Stainless steel inner finned tube - * * is just that powerful

　　Stainless steel inner finned tube and spiral finned tube are a type of heat transfer element. The heat transfer area of stainless steel finned tubes is several to tens of times that of light tubes. Stainless steel finned tubes reduce the resistance of downward movement, reduce metal consumption, and improve the economy and operational reliability of heat exchange equipment. Nowadays, stainless steel finned tubes are widely used in various boilers. The domestically produced Cooper cooler has been proven through years of practice that the characteristics of the stainless steel finned tube condenser can fully meet the working conditions of the machine, and all goals have reached or exceeded those of the original product. Fit the fins onto the outer surface of the tube by interference fit. Using an early method of processing finned tubes. Due to the simplicity of the skill set, low skill requirements, low equipment prices, and ease of repair, many factories in Hangzhou still choose oxygen generator coolers. This skill is a labor-intensive skill program that is suitable for the funding and skill requirements of typical small factories or township enterprises.

　　A manual set is called a craft set. The method of using things and relying on human strength to press the fins in one by one has limited pressing force on the fins, resulting in a small interference fit and easy loosening of the fins. Mechanical fin assembly is carried out on a fin assembly machine because the pressing of the fins relies on mechanical impact force or liquid pressure, and the pressing force is large. Therefore, a larger interference fit can be selected. The connection strength between fins and tubes is high and not easy to loosen. The production rate of the Qingjiang Petrochemical oil cooler set is high, but the noise is loud, the safety is poor, and the working conditions of the workers are poor. Although hydraulic transmission does not have the above-mentioned problems, the equipment quotation is relatively expensive, and the skill requirements for maintenance personnel are high, resulting in lower productivity.
