ASME Standard Spiral Type Boiler Fin Tube Carbon Steel / Stainless Steel Heat Transfer Use
Sprial fin tube description
Spiral finned tube is efficient heat transfer parts for boiler with spiral fin,it's heat transfer area is several times of bare tubes.Which can improve heat transfer, reduce flow resistance and material consumption.
Spiral finned tubes are now widely used in various boilers.It can be manufactured in a variety of ways,including high frequency resistance welding spiral finned tube,brazing spiral finned tube and intergral spiral finned tube.
Types
High frequency resistance welding spira finned tube
High-frequency resistance welding spiral fin tube is in be weldment import high power high frequency current, by using the current welding joint contact area and adjacent area to produce the resistance of the hot melt welding contact surface to melt or half of the plastic state, and then give the appropriate pressure welding contact surface, thus complete finned tube welding work.
Brazing spiral finned tube
Brazing spiral fin tube is a kind of solder which is filled with a solder with a melting point lower than that of the solder, and then heated the solder welding temperature. When the solder does not melt, the fusion well of solder is wetted and welded, and the solder joint is formed by spreading out the contact point of the solder piece, so as to complete the welding of spiral fin tube.
Advantages
1. Increase heat transfer area in effective space to improve heat transfer effect.
2. Reduce the space taken up by heat surface,reduce volume,especially suitbale for quick loading boilers.
3. Reduce equipment costs and increase equipment safety.
4. Reduce operation costs.
5. Improve the anti-seismic capability of tubes as increase finned tube stifness.

Applications
The fin tubes are mainly used in heating(gas-fired boilers, condensing boilers, flue gas condensers), in mechanical and automotive engineering(oil coolers, mine coolers, air coolers for diesel engines), in chemical engineering(gas coolers and heater, process cooler), in power plants(air cooler, cooling tower), and in nuclear engineering(uranium enrichment plants).
