Cold and hot water piping system: The interior of the aluminum-plastic composite pipe is smooth, non-corrosive, and free of scale, and the flow rate is 30% larger than that of metal pipes. It is easy to bend, can be installed directly over beams and columns, can be buried in walls and concrete, and can be detected with a simple metal detector, so the pipe is very suitable for cold and hot water pipelines in industrial and civil buildings system use. Indoor gas pipeline system: The longitudinally welded aluminum pipe is sandwiched between plastics, so that the all-round pipe can withstand high working pressure, so that the gas (oxygen) permeability is zero, and the pipe length can reduce joints and avoid leakage, so this kind of pipe is suitable for It is safe and reliable for compressed air, gas, oxygen and other gas transmission lines. Solar air conditioning piping system: The aluminum-plastic composite pipe is not easy to frost, and has good thermal insulation, which improves the efficiency of solar energy and air conditioning systems.
