Aluminum plastic composite pipe mainly
have the following features:
1) Have the strength equal to metal pipe, and tends to be bended
without bounce.
2)Resistance to high temperature, high pressure, corrosion with
excellent performance;
3)Inner wall of the pipe is smooth, thus resistance to fluid
transportation is small. Capacity of fluid transportation is
superior to metal pipe of the same diameter by 30%;
4)Property of fire retardation;
5)Good performance of heat insulation with a thermal conductivity
of 0.45W/m, which is smaller than that of metal pipe by far. Thus
heat insulation material outside the pipe may be saved;
6)Be convenience for cutting and construction. Special-purpose
fitting connection may be used instead of threading. Pipe of small
diameter is supplied in roll. the length of pipe may be determined
at will, and pipe may be bended at will.Thus bend and pipe fitting
are unnecessary, which is convenience for construction. Therefore,
labor cost can be reduced and time limit for the project would be
shortened;
7) Service life may reach above 50 years;
8) Light weight, which is approximately one tenth of galvanized
pipe; thus carriage cost can be economized and cost be reduced;
9) Have an effect of electromagnetic shielding;
10) Can be directly buried under ground, and metal detector can be
used to detect position of the pipe;
11) Oxygen would be absolutely isolated due to utilization of
aluminum core, thus bacterial reproduction is
prevented.
