PPR pipe is commonly used in home decoration, but its capacity is not small, such as water supply, hot water pipeline system, heating pipeline system and air conditioning pipeline. Project hot water also involves the use of PPR pipe, it is more stable, safe, easy to install, and cost-effective. Engineering hot water PPR pipe can also be hidden. When the concealed pipe passes through the wall, in order to ensure the safety, service life and convenient maintenance of the pipe, the metal sleeve can be set to ensure the installation of PPR pipe.
In the installation project, PPR pipe has the advantage of hot-melt connection. The pipes and fittings are welded by temperature heating, so that the water is not easy to leak, but the heating temperature and time need to be accurate and should not be too long. If the temperature is too high and lasts too long, the pipes and fittings will be damaged by hot melt. If the time is too short and the temperature is too low, the pipes and fittings will be unstable and easy to burst.
Nowadays, PPR pipeline is more and more popular in the society, involving water supply, sewage, irrigation, gas transmission and other uses. Because of its own advantages and characteristics, it can stand out in the pipeline Market and occupy a very important position.
PPR is a kind of random copolymerization polypropylene, which is prepared by random copolymerization of propylene monomer and a small amount of ethylene monomer under the action of heat, pressure and catalyst. Ethylene monomers are randomly distributed in the long chain of propylene, and ethylene monomers are generally controlled between 3-5%. The cold brittleness is determined by the ethylene content and the polymerization mode of ethylene and propylene. Therefore, in winter, the flexibility of PPR pipe will decrease, while the rigidity will increase and flatten. If the pipe is impacted by external force, the surface cracking of the pipe will be more serious.
Therefore, it is suggested that when we use or install PPR pipes in winter, we need to be more careful to prevent pipe collision and littering. Taking good care of pipelines is equal to taking good care of our own water consumption.
