1,Introduction:

As a kind of high quality and high-performace pipe, the product has a construction of five layers. The inside and ousite layers are made of PPR, tightly bonded with PP-based adhesive to the mid-layer of aluminum core,which is well welded in an overlapping way. Such pipe is a kind of perfect combination of metal pipe and plastic pipe.

2,Advantages

A, Greatly reduced linear expansion coefficient, only 1/4 of that of PPR which means the composite pipes have stable dimensions.
B, 100% oxygen tightness, suitable for heating system;
C, Improved resistant to impulse under low temperature, resistant to UV-rays;
D, Working under higher temperature and higher pressure for cool and hot water system;
E, Easily detected by detector when embedded, owing to the metal layer;
F, Good performance of heat preservation and low heat conduction coefficient of 1.45W/M.K;
G, Smooth and sanitary, being good selection for drinkable water system.
