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

Accompanied by the continuous development trend of plastic piping commodities, now more and more varieties of products on the market, the performance of the strike, slowly replacing the cement drainage pipe and so on in the early days. In the water supply pipe industry, PE water supply pipe fittings and PPR water supply pipe are the application of high frequency of goods, the same is to the electrofusion fittings drainage pipe, then what are the differences between the two? 　　

PE to the pipe fittings and PPR to the difference between the specific performance of the following levels:

1, manufacturing raw materials are not the same PE to the pipe is made of high-pressure polyethylene raw materials, while the PPR pipe is a copolymer made of polypropylene. 　　

2, performance is not the same PE pipe ductility than PPR pipe, cold resistance is higher than PPR, on the contrary, PPR heat resistance is stronger than PE. Less than zero degree natural environment with PE for power supply, higher than 50 degrees of boiling water with PPR, room temperature water supply and drainage can be used in place of each other. 　　

3, PE siphon pipe fittings connection is not the same PPR water supply pipe connection with hot melt connection and flange connection, PE water supply pipe fittings connection with hot melt connection, electrofusion fittings connection, bearing insertion type flexible connection, flange connection and steel-plastic articulation connector connection, a large number of connection methods.      　　

4, the scope of application is not the same PPR pipe is generally used for small pipes, PE water supply pipe is generally used for large and medium-sized drainage equipment, PPR is generally used for drinking water for small and medium-sized home improvement; PPR pipe can be set up openly and darkly, PE pipe is suitable for darkly, openly raw materials are very easy to brittle. 　　

5, the price is not the same PE pipe price compared to PPR pipe project cost-effective, but also suffered manufacturers and model specifications of the hazards of the actual must be specifically investigated. 　　

6, product standards are not the same PE water pipe product standards is GB/T13663-2000, PPR water pipe product standards is GB/T5836.1-1992. In addition to the above, PE water pipe and PPR water pipe in the welding welding, environmental health level and its specifications specifications and so on there will be some differences in application, but also according to the actual needs of the Model specifications to the appropriate selection.
