Ppr pipeline, as the main body of water supply circulation system, plays a vital role in our daily life. In the previous PPR pipeline market, there were only pure PPR pipelines; Then, in order to break through the linear expansion performance of PPR Pipes, a five-layer PPR steady-state composite tube with aluminum layer in the middle was developed; Later, with the enhancement of the competitiveness of the water pipe market, various ppr water pipe manufacturers have taken the path of innovation and research. They have not only made breakthroughs in appearance, but also made changes in the structure of PPR Pipes. They innovatively developed double-layer PPR Pipes. What is the difference between double-layer ppr pipeline and single-layer ppr pipeline? Next, IFAN will unveil the mystery of the double-layer ppr pipeline.
The difference between double-layer PPR pipe and single-layer PPR pipe is that the raw material is ppr, the model and specification are the same, and the PPR pipe is sanitary, clean, free of scale, and has a long service life. The difference between double-layer PPR pipe and single-layer PPR pipe:
1. The visual impact of the appearance is different. The double-layer ppr water pipe has two colors from the inside to the outside. There are also three layers of color water pipes on the market, which are diverse in color and can meet the demand of pursuing individuality. The single-layer ppr water pipe is pure color from the inside to the outside, each has its own advantages.
2. The commissioning methods of production equipment are different. The double-layer PPR pipe has two delivery ports for production and feeding, which can place raw materials of different colors and be extruded at the same time, while the single-layer PPR pipe has only one delivery port for feeding.
To sum up, there is no difference between double-layer ppr tube and single-layer ppr tube in application. Of course, in real life, some PPR pipe manufacturers will cheat when producing multi-layer PPR pipes, replacing the middle layer with PPR substitute raw materials, such as PPB or PPH, and claiming that the PPR products have the function of impact resistance or frost resistance, and the thermal resistance and long-term creep of PPB materials are very poor, which is not suitable for hot water circulation, while the low temperature performance of PPH is poor, which is not suitable for construction at low temperature. Therefore, The mechanical properties of both PPB and PPH do not meet the relevant production indicators of PPR pipes required by the state. Strictly speaking, this variant PPR pipe is not a real PPR pipe.
