PPR tube common knowledge solution
10 common knowledge solutions for PPR tube:
1. What is the difference between PPR pipe, PPR copper pipe and PPR aluminum pipe? What kind of family is it used for?
PP-R pipe is also called three-type polypropylene pipe. The raw material molecules are only carbon and hydrogen. There are no harmful and toxic elements. It is hygienic and reliable. It is not only used for hot and cold water pipes, but also for pure drinking water systems. The inner layer of the PPR copper tube is a copper surface covered with PPR. The surface of the PPR aluminum covered tube is covered with a layer of PPR.
2. What is the general life of the water pipe?
The normal water temperature is about 60 degrees, and the service life can reach more than 50 years.
3. What is the scientific name of the PPR water pipe?
The PPR pipe is officially called the random copolymer polypropylene pipe, which is the most widely used water supply pipe in the home improvement project.
4. How is the PPR water pipe divided between the cold water pipe and the hot water pipe?
The PPR pipe is divided into a cold water pipe and a hot water pipe. The difference is that the cold water pipe has a blue marking line and the hot water pipe is a red wire.
5. Why is the PPR water pipe color different?
This is due to the difference in raw material PPR particles. Therefore, the Pilsa water pipe is white, and the white butterfly is gray, which does not represent the quality level of the product.
6. What are the components of the PPR pipe in addition to the water pipe?
There are 4 kinds of commonly used PPR pipe joints, which are generally welded on water pipes:
1. Bunch section: When the pipe is not long enough, connect the two pipes.
2. Elbow: divided into right angle bend and 45 bend, when the water pipe needs a corner.
3. Three-way: Connect the water pipes in three directions.
4. Size head: connecting the two water pipes with different pipe diameters. The above mentioned bundles, elbows and tees have corresponding heads, which are rarely used in home decoration.
5. Inner wire and outer wire: connect the faucet, water meter and other types of water pipes. Most of the home decoration uses the inner wire. The inner wire and outer wire joints are more expensive, and a wire joint is even more expensive than a one meter water pipe.
6. As close to the valve / ball valve: open and close water flow
7. Winding bend: Two water pipes are used when they intersect in the same plane without docking. • Plug: It is also called bulkhead. After the water pipe is installed, it is used to temporarily close the water outlet and remove it when the faucet is installed.
7. What are the characteristics of the connection technology of PPR water pipes?
The interface of the PPR pipe adopts the hot melt technology, and the pipes are completely fused together, so once the installation pressure test is passed, the water will never leak again, and the reliability is extremely high.
8. How to judge the quality of PPR water pipes?
1. First look at the appearance, the quality of the pipe is smooth, the logo is complete, and the brand name is also available on the accessories; inferior products can not do this. Because high-quality pipes use 100% imported PPR raw materials, inferior pipes use only some PPR raw materials, and the two have great differences in performance.
2. Resilience: Good quality PPR pipe has good toughness, can be easily bent into one circle without breaking, and inferior tube is brittle, and one bend is broken.
3. Thermal expansion and contraction: a good water pipe can maintain hardness at high water temperature, while a poor quality pipe is softened at 60 degrees water temperature.
4. Service life: quality product warranty for 50 years, inferior products can only be 5-6 years.
9. How to prevent water pipe explosion?
The PPR pipe is different from the iron pipe. When the worker installs it, it should be handled lightly. If you throw it away and throw it away, you can't find any small cracks. If it is completely closed, the above situation will occur.
