1) Aluminum-plastic pipe takes the welding aluminum alloy pipe as the middle layer; The inner and outer layer is coextrusion PE plastic.
2) Each layer forms composite pipe with adhesive layer by thermal-heat adhesive, five layers structure is made with one-step method coextrusion, combines the advantages of metal pipe and plastic pipe.
3) Aluminum-plastic pipe has high withstanding pressure, capability of anti-breaking.
4) With strong distortion capability of plasticity, bend optionally in some radial range without bounce.
5) Light mass, on same flow diameter, aluminum-plastic composite pipe is 1/3 of that of copper pipe, 1/15 of that of galvanized iron pipe.
6) Smooth inner wall, no scale deposit, the flow is more than 30% of that of the same metal pipe.
7) With some elasticity to weaken the water hammer phenomena during water supplying, cancel the pressure impaction and noise of fluid.
8) Thermal conductivity is 0.45W/m. K, about 1/100 of that of steel pipe, it owns good performance of heat preservation.
9) Coefficient of thermal expansion is 2.5 x 10-5m/m. K, only 1/8 of that of PE pipe, to a great extent, it is the same as that of aluminum material.
10) With fine anti-flaming performance and electromagnetic screen performance.
11) Low cold shortness temperature, ultraviolet ray proof, strong capability of heat ageing, long service life.
12) Anti corrosion property: Be able to proof the corrosion of acid, alkali and salt, may transport kinds of corrosive liquid.
13) Can be laid at the length of ten meters, even hundreds of meters, so it can reduce many joints.
14) Bended optionally that it can reduce elbows as well.
15) The inner layer of aluminum-pipe is hygienic PE material, heavy metal stabilizer included. 16) Lead is not put in during processing, it has no toxicity but anti corrosion, no scale deposit and grow germs.
17) Cold and hot water pipe system.
18) Inner layer of aluminum-plastic pipe is smooth, no rust or scale deposit, the flow is more than 30% of that of metal pipe.
19) Can be installed by passing the beam column directly, it also can be embedded in the wall and concrete, if it needs to be detected, a simple metal probe can find.
20) Aluminum-plastic composite pipe is quite suitable for cold and hot water pipe system in the industrial and civil construction.
