to produce PPR pipe, by adding the masterbatch to cover up the defects caused by impurities of raw materials. 

 PPR pipe installation recommendations: 

 General in hydropower transformation, the existing water mains will be replaced, home improvement companies and businesses to choose all the hot water pipes in the proposed renovation to install PPR pipe, even through the cold water pipe with hot water. Their argument is that the waterway transformation of the technical parameters of the hot water pipe is higher than the cold water pipe, and the small price difference between the hot water pipes. 

 Diameter PPR pipe diameter from 16mm to 160mm in home decoration used in 20mm, 25mm two (respectively, commonly known as the four in charge, in charge of six), four of them in charge to use some more. If the economy permits, we recommend an outside diameter of 25 mm pipe (commonly known as the six charge), especially the cold water inlet tube, because the modern family living highly concentrated, water control more and more, while the high probability of water, This will minimize the water pressure, water flow small disturbances. 

 PP-R pipe course of development 

 PP-R pipe known as the three types of polypropylene tubes, using the random copolymer polypropylene by extrusion into pipe fittings injection molding become. Europe in the early 1990s to develop a new type of plastic pipe products. PP-R is the gas copolymer to the late 1980s, about 5% PE in the molecular chain of PP random polymerization (random copolymer) and a new generation of pipe materials. It has good shock resistance and long-term creep properties. 

 PP-R and PP-C difference between 

 Previous period, the domestic market, PP-C pipe, fittings, installation methods and PP-R. Many people do not know PP-R and PP-C What is the difference, resulting in a lot of misunderstanding and confusion. International standards, polypropylene, hot and cold water pipes sub-PP-H, PP-B PP-R three PP-C. PP-C pipe on the market is actually PP-B pipe, the raw material is a block copolymer polypropylene Pipe Compound. PP-B pipe is a kind of hot and cold water pipes, the price is relatively cheap, its heat resistance, pressure resistance of PP-R gap. Conditions of use, such as: grading, design pressure 0.6MPadn25mm pipe, PP-R pipe wall thickness of 3.5mm, PP-B (PP-C) tube wall thickness to 5.1mm; design pressure 0.8MPadn25mm, PP-R pipe wall thickness of 4.2 mm, while the PP-B (PP-C) can not be used. Because the required wall thickness is too thick. Structure on the market size and PP-R pipe PP-C, use is much lower, not be confused with the PP-R pipe use, can not determine the conditions of use instead of PP-R pipe, PP-C pipe. Conditions of use that the design temperature of 70 ° C, the heating water.
