Customized Rubber Insulated Air Conditioner Copper Aluminium conjunction Tube/Pipe Under the premise of not affecting the basic performance and reliability of air conditioning, the cost of copper-aluminum composite pipe is better than that of copper-connected pipe. When there was no large-scale use before, because the welding process between copper and aluminum was immature, the coating process of the heat shrink tube was also immature, which would lead to the processing cost being much higher than the material cost, and the use of copper and aluminum composite connection tubes was not worth the loss. Nowadays, with the tips of manufacturing process capability, the maturity and popularization of simple copper-aluminum welding and heat-shrink tube coating technology, the processing cost has been greatly reduced, and the advantage of material cost has been highlighted.
