Application of laser welding finned tube in boiler and wall mounted furnace
Although it is more advanced in product quality and production automation compared with inlaying and brazing methods, it is difficult to weld through the root of high frequency welded finned tube and the root has wrinkles and other factors, resulting in the high-frequency welded finned tube in heat transfer efficiency and easy to prevent ash deposition. In view of the above reasons and in response to the national policy on energy conservation and emission reduction.
It is easy for secondary processing and can be directly used for coil and elbow. Small heat affected zone and small metallographic change make it possible to process small diameter finned tube. The materials used for heat exchange tubes and condensing tubes should have heat transfer performance, better corrosion resistance, erosion resistance and wear resistance, as well as good strength, stiffness and plasticity, which are easy to process and manufacture.
Finned tube coils are commonly used for gas-liquid exchange. Heat transfer on the gas side is usually much lower than on the liquid side, and heat sinks are required on the gas side. The outer fins of the tube may be normal on a single tube, or maybe transverse, spiral, or longitudinal. Longitudinal fins are commonly used in a double tube or shell heat exchangers without baffles. A fluid may be a gas or a viscous liquid. Our finned tube coil products range from small applications to large commercial and industrial projects.
