ppr pipe with fiber glass

ppr pipe with fiber glass   As a kind of three-layer composite pipe, fiber/PP-Rcomposite pipe is a improver of normal PP-R pipe. Its inner and out layer is made of PP-R,which ensures the pipe hygienic when used for water suppluing. The fiberglass as min-layer greatly improves the strength of such pipes.     Greatly reduced linear expansion coefficient , 70% less than ordinary PP-R pipe, close to that of the sable composite pipes.     High strength and stability of dimension. It can bear 25% more pressure than PP-R under   the same condition.     Improve resistant to impulse under low temperature.     Excellent resistant to high temperature. It can be used in 90 for long term.     Socket fusion connection with PP-R fittings, credable and convenient.
