Application of PPR pipe fittings as hot water pipe

PPR pipe fittings is not only used to PPR the only one kind of material, but the use of PPR material production of hot water pipe at the same time also used the PPR material used to produce cold water pipe.
For the PP material it is joined by 1%~4% as a random copolymer of ethylene (PPR) or a high rate of containing a large number of clamp copolymer (PP-B) ethylene material, the strength of PP usually increases with the increase of ethylene content. If the PPB materials used in the hot water pipe, in use after a period of time (usually family 2-3 years) you will find that the heat pipe can not restore the swelling phenomenon, bending deformation and pipeline, serious and may even lead to the occurrence of buried pipe wall arch cracking phenomenon. The use of life is far less than many manufacturers called 50 years of use of time. But for the VEKA PPR material softening, it is basically the use of temperature above 130 degrees C.
Generally speaking in the normal process of the use of the family is not the obvious phenomenon of bending deformation, so we can rest assured that the long-term use.
