PPR pipe is most commonly used in home decoration, but its ability is not so small, such as water supply, hot water pipeline system, heating pipeline system and air conditioning pipeline.
Engineering hot water also involves the use of PPR pipeline, which has the advantages of more stability, safety, convenient installation and high cost performance. The PPR pipe for hot water in the project can also be concealed. When the concealed laying passes through the wall, in order to ensure the safety of the pipe, ensure the service life of the pipe and facilitate maintenance, a metal sleeve can be set to ensure the installation of PPR pipe.
In the installation project, the most advantage of PPR pipe lies in the hot-melt connection. The temperature heating is used to weld the pipes and fittings. This effect will not easily detect the leakage of water, but the heating temperature time needs to be accurate and can not be too long and too long. If the time is too long and the temperature is too high, the pipes and fittings will be damaged by hot-melt. If the time is too short and the temperature is too low, If the pipes and fittings are not hot fused, they will not be firm and easy to burst.
Now PPR pipe is becoming more and more popular in society, involving water supply, sewage, irrigation, gas transmission and other purposes. Because of its own advantages and characteristics, geese and chickens can stand in the pipe market, occupying a very important position.
PPR is random copolymerized polypropylene, which is formed by random copolymerization of propylene monomer and a small amount of ethylene monomer under the action of heating, pressure and catalyst. Ethylene monomer is randomly distributed in the long chain of propylene, in which ethylene monomer is generally controlled between 3-5 percent . Its cold brittleness is determined by ethylene content and polymerization mode of ethylene and propylene. Therefore, in winter, the flexibility of PPR tube will be reduced in low temperature environment, while the rigidity will be enhanced and become flat. If the pipe is impacted by external force, the surface cracking of the pipe will be worse.
Therefore, when we use or install PPR pipes in winter, we need to be more careful to prevent pipes from collision and littering. Taking good care of pipes is equivalent to taking good care of our own household water.
