In the last piece, we learned the great properties of PPR pipe. Besides, we learned the applications of it. More important, we learned 2 ways to distinguish the quality. This time let’s learn the other 3 methods.
The melting smell
We learned that the connection of PPR pipe is the hot melting. This makes it a seamless entirety. While it should be odourless during the connection of high quality pipe. Besides, there will not be terrible smell even when burning. However, there will be terrible smell or even toxic substance during the hot melt of bad quality pipe.
Coating on the copper fittings
In order to keep the water safe, PPR pipe fittings adopt brass material without any coating. While copper will speed the aging of PPR pipe. Thus some supplier will add a insulated coating outside the brass. But this will release large amount of metallic elements and cause second pollution to the water. Thus it has been eliminated over 20 years ago.
In stead, high quality PPR pipe adopts special DZR brass as the material. Compared with normal brass, it has better corrosion resistance. Besides, it’s also eco-friendly, which means it can work in the environment without pollution.
The size of fitting’s bore
Good fittings have larger bore, the screw thread is longer as well. Large bore means the low resistance inside the fitting. Thus the flow amount will be large. Besides, it can effectively prevent the scale. In another hand, long screw thread make the distance smaller. Thus the connection will be more stable.
These are the 5 points to choose a better PPR pipe. Hope this piece can help you on the household decoration. OrientFlex is a professional manufacturer for all kinds of hoses and pipes. Our products have been exported to 120 countries and won good reputation. Contact us now and get more information.
