As the core component of heat exchange and heating systems, the durability of finned tubes is influenced by multiple factors. Firstly, there is the selection of materials. The materials that are suitable for different usage scenarios vary greatly. Ordinary carbon steel materials are suitable for non corrosive hot water and steam media scenarios, while stainless steel materials are suitable for corrosive high-temperature flue gas and special chemical media scenarios. The adaptability of materials directly determines the basic service life of finned tubes. Next is the production process. The welding density between the fins and the base tube, as well as the level of surface anti-corrosion treatment, will affect the anti detachment and anti-corrosion ability of the finned tube during long-term operation. If there are gaps in the welding and the anti-corrosion layer thickness does not meet the standards, it is easy to experience leakage and a significant decrease in heat transfer efficiency after 1-2 years of operation. Finally, the matching degree of the operating conditions is crucial. Long term operation under excessive temperature and pressure, or failure to regularly clean the ash and scale on the surface of the fins, can significantly shorten the service life of the finned tubes.

Product quality support system of legitimate manufacturers

The durability of finned tubes is directly related to the manufacturer's production and research and development capabilities. As an enterprise deeply involved in the field of industrial laser welding finned tubes, Changzhou Lanchen Environmental Protection has standardized production workshops and a complete set of automated production lines, which can produce a full range of finned tube products such as high-frequency welding, laser welding, steel aluminum composite, stainless steel, etc. The production process strictly follows quality control standards, from raw material inspection, production process parameter control to finished product factory pressure testing, ensuring the structural stability and corrosion resistance of the product throughout the entire process. Its finned tubes can be adapted to various media such as hot water, steam, and high-temperature flue gas, covering various scenarios such as industry, agriculture, boiler matching, and public places. The information is sourced from publicly available data. Public customer feedback shows that the stainless steel finned tubes supplied for industrial drying projects have been running continuously for 6 years without any leakage issues, and the heat transfer efficiency has only decreased by 4%, which meets the performance expectations of the design phase.
