 Matilda Pipe Industry Co., Ltd. is located in Jiangbei Water City, close to the economic Museum speed entrance, convenient transportation and superior environment. Professional development, PPR piping systems of production and sales of environmentally friendly high-tech plastic pipe production enterprises, mainly: "Sun and Moon" brand new environmentally friendly PP-R cold and hot water pipes and fittings, PE-RT floor heating pipe fittings, annual production capacity of over 2000 tons, PPR pipe production enterprises in North China and the surrounding areas. 

 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 hot and cold water, the price is cheaper, its resistance?? Barrel, light weight, corrosion resistance, no scaling, so that f?? Conditions of use classification 2, the design pressure 0.6MPadn25mm pipe, PP- R pipe wall thickness of 3.5mm, PP-B (PP-C), tube wall thickness to 5.1mm; located???? PP-R raw material molecules only carbon, hydrogen, no harmful toxic elements, health, not only for hot and cold water pipes, can also be used for pure drinking water system. 

 2, energy-saving insulation. PP-R pipe thermal conductivity 0.21w/mk steel is only 1/200. 

 3, good heat resistance. PP-R pipe, Vicat softening point of 131.5 ° C The maximum operating temperature of up to 95 ° C, to meet the building so that the hot water system in the drainage specification??% A long life characteristics, but also has the following main characteristics: 

 1, non-toxic, health. Of PP-R materials elements only carbon, hydrogen, no harmful toxic elements are present, health, not only for hot and cold water pipes can also be used for pure drinking water systems. 

 2, energy-saving insulation. PP-R pipe thermal conductivity 0.21w/mk steel is only 1/200. 

 3, good heat resistance. PP-R pipe, Vicat softening point of 131.5 ° C The maximum operating temperature up to 95 ℃, to meet the building to the use of hot water system in the drainage specification requirements. 

 4, long service life. PP-R pipe operating temperature of 70 ° C, the working pressure (PN) 1.OMPa conditions, service life of up to 50 years (provided that the pipe must be more than S3.2 and S2.5 series)
