Water pipe is a kind of building materials that will be used when decorating the house. Many owners do not know how to buy the proper water pipe. There are many different colors of water pipe. When purchasing, we don't know which color to buy. Among them, the more common color is red line and blue line
There are two colors on PPR water pipe, namely red and blue drainage ditch. National standard: PPR tube red or blue color bar, not less than 2. (so pro, there is only one color bar PPR tube, use with caution
PPR is the abbreviation of random copolymerization polypropylene, which is close to transparent. If the color is not added, there will be light transmission in the process of use, thus breeding moss or bacteria. Therefore, in the national standard, PPR water pipe must have "opaque test". In order to meet the requirements, each family adds "Color Masterbatch" in the production process. In this way, there are "white, gray, yellow, green, blue..." on the market PPR water pipe of equal color.
The PPR of the red bar means that the pipe wall thickness is large. Similarly, its long-term compressive strength at high temperature is higher.
In the national standard, the nominal pressure of PPR pipe with blue bar is 16 kg pressure. This nominal pressure is not burst pressure, but refers to the average stress that can be used for 50 years in 20 degrees for a long time.
The material of PPR water pipe will be marked as PP-R or polypropylene (type III polypropylene). However, if you write other words on it when purchasing water pipe, do not buy it.
The quality of the water pipe is related to the safety of our drinking water. If some poor quality materials are used, it will also have a bad impact on our health in the future.
High quality PPR water pipe, smooth surface texture, not rough. If it is a poor quality PPR water pipe, then it may add some impurities. If you feel it by hand, it will feel very rough or grainy. Then this kind of water pipe can not be purchased.
PPR water pipe, that is, type III polypropylene pipe, if it is of high quality, then there will be no obvious odor or irritant smell. Therefore, when we choose PPR water pipe, we can smell it to see if there is any peculiar smell. Drainage ditch
The same pipe diameter and wall thickness of the water pipe, high-quality PPR water pipe is lighter, more sensitive to the weight of the owners, in the purchase, you can compare.
The sound of high-quality PPR water pipe is relatively dull; but the sound of poor quality water pipe is relatively crisp. We need to pay attention to this point, and some people may reverse it.
We can take out the mobile phone, turn on the flashlight and irradiate it in the water pipe. Then we can see whether the water pipe is transparent through the outside. If the water pipe is transparent, we can't choose this kind of water pipe for surface installation.
Some people think that using green PPR pipes looks more environmentally friendly. In fact, this color really doesn't matter. In general, it is recommended that you choose white water pipes. There is no need to have green ones.
In addition, if you really want to buy non white water pipe, then you should also look at the color of the water pipe. If the color is very bright, it may not be a good water pipe, so you need to choose carefully.
PPR pipe is divided into cold water pipe and hot water pipe. The difference is that the cold water pipe has a blue marking line, while the hot water pipe is a red line. In addition, the PPR pipe has signs such as s5s4s3.2s2.5. Generally, SS4 is cold water pipe with thin wall thickness, while s3.2s2.5 is hot water pipe with relatively thick wall thickness.
About the color of PPR tube: there are mainly several colors of white gray green on the market. In general, recycled plastic can't be white, so many people often think that white is. In fact, this view is more one-sided. On the contrary, the situation of unqualified white PPR tube in dark test is more. With the development of technology, color is not the standard to distinguish PPR tube.
The article has given you a detailed analysis of PPR water pipe red line and blue line is what all the introduction, hope to be helpful to you. PPR water pipe is a kind of building materials that we often use when we transform water and electricity. In addition to paying attention to the line color on the PPR water pipe, we should also pay attention to some purchasing skills.
