How to choose ppr pipes?
The real PPR pipes should meet the standard Din8077/8088 -- The performance of pseudo-PPR pipes and fittings will not reach the above criteria. It should be noted that the pseudo-PPR pipe life is only 1--5 years, while the real life of PPR pipes are more than 50 years.
How to choose ppr pipes?
PPR pipes widely used in industrial and residential buildings in the life, health and drinking water supply and hot water heating. PPR hot and cold water pipes divided two kinds. Cold water pipe wall is thin, hot pipe wall thick. so a lot of good in terms of fracture resistance properties of hot water pipes, hot water pipes price also more expensive than cold water pipe of some. Many manufacturers to be safe, hot and cold water, regardless of the construction process, cracking, improve the safety factor.
1. Good flexibility PPR pipes, fittings and easily deformed by squeezing, even if the deformation is not broken, and greatly reduce the amount of joint use.
2. The corrosion-resistant waterproof junction PR pipes, fittings resistant to the chemical nature of the chemical elements in the water erosion, while the smooth inner surface prevents the formation waters
3. The high temperature, high pressure PR pipe, pipe fittings withstand water at room temperature at a pressure of 45 kg / cm, the tube deformation temperature of 112 degrees Celsius
4. Long life PPR pipes, fittings and strong anti-aging, the normal role of the mission more than 50 years.
5. Quick and easy construction PPR pipes and fittings become very flexible construction makes quick and easy connection (socket connection with hot melt machine), safe and reliable.
6. Affordable As the construction is simple, and there is no contradiction between the impact and other projects, shorten the construction period, the construction cost than copper save 60%, with excellent economy.
Therefore, be careful when consumers buy, be sure to choose the right, large manufacturers, quality assurance of the pipe, the other in the installation, but also pay attention to some points, might listen to expert advice.
Expert advice: to let through professional training of skilled workers to operate. At the same time, the process is also very important. Shall be in accordance with the principle of smooth vertical and horizontal, on the basis of the ground the room is larger than the pipe diameter of the slotted deep grooves, and then laying PPR pipes, followed by one order of hot melt connection. After all PPR interface uses hot-melt technology to integrate together to be more than 24 hours of pressure testing, if the field environment allows pressure test time can be longer. When we are sure there is no leakage of water seepage phenomenon, and then landfilled.
