The relationship between pipe size and temperature is not very great. The only thing is that the water flow is a little larger, and when the valve is just opened, the hot water enters slowly when the thin pipe enters, and the hot water enters quickly when the thick pipe between. Insulation, but it is impossible to insulate the water in the pipe. If you have a water outlet at home, 16 is enough, 20 is better. , but it is not necessary to install 20. Many households use aluminum-plastic pipes, and most of them are 16 What is the inner diameter of 6 distribution pipe in mm?
It is generally 21.3mm, but because there are many types of water pipe materials, the thickness of each person's wall is different, so the specific inner diameter should be determined according to the specific inner diameter. thickness of the pipe wall. ByExample, for a 6-point water pipe with a wall thickness of 2.8mm, the inner diameter can be obtained by subtracting the outer diameter from the wall thickness and multiplying by 2.
< p>How to choose water pipes1. The quality of water pipes determines the quality of water
When purchasing water pipes, The first thing we should pay attention to is that it is a quality problem, as it has a huge impact on water quality. It is not recommended to use galvanized water pipes, because water pipes made of this material are prone to scale and rust on the pipe walls after prolonged use, which will lead to secondary pollution water and will harm our health. after drinking it. You can choose aluminum plastic or ppr water pipes. These two water pipes not only have good corrosion resistanceon, are not prone to scaling over time and are better able to ensure the safety of drinking water.
2. The construction of water pipes is a guarantee of durability
Good quality water pipes will be easier to install, but they must also have good technical quality and the quality of installation is very important. If the installation quality of the pipe is not up to standard, no matter how good the water pipe is, there will be many problems in its later use and the insurance factor will be greatly reduced, the quality of construction must therefore be paid for. Pay attention to.
3. Water pipe after-sales service
When many people buy water pipes, they will focus on the price, and some people will choose low-price water pipes, and the written price of water pipes Aspects related to commitments are simply ignores. It is very important to know that this commitment represents complete after-sales service. If there is no written commitment, it will be difficult to deal with subsequent issues.
