What Is The Explosion-Proof Performance Of The PPR pipe?

According to incomplete statistics, there are more than 200,000 disputes and complaints cases caused by the bursting of domestic water pipes every year. The main causes of water pipe bursting are: water pressure, ambient temperature, water temperature, unqualified raw materials, irregular production process and improper installation.

According to experts: "PPR Pipe is a random copolymer polypropylene, which is what we call type III polypropylene. It is obtained by random copolymerization of propylene monomer and a small amount of ethylene monomer under the action of heating, pressurization and catalyst. Therefore, the temperature and ambient temperature should not be too high or too low. Generally, the long-term over-water temperature of the hot water pipe should not exceed 75 °C. When it exceeds, there will be a "popcorn"-like blasting phenomenon; when the ambient temperature is lower than 0 °C, the pole It is prone to freeze-exposure of “linear” water pipes.

The ethylene monomer is randomly distributed into the long chain of propylene, wherein the ethylene monomer is generally controlled between 3-5%. The ethylene content and the polymerization mode of ethylene and propylene determine the brittleness of the PPR tube at low temperatures. The lower the temperature, the greater the brittleness of the pipe. In particular, the water in the pipe will freeze and cause a wave burst.
