I.Features：
PEX-AL-PEX composite pipe is composite pipe of five layers, inside and outside layers of which are made of Cross-Linked (PEX), tightly bonded with melt adhesive to the mid-layer of aluminum core which is longitudinally welded in a butt-welded or overlap-welded way, this kind of pipe is the perfect union of metal and the plastic ones.
II.Specification:
Overlapped welding

Butt welding

III.Advantages:
1.Compared with the metal pipe, the composite pipe has the same strength, easy to bend, reluctant to retain former shape;
2.Super properties of high temperature, high pressure and corrosion resistance;
3.Smooth inner surface of the pipe reduces resistance to the fluids. The ability to conduct water is 30% more efficient;
4.Good property of heat preservation, heat conduction coefficient is 0.45W/m.k,which is much less than metal pipes and it can save insulation materials outside the pipe;
5.Easy to cut and install;
6.Life pan of the composite pipe is more than 50 years.
