The technological transformation in the air conditioning industry, where stainless steel is replacing copper tubes, has progressed from proof of concept to large-scale application. The core driving force behind this trend stems from the combination of three factors: anxiety over resource security, comprehensive performance advantages, and the need for cost optimization. China's dependence on foreign copper resources has long exceeded 70%, while the annual copper consumption in the refrigeration and air conditioning industry accounts for nearly 15% of total industrial consumption, posing high supply chain risks. Stainless steel tubes excel in corrosion resistance, have a longer lifespan than copper tubes, and reduce refrigerant transmission resistance, thereby enhancing system energy efficiency. More importantly, stainless steel materials cost several times less than copper materials. In the context of fierce competition in the air conditioning industry, this cost reduction potential holds strong appeal for enterprises.
With the continuous rise in copper prices and increasing pressure on raw material costs, stainless steel tubes, as an alternative to copper tubes for connecting and refrigeration tubes in household and commercial air conditioning, are gradually becoming a new trend in the industry. Guangdong Hangao Technology Co., Ltd. has customized a stainless steel air conditioning tube production line specifically designed to replace copper tubes. This production line boasts advantages such as high efficiency, high precision, and intelligence, helping users reduce costs and increase efficiency, and enhancing the overall competitiveness of enterprises.
