Renovation of a new home, about the waterway, you will definitely use the PPR tube . Now there are many brands in the market. Do you know how to distinguish the quality? If you use improper products, it will not only cost a lot, but also affect your mood. But you don't have to worry, Jiuzhi Plastics Network will tell you the basics of home improvement PPR pipe, so you can identify the pros and cons of PPR pipe.
1. Material composition of PPR
The chemical name of PPR is random copolymerized polypropylene. It can be seen that its material is composed of polypropylene and the process is gas phase copolymerization, so it is composed of synthetic chemical materials. At present, the best PPR raw material supply on the market comes from Europe, and the second supplier is South Korea. Currently, there is no quality PPR raw material supplier in China. So, when choosing a PPR tube, ask, where is your PPR material coming from? Due to cost factors, the actual manufacturer chooses raw materials from Korea, but unscrupulous manufacturers will choose to recycle the scrap. So, look at the color and you know it.
2, the difference between PPR hot and cold water pipes
The wall thickness of the hot and cold water pipes is different, and the pressure that can be withstood is different. The cold water pipe is 16 kg and the hot water pipe is 20 kg. In terms of thermal conductivity, they are also different. Hot water pipes can pass cold water, and cold water pipes cannot pass hot water. Divided into cold and hot pipes, mainly because of the lower requirements of cold water pipes, so they can report lower prices. If economic conditions permit, it is best to buy hot water pipes.
3. Some characteristics of PPR
health
The material consists entirely of carbon and hydrogen, which is added without any toxic heavy metal salt additives.
Heat resistant, good insulation performance
The highest operating temperature can reach 95 degrees Celsius, its instantaneous temperature can reach 110 degrees Celsius, and the long-term use temperature is 70 degrees Celsius. It can be used as the hot water supply system pipe. The thermal conductivity is only one-two percent of the steel pipe, which has better thermal insulation performance. . PPR tubing has a service life of more than 50 years at rated service temperatures and pressures. The PPR tube, which has been used for 50 years, is achievable.
Convenient pipe connection
Due to the pipe and pipe fittings, the pipe fittings are made of uniform raw materials. The integrated hot-melt connecting pipe, pipe fittings, connecting parts and pipes are combined into a solid whole, and the strength is greater than the strength of the pipe itself, permanently eliminating the hidden danger of water leakage.
Green, recyclable
Production, construction, no pollution to the environment during use, and will not cause pollution problems. Production and construction waste can be recycled and reused, and can be directly used to reproduce pipes and fittings. However, since the waste must be attached with impure impurities, it is conceivable that the color of the produced material is certainly not pure.
4, the method of correctly distinguishing the advantages and disadvantages of PPR tube
A look: the quality of the PPR water pipe is soft and oily. The inferior PPR water pipe is mixed with inferior plastic or even lime powder. Its color is unnatural, and the cut section is dry and oil-free, so it feels like adding chalk ash.
Second touch: The inner and outer walls of the high-quality PPR water pipe are smooth and have no concave and convex cracks, and the inner wall of the inferior PPR water pipe has a rough surface.
Sancha: The quality of PPR pipes is heavier than that of inferior PPR pipes. Inferior PPR pipes are lighter than high quality. Because of the high quality PPR metal pipe fittings, most of them have three or more waterproof leaking grooves. Copper parts are longer in size and thicker in thickness, so they are heavier than inferior PPR tubes.
Four-burning: The high-quality PPR raw material is a hydrocarbon chain compound. When the flame temperature is higher than 800 degrees Celsius, under ideal combustion conditions and sufficient oxygen, only carbon dioxide and water vapor are released during combustion, and there should be no burning. Odor and residue, but inferior PPR pipes have odor and residue when burned due to the incorporation of inferior plastics and other impurities. The sheet can be cut from the PPR water tube and identified by burning with a lighter.
Finally, don't forget the quality of the pipe fittings. It is actually more important than the pipe. It is best to choose the brand-name products that everyone recognizes.
