Detailed Product Description
PP-R aluminum plastic composite pipes are consited of five layers. The middle layer is aluminum foil, connected with inner and outer PP-R layers through thermo welded adhesive.They have better properties than normal PP-R pipes.Such pipe is a kind of perfect combination of metal pipe and plastic pipe.
Greatly reduced linner expansion coefficient, only 1/4 of that of PP-R;
Improved resistant to impulse under low temperature and higher pressure;
100% oxygen tightness,can work under high temperature and higher pressure;
Easily detected by detector when embedded, owing to the metal layer;
Good performance of heat preservation and low heat conduction coefficient;
Smooth and sanitary, being good selection for drinkable water system;
Service life can last up to 50 years
