What is the difference between PE water supply fittings and PPR water supply pipes

With the continuous development trend of plastic pipe products, there are more and more products on the market today, and the performance is worth talking about, slowly replacing the earlier cement drainage pipes and so on. In the water supply pipeline industry, PE water supply pipe fittings and PPR water supply pipe are all commodities with higher application frequency, as well as drainage pipes for electric fusion pipe fittings, so what are the differences between the two? The difference between PE water supply pipe fittings and PPR water supply pipe is specific in the following levels: 1, the production and manufacturing of raw materials are not the same PE water supply pipe is made of high-pressure polyethylene raw materials, and PPR pipe is made of copolymer polypropylene. 2, the performance of the different PE pipe ductility than PPR pipe, cold resistance is higher than PPR, on the contrary, PPR heat resistance is stronger than PE. PE is used for power supply in the natural environment of less than zero degrees, PPR is used for boiling water of more than 50 degrees, and water supply and drainage can be substituted for each other at normal temperature. 3. The connection method of PE siphon parts on the same layer is different. The connection method of PPR water supply pipe is hot melt connection and flange connection. The connection method of PE water supply pipe fittings is hot melt connection, electric melt pipe connection, socket flexible connection, flange connection and steel-plastic connection head connection, and the connection method is large. 4, the scope of application is not the same PPR pipe is generally used for small tubes, PE water supply pipe is generally used for more large and medium-sized drainage equipment, PPR is generally used for drinking water small and medium-sized home decoration; PPR pipe can be open and hidden, PE pipe is suitable for dark, open raw materials are very easy to embrittlement. 5, the price is not the same PE pipe price compared with the engineering cost of PPR pipe is more cost-effective, but it also suffers from the harm of manufacturers and model specifications, and the actual must be investigated. 6, the product standard is not the same PE water supply pipe product standard is GB/T136
