ASME Stainless Steel Spiral Finned Tube For Heat Exchanger Carbon Neutral
Sprial fin tube description
The spiral finned tube is formed by welding the steel strip on the bare tube along the spiral track by high-frequency welding method. Through fin material winding process and high frequency welding, The spiral finned tube can make the fin and tube pressure melting as a whole, its contact thermal resistance is approximately 0 which can withstand the alternating thermal stress. No deformation after welding, so as not to weaken the bearing capacity of the base pipe, is conducive to heat transfer from the fin to the inner wall of the base pipe. The serpentine pipe wound by the sprial finned pipe (the elbow part has no finned) is composed of the tube group as the heating surface of the economizer, that is, the sprial finned economizer.
Spiral finned tube has been widely used in the heat recovery of coal economizer, air preheater and waste heat boiler, as well as heat exchange equipment in the chemical industry and pressure vessel. Our products can be modified according to our customers' needs and the situation.we design and manufacture safe, reliable and efficient spiral fin tubes.it has also completed stand-alone product quality assurance systems. Production of spiral fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
1. Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.
2. Fins are used to increase the effective surface area of heat exchanger tubing.
3. Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas, vapor to a gas, such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.
The fin tube heat transfer area is 8 times the light tube, high-efficiency heat exchange, more advanced than the other heat-exchange products.
Application: Boiler Economizer, Heat Exchange, Power Plant Waste Heat Boiler, Petrochemical Engineering.
