The difference between PVC pipe and ppr pipe


The difference between the PPR pipe and the PVC pipe is […]

The difference between the PPR pipe and the PVC pipe is based on the thickness of the pipe diameter, but the essentials of this identification must be experienced. First of all, be familiar with the environment of the pipe, at least have to have an impression. In this case, if you look at the pipe for a long time, you know how big the specification is.

1. Color difference: The materials used in the PPR pipe have toughness, and the good quality is bright, and the other is light yellow, and the poor quality is more chaotic. The PVC pipe is milky white, the material is hard and brittle, and the cross section has no light, but its appearance is bright.

2. Wall thickness difference: PPR and PVC pipe diameter are the same, the biggest difference is in the pipe wall thickness, PPR pipe thickness, PVC pipe wall is thin.

3. PPR pipe has the advantages of light weight, good corrosion resistance, no dirt and long service life. Moreover, the PPR pipe is safe and non-toxic and can be used in hot and cold water pipes as well as in drinking water systems. The maximum temperature of the PPR pipe can work in 90 degrees, working in 70 degrees, the service life can reach more than 50 years, and at normal temperature, its service life is more than 100 years. PPR pipe installation is very convenient, because PPR has good welding performance, whether it is heat welding or welding machine, it is very convenient. Moreover, the material after the PPR pipe is broken can be recycled, and can also be used for secondary use in the production of pipes and pipes. The PVC pipe cannot be recycled for the second use.

PVC (full name Poly Vinyl Chloride), the main component is polyvinyl chloride, and other ingredients to enhance its heat resistance, toughness, ductility and so on. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive.

Which is better for PPR pipes and PVC pipes?

PPR pipe is better. However, the scope of application is different and the characteristics are different. If it is only used for waterway renovation of cold water pipes, etc., from the quality point of view, it is definitely better for PPR pipes. But there is one point that everyone should pay attention to. There are many PPR pipes that will read: Unknown. It cannot be said that it is installed outdoors, under the sun, if the PPR pipe is installed outdoors, it must be changed once every two years, otherwise it will breed bacteria and the service life will be greatly shortened. It is not as good as PVC.

Ppr pipe is the most widely used in domestic or engineering water supply pipes.
