Wire Wound Finned Tubes

unraj Industries Exports wire wound Fin Tubes or Turbulators made of loops of wire wound helically on a central rod or tube and soldered to the inner surface of the tube. The internal turbulators are made of stainless steels, copper and galvanized steel wire. Sunraj make wire wound turbulators for tubes of inner diameter as low as 8 mm. There being no limit on higher diameters and lengths.
Wire wound turbulators are excellent tube heat transfer enhancement devices that increase the tube side heat transfer coefficient several fold at not too high pressure losses. Wire wound fin tubes for use in air cooled oil coolers are provided with internal fins selected from wide variations in configuration. We also manufacture double pipe wire wound fin tubes for use in refrigerated air dryers and heat exchangers for viscous and small streams.

Wire wound fin tubes can withstand temperature up to 180ºC with standard solder wire. However for high temperature application it can withstand temperature up to 290ºC. This is with the use of special silver content solder wire.
Wire wounded tubes can be manufactured by using various base tube material such as Carbon Steel, Copper, Cupro—Nickel, Brass and Alu. / Adm. Brass, Stainless Steel with fins of Copper, SS 304, SS 316, C.S & G.I
