Који је погоднији за цев за воду за пиће:ППР против ПЕ?

PPR Pipes and PE Water Supply Pipes, both can be used as drinking water pipes. Међутим, many users are not very clear about the pros and cons of these two types of drinking water pipes. Следеће, we’ll delve into the characteristics and application scenarios of these two types of pipes.

In the practical application of drinking water pipes, PE pipes are often used as cold water pipes; PPR pipes can be used for both cold water pipes and hot water pipes. When it comes to hot water pipe applications, PPR pipes are clearly superior. Међутим, with the improvement of economic conditions, PPR hot water pipes have gradually been adopted in many engineering projects to replace the traditional design of separating hot and cold water, allowing for direct use of both hot and cold water.

ППР против ПЕ: Цomparison of Hygiene

There is no significant difference in hygiene and safety between PE pipes and PPR pipes. The key lies in whether the raw materials used by the enterprise meet the standards, not the difference between the two types of pipes themselves. All qualified PE and PPR pipe products must undergo strict hygiene tests to ensure the safety of consumers (excluding counterfeit and substandard products). Стога, there is no obvious difference between the two types of pipes in terms of safety.

ППР против ПЕ: Considerations of Elastic Мodulus

The elastic modulus of PPR pipes is 850MPa. In contrast, ПЕ цеви, as medium-density polyethylene, have an elastic modulus of about 550MPa, which is more flexible but less rigid. When used in building water supply, PE pipes have poor straightness and are prone to bending and deformation, which affects the overall aesthetic appearance of the pipeline.

ППР против ПЕ: Thermal Цonductivity

The thermal conductivity of PPR pipes is 0.24, while that of PE pipes is nearly double 0.42. This feature of PE pipes is an advantage as an under floor heating pipes, as good heat dissipation means better heat radiation effect. Међутим, in hot water pipe applications, this could be a drawback because fast heat dissipation leads to large heat loss, the surface temperature of the pipe rises, and there is a risk of burning hands.

When it comes to the choice of drinking water pipes, there is no absolute superiority or inferiority between PPR pipes and PE pipes. The key lies in the application scenario. But no matter which type of pipe you choose, it is crucial to make sure it comes from a reputable manufacturer, especially when choosing PPR pipes, as there are many counterfeit products on the market, choosing a reputable manufacturer is particularly important.
