1、 Difference between PE water pipe and PPR water pipe in sanitation
PE water pipe and PPR water pipe are almost the same in terms of health and safety. What matters is whether the raw materials used by the enterprise meet the requirements, rather than the difference between the two products. All qualified PE water pipes and PPR water pipe products must be subject to sanitary inspection (except fake and shoddy products). Saying that PE pipes are more hygienic and safe than PPR pipes is also a deception to consumers. Therefore, there is no difference in safety between the two pipelines.
2、 Modulus of elasticity
The elastic modulus of PPR water pipe is 850mpa. PE water pipe belongs to medium density polyethylene, and the elastic modulus is only about 550MPa. It has good flexibility and insufficient stiffness. It is used in the field of building water supply, with poor straightness, easy bending, easy deformation and unsightly pipeline.
3、 Thermal conductivity
The thermal conductivity of PPR water pipe is 0.24 and that of PE water pipe is 0.42, which is nearly twice as high. If it is used in floor heating, this is its strength. Good heat dissipation means better heat radiation effect, but it is its disadvantage in hot water pipe. Good heat dissipation, large heat loss, higher surface temperature of pipe and easy to be hot.
PPR pipe and PE pipe, which of the two drinking water pipes is better, there is always no correct answer. This mainly depends on the application occasions. The pipes used will be different in different occasions.
However, in life, one thing needs to be paid attention to is that no matter what kind of pipe you choose, you should choose a regular manufacturer to buy it. Especially when selecting PPR water pipes, it is particularly important to select regular manufacturers. Because there are a lot of fake PPR pipes in the market, we need to choose formal sales channels when selecting them.
