1) Healthful, innocuous, the production belong to green manufature of building materials, smooth inner layer without clogging
2) High temperature and pressure resisitant; The water temperature that transport by the piping can reach 95 when working under the long term consecutive working stress.
3) Hot-melting method when pipe and fiiting are the same material,
4) Heat preservation and energy saving; Coefficent of heat passage of piping just as one of two hundred as metallic conduit
5) Lightweight: Easily transport
6) The woking of the piping is very long; Its working life can reach at least 50 years under normal use
7) Anticorrosion, anti-encumbrance
