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.
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.
