This is due to the different PPR particles of raw materials. Therefore, Anhua water pipe is white and white butterfly is gray, which does not represent the quality grade of the product.
What are the components of PPR pipe other than water pipe parts?
There are four types of PPR pipe connectors commonly used, which are generally welded on water pipes:
1. Bundle joint: it is used to connect two pipes when the pipe is not long enough.
2. Elbow: divided into right angle bend and 45 bend. It is used when the water pipe needs a corner.
3. Tee: connect water pipes in three directions.
4. Reducer: the connector connecting two water pipes with different pipe diameters. The above-mentioned bundle joint, elbow and tee have corresponding reducer, which is rarely used in home decoration.
5. Inner wire and outer wire: used to connect faucets, water meters and other types of water pipes. Most of the home decoration uses inner wire parts. The inner and outer wire joints are more expensive, and a joint with wire is even more expensive than a meter of water pipe
6. Stop valve / ball valve: for opening and closing water flow
7. Bending: it is used when two water pipes intersect on the same plane but are not connected. • Plug: also known as 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 PPR water pipe connection technology?
The interface of PPR pipe adopts hot-melt technology, and the pipes are completely integrated together. Therefore, once the installation pressure test passes, there will be no water leakage, and the reliability is very high.
8. How to judge the quality of PPR water pipe?
1. First look at the appearance. The appearance of the high-quality pipe is smooth, the logo is complete, and the brand name is also on the accessories; Inferior products can't do this. Because 100 percent imported PPR raw materials are used for high-quality pipes and only part of PPR raw materials are used for low-quality pipes, there are great differences in performance between the two.
2. Toughness: PPR pipes with good quality have good toughness and can be easily bent into a circle without fracture, while inferior pipes are brittle and break immediately after bending.
3. Thermal expansion and cold contraction: good pipes can still maintain hardness at high water temperature, while poor pipes will be softened at 60 degree .
4. Service life: quality products are guaranteed for 50 years, while inferior products can only be guaranteed for 5-6 years.
9. How to prevent water pipe explosion?
PPR pipe is different from iron pipe. Workers should handle it gently during installation. If they throw the parts around at will, no small cracks can be found at that time. The above situation will occur when it is completely closed.
