There are some difference between copper pipe and PPR water pipe ,the detail information is following:
PPR pipe: As a new type of pipe material, PPR pipe has unique advantages. It can be used as both cold water pipe and hot water pipe. Because of its non-toxicity, light weight, pressure resistance and corrosion resistance, it is becoming a popular material.
PPR pipes are not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. The interface of PPR pipe adopts hot-melt technology, and the pipes are completely fused together. So once the pressure test is installed and passed, there will be no aging and water leakage phenomenon like aluminium-plastic pipe. PPR pipe is called “never scaling, never rusting, never leaking, green high-grade water supply material”.
Copper pipe: Copper pipe has the advantages of corrosion resistance and sterilization. It is the top grade in water pipe. There are three kinds of installation methods of copper pipe: jacket, welding and pressing. Like the installation of aluminium plastic pipe, jacket has the problem of aging and leakage for a long time. So in Shanghai and other places, most users of copper pipe installation adopt welding type. Welding is to weld joints together through oxygen, so that they can. Like PPR pipes, it never leaks. Pressure joint is the latest installation technology. There are fewer domestic manufacturers adopting this technology. This installation method requires special tools. It is simple to install and has the same anti-leakage performance as welding technology. It is the latest technology. One of the drawbacks of copper pipes is that they are expensive. Very few water supply systems in residential areas are copper pipes. I am afraid they can only be seen in export apartments and high-end villas. If you plan to change the water pipe and think the copper pipe is good, it is suggested that the welding interface should be adopted. If there is pressure connection, the copper pipe can be used for both cold and hot water pipes.
Copper pipe and PPR water pipe have their own advantages and disadvantages. They are very practical materials widely used in construction, machinery.
