Detailed PAP Composite Pipe Description
Features:
a) Aluminum - plastic pipe takes the welding aluminum alloy pipe as the
middle layer, the inner and outer layer is coextrusion PE plastic
b) 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
c) Aluminum - plastic pipe has high withstanding pressure, capability
of anti - breaking
d) With strong distortion capability of plasticity, bend optionally in some
radial range without bounce
e) 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
f) Smooth inner wall, no scale deposit, the flow is more than 30% of
that of the same metal pipe
g) With some elasticity to weaken the water hammer phenomena during
water supplying, cancel the pressure impaction and noise of fluid
h) Thermal conductivity is 0.45W / m. k, about 1 / 100 of that of steel pipe,
it owns good performance of heat preservation
i) 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
j) With fine anti - flaming performance and electromagnetic screen
performance
k) Low cold shortness temperature, strong
capability of heat ageing, ultraviolet ray proof, long service life
l) Anti corrosion property: be able to to proof the corrosion of acid,
alkali and salt, may transport kinds of corrosive liquid
m) Can be laid at the length of ten meters, even hundreds of meters,
so it can reduce many joints
n) Bended optionally that it can reduce elbows as well
o) The inner layer of aluminum - pipe is hygienic PE material, heavy
metal stabilizer included
p) Lead is not put in during processing, it has no toxicity but anti
corrosion, no scale deposit and grow germs
q) Cold and hot water pipe system
r) Inner layer of aluminum - plastic pipe is smooth, no rust an
scale deposit, the flow is more than 30% of that of metal pipe
s) Can be installed by passing the beam column directly, if it needs to be
detected,
it also can be embedded in the wall and concrete, a simple metal probe can find
t) Aluminum - plastic composite pipe is quite suitable for cold and hot
water pipe system in the industrial and civil construction
u) Floor heating pipe system: aluminum - plastic composite pipe
can bend, it can not subject to distort for
extrusion, but it is very solid, even if it is distorted, it wound not be broken, it can bend
without bounce for its length
v) Many joints can be reduced to avoid the flow speed being blocked
or penetrated, with wide application temperature range
( - 40~+82o)
w) Heating mode with high hygiene condition and application
standard, widely used in the abroad families, spreaded in our
country generally
x) Indoor fuel gas pipe system: aluminum pipe clamp with longitudinal
welding is in the middle of plastic, in order that aluminum - plastic
composite pipe can withstand high working pressure and gas
() permeability is zero
y) Long pipe, can reduce joints to avoid penetrating, it is reliable to use
for air (compression air, gas, ) transportation line
