Serrated Spiral Boiler Fin Tube Carbon Steel / Stainless Steel No Ash Accumulation
Spiral 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.
Serrated spiral finned tube is a special-shaped extended surface developed on the basis of spiral finned tube. Its manufacturing process is similar to that of high-frequency welded spiral finned tube, but the difference is that the gap of the strip must be cut before winding the serrated spiral finned tube.When winding, the cut part is separated naturally, forming a gear shape.On high frequency welding spiral fin hobbing winding technology not only simplifies greatly reduced (deformation), has combined with tight, high strength, thermal shock and mechanical shock, thermal performance is good, small flow loss, strong corrosion resistance performance, and has considerable diffusion surface, in cold and hot condition for a long time is not easy to deformation, long working life, also because of the destruction of flow boundary layer and intensified heat transfer.This serrated fin has been widely used in air conditioners and boiler economizers.
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.
6.Convenient ash removal, and noash accumulation.

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).
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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
