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.
