Why PPR pipe is the first choice for home decoration

 Galvanized pipe 

Most of the old houses are galvanized pipes. Now the iron pipes for gas and heating are galvanized pipes. However, developed countries have banned galvanized pipes as drinking water pipes since 1960s and 1970s, while China has banned them since 2000.

Main advantages: good strength, good weather resistance, very suitable for gas and heating pipes.

Main disadvantages: galvanized pipe as a water pipe, after a few years of use, a large number of rust scale inside the pipe, the outflow of yellow water not only pollutes the sanitary ware, but also mixed with bacteria growing on the unsmooth inner wall.

 PVC-U 

In fact, it is a kind of plastic pipe. The joint is generally bonded with glue. The frost resistance and heat resistance of PVC-U pipe are not good, so it is difficult to be used as hot water pipe. Because of its low strength, it can not be applied to the pressure bearing requirements of water pipe, so it is not suitable for cold water pipe. Therefore, in most cases, PVC pipe is suitable for wire pipe and sewage pipe.

In addition, this year's scientific and technological circles have found that phthalide, a chemical additive that can make PVC softer, can affect human kidney, liver and testis, cause cancer, damage the human body's functional reconstruction system and affect development.

 Copper pipe 

It is generally used to connect by clamping and pressing. Due to the concealed installation in China, if the sealing ring is damaged and leaking, the maintenance is very inconvenient.

Main advantages: high temperature resistance, sanitation

Main disadvantages: due to its material, the inner wall of copper pipe is smooth, easy to scale and produce copper green. Therefore, in the case of long-term use of copper pipe, the water flow of water pipe will be reduced, affecting the daily use. At the same time, the price is expensive, the construction is difficult, and the water quality is required.

 Stainless steel pipe 

Its performance is similar to that of copper tube, and its heat insulation is better than that of copper tube

Main advantages: good strength, good weather resistance

Main disadvantages: there are two ways to understand stainless steel pipe, one is welding, but the welding will easily cause the water pipe to rust, which will reduce the service life of the water pipe; the other is the way of clamping pressure. However, under high temperature conditions, the heat conduction is fast and the heat dissipation is fast. Therefore, in the process of the contact between the pipe and the wall, the service life of wallpaper and paint will be affected by high temperature.

At the same time, in order to prevent water leakage, a gasket will be added at the joint of stainless steel pipe. However, in winter, due to the different temperature and the different thermal expansion coefficient between the gasket and the stainless steel pipe, it is easy to cause water leakage.

 PPR 

As a new type of water pipe material, PPR pipe has unique advantages. It can be used as cold water pipe and hot water pipe. Due to its non-toxic, light weight, pressure resistance and corrosion resistance, PPR pipe is becoming a popular material. PPR pipe is not only suitable for cold water pipe, but also suitable for hot water pipe, and even pure drinking water pipe.

The interface of PPR pipe adopts hot-melt technology, and the pipes are fully integrated together. Therefore, once the installation and pressure test is passed, there will be no aging and water leakage like the aluminum plastic pipe for a long time, and the PPR pipe will not have the phenomenon of scaling and rust.
