Product Description

ASTM B280 0.2mm-3mm Wall Thickness Refrigeration Air Conditioner Connecting Copper Pipe

The main uses of copper pipes are:

(1) In air conditioners, refrigerators and freezers, used as heat exchange devices, connecting pipes and measuring instruments;

(2) Water pipes, gas pipes and oil pipes;

(3) Cable tube;

(4) Hollow wire;

(5) Other aspects, such as the main tube used for external fins, high-efficiency heat transfer tubes with internal threads, and heat pipes for computer CPU and large-scale integrated circuits to dissipate heat.

Different uses have great differences in the quality requirements of copper coils. For example, copper tubes used in refrigeration units are small in size and thin in wall thickness. They must go through a series of processes such as bending, flaring, and welding to make the final product. , The pipe shall not have cracks and leaks during processing and use, and the working surface should have good thermal conductivity. The wall thickness of copper water pipes and gas is slightly thicker than that of air-conditioning pipes, and no leakage is still the basic requirement. At the same time, the consistency of state and size is also very important, so that it can be connected with ferrules during construction. The cable tube must ensure its good electrical conductivity, and the length of a single tube is an extremely important indicator, which should reach several kilometers. The hollow wire is a pipe with a heavy section. Whether it is used in motor manufacturing or electric furnace, its conductivity and length are still the basic requirements.
