Inner layer of stable PPR-AL Pipe is the common pipe extruded, after it is coated with aluminum foil, then coated by a PP-R out layer, the foil layer is sticking on plastic layer with hot-melt glue. It overcomes the defects of common PP-R pipes such as high expansion coefficient, bad anti tardily variation, very easy to deform.

Stable PPR-AL Pipe Production Line:Inner layer of stable PPR-AL Pipe is the common pipe extruded, after it is coated with aluminum foil, then coated by a PP-R out layer, the foil layer is sticking on plastic layer with hot-melt glue. It overcomes the defects of common PP-R pipes such as high expansion coefficient, bad anti tardily variation, very easy to deform.
Pipe Application:
1. Cold and hot water supply;
2. Pipe network for solar energy facility;
3. Caliduct, floor, wall-applied heating unit;
4. Snow melt unit in building in Norther zone;
5. Hot water circulation system;
6. Central air conditioning piping.
Processing :
Stable PPR-AL Pipe Production Line:Raw material+masterbatches → Mixing → vacuum feeding → material dryness → single screw extruder → spiral mould → calibrator → spray vacuum calibration tank → moisture blowing system → drying → Al plate unlocking → AL plate folding machine → gelatinizing extruder → outer layer extruder → co-extrusion mould → spray cooling water tank → spray-code printer → belt haul-off → no-dust cutter → pipe rack → finished product inspecting &packing
Technical Parameters Stable :
