High Efficiency Carbon Steel Boiler Sprial Fin Tube Heat Exchanger Compact Structure
Advantages
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 chemical industry and pressure vessel.The capacity of the unit used in the boiler is also increasing.At present, a number of professional manufacturers in China can produce high-frequency welding and brazing spiral fin tubes, and the production equipment and technology of fin tubes can be introduced, digested and absorbed to be developed, designed and manufactured by themselves, and the quality has met the requirements of advanced foreign standards .
Advantages of using finned tube:
1) the heat transfer area is increased in the effective space to improve the heat transfer effect.
2) reduce the space occupied by the heat transfer surface and reduce its volume, especially suitable for the quick loading boiler.
3) reduce equipment costs and improve equipment security.
4) the reduction of water side pressure drop reduces the operating cost.
5) the stiffness of the fin tube is increased, and the anti-seismic capability of the tube is improved.
Types
High frequency resistance welding spiral fin 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 fin 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.
Integral spiral fin tube
Integral spiral finned tube is using thick wall tube (tube billet) in medium frequency under the condition of continuous heating, make the pipes after squeeze squeeze, copper and a molding whole spiral finned tube, see the latest a method of manufacturing finned tube has been developed by a domestic company whole spiral finned dad and homemade integral fin tube manufacturing equipment have been applied for a patent.
