Three-layer PP-R pipe making machine/ three-layer pipe production line/PPR pipe extrusion machine:
Three-layer PP-R pipe extrusion plant is used for the production of glass fiber PP-R (referred to as FR / PP-R), adopting multi-layers co-extrusion through special processes and machines to produce high-performance pipes.

The finished pipe not only maintains its merits on the basis of original PP-R, but also has the following major features: the lower coefficient of linear expansion (only about 20 to 30% of the ordinary PP-R products); completely solving problems of plastic pipe stretching; enhancing pipe hardness to prevent its sagging; reducing the density and the number of fixed points; low cost; higher pressure rating; longer service life in ordinary tremor force; better resistance to high temperature; saving energy and reducing consumption, etc. FR / PP-R normal temperature can comes up to 95~ 100 ° C in the hot water system which not only improves the use of the temperature of the medium, but also reduces thickness of the insulation material.
