The choice of water pipe in the decoration material is still more important, this project is also a hidden project, if you choose a product with poor quality, it is very troublesome to repair it. The following Xiao Bian will introduce to you how to judge the quality of PPR water pipes and what materials are good for household water pipes.
How to judge the quality of PPR pipes
1. “Touchâ€: You can try out whether the texture is very delicate and whether the particles are even. We must know that there are more and more PPR pipe counterfeit products on the market, and there are mainly several colors in the market, that is, there are several colors of white gray green. Under normal circumstances, recycled plastics generally cannot make white, so many people White is often considered to be the best, in fact, this view is a bit wrong, to know that the current technology development is still relatively fast. It can be said that color is not a criterion for discriminating PPR tubes. If the tube is good or bad, if you just look at it, it will not solve the problem. If you touch it, the rough particles are likely to be mixed with other impurities.
2. "Smell": There is no smell. The main material of PPR pipe is polypropylene. In general, good quality pipes have no odor. Poor pipe has some strange smells, and it may be blended with polyethylene instead of polypropylene.
3. "Pinch": The PPR tube is quite hard. If you can easily deform the tube when you select the tube, you can see that this is definitely not a PPR tube.
4. "ç ¸": A good PPR pipe, in general, its "resilience" is good, too easy to smash it can be seen that this is not a good PPR pipe. However, the hardness is not equal to the flexibility, and we have no doubt about the PPR tube that cannot be broken. Because some unscrupulous manufacturers increase the hardness of the pipe by adding too many impurities such as calcium carbonate, if this is the case, the pipe is prone to embrittlement after a long time.
What material is good for household water pipes?
Galvanized iron pipe
This kind of product can be said to be the most popular product in the country. If it is in foreign countries, it is still a product of elimination. In fact, there is only one reason for not choosing this kind of product. This kind of galvanized iron pipe will cause corrosion and it will be used. Affecting water quality, it is easy to cause heavy metals in the water to exceed the standards and cause serious health problems. Although the price of such pipes is cheap, health cannot be guaranteed.
2. PVC pipe
PVC (polyvinyl chloride) plastic pipes are also modern synthetic material pipes. Relatively few people use this kind of water pipe. In general, because its strength can not be applied to the pressure requirements of water pipes, it is rarely used in water pipes. In most cases, this is more suitable for wire and sewage pipes.
3. PPR tube
PP-R water supply pipe This is currently the mainstream product, and this product is also a better material to self-made, use it is more secure, and it also has a 50-year warranty.
4. Copper tube
This kind of pipe is very expensive, and it can be said that it is not available to the general public. The price of this kind of pipe is also relatively high, and it has bactericidal and antibacterial properties and good hygienic properties. The coefficient of thermal conductivity is lower than that of copper tubes, and it also has excellent insulation properties, so it is more suitable for high-end residential.
5. Stainless steel tube
This is also a very good product, but unfortunately the material will be harder, and the price is relatively high compared to the price. This is easy to cause inconvenience, damage, and high probability of waste. Therefore, in the use of processing, this pipe is still relatively rare.
Summary: On how to judge the quality of PPR pipes and what materials are good for household water pipes, we introduce them here. Although PPR pipes are easy to use, there are too many counterfeit products on the market, so we must master their skills. OK, hope that the above introduction will help you.
