1. PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages. It is hygienic and non-toxic. It can be used as either a cold water pipe or a hot water pipe.
Advantages: moderate price, stable performance, heat resistance and insulation, corrosion resistance, smooth inner wall without scaling, safe and reliable pipeline system without penetration, and service life of up to 50 years.
2. UPVC pipe: It is actually a kind of plastic pipe. The interfaces are usually glued. UPVC pipes have poor frost resistance and heat resistance. Therefore, hot and cold water pipes are rarely used, and PVC pipes are suitable for electrical wire pipes and sewage pipes.
The scientific and technological community has discovered that the chemical additive phthalein, which can make PVC softer, has a great impact on the kidneys, liver, and testicles in the human body. It can cause cancer and kidney damage, destroy the human body's functional reconstruction system, and affect development. (You can only use cold water, not hot water, and it is easy to become brittle in winter).
3. Galvanized pipes: As water pipes, after being used for several years, a large amount of rust will occur in the pipes. The yellow water flowing out not only pollutes the sanitary ware, but is also mixed with bacteria that breed on the rough inner wall. The rust causes heavy metal content in the water. If it is too high, it will seriously endanger human health (the country has issued regulations prohibiting its use as drinking water pipes.
Advantages: complete varieties and many matching pipe fittings.
Disadvantages: It is eliminated and prohibited from use by the country. Products are easy to corrode and rust, causing poor water flow and easily causing water pollution.

How to select domestic water pipes:
1. . Go to regular building materials markets to purchase them as needed, so that the quality of the water pipes is more guaranteed.
2. Check the surface of the water pipe to see if its appearance is smooth and even. You can touch it with your hand to see if it feels delicate; At the same time, check whether the water pipe is marked with the manufacturer's anti-counterfeiting mark. If not, it is best not to buy it.
Third, look at the color of the water pipe. High-quality stainless steel water pipes are generally silver-white and black. They have not been treated by acid and alkali passivation and are easy to scale. The color of high-quality PPR pipes is generally matte and milky white, and there will be no variegated particles in it. If the color of the water pipe is mixed with some variegated colors, it indicates the quality of the water pipe. Not good.
Four. Plastic pipes should smell like water pipes. If the water pipe has an irritating smell, it means that the quality of the water pipe is not good. A high-quality water pipe will not have an irritating smell.
