Three-layer PP-R pipe production line/PPR pipe extrusion line/three-layer pipe extrusion machine:

The introduction to three-layer PPR pipe production line:

Three-layer co-extruded PP-R pipe for ABC or ABA form has reinforced glass fiber PP-R in the middle layer. And the production line adopts three-layer co-extruded molds with specific design spiral through three-layer co-extrusion technology, so that the intermediate reinforced glass fibers are arranged according to a certain rule and can be mixed with the inner and outer PP-R (or PP-B) as a whole to achieve enhancement. Therefore it significantly overcomes the overhanging phenomenon in pure PP-R pipe installation, reducing the coefficient of linear expansion of the pipe. Compared with pure PP-R pipe, three-layer PP-R pipe has the properties of saving materials, low cost and strong competition, etc. Pipes scope from φ20 ~ φ110mm. The pipe production line can produce single ordinary PPR pipe, which also can produce PP pipe, PE gas water pipe, PERT floor heating pipes and so on in place of molds.
