We produce laser welded finned tubes and high-frequency welding finned tubes. And it is widely used for civil wall-hung boilers, industrial boilers, etc.
There are many types of finned tubes. Although high-frequency welding finned tubes are more advanced in terms of product quality and production automation compared with inlay and brazing methods. Due to its factors such as difficulty in welding the root and wrinkles at the root cause many shortcomings in heat exchange efficiency and fouling prevention. By comparison, the laser-welded finned tube is the most advanced product of irreplaceable advantages. It has a high penetration rate, can prevent crevice corrosion, prolong service life and reduce heat transfer resistance. Breaking through material restrictions. And it can use different materials for processing, saving material costs, and easy for secondary processing.
The disadvantage of laser welding is that the processing time is longer and the output will be limited. Therefore, we still maintain a high-frequency welding production line, which can provide fast and large numbers of finned tubes with low cost, and still has a high market share in general industrial applications.
