PPR pipe type is pure plastic pipe, good or wave of good?
There is no authentic fiberglass pipe in the market, and if the sandwich material is not good enough, it will cause the pipe to fall off, so the individual feels better.
For the people, each exit a new product will lead to a wave of upsurge, Double Decker is just a product of speculation, in fact, the core material has not PPR pure material expensive, but the sandwich pipe instead of selling expensive. I think the trend is not a trend, like the stainless steel pipe, PPR pipe, after a long time will recover the original simplicity.
