We offer spiral fin tubes. Fins are basically external surfaces on tube for increasing the surface area of the bare tube, resulting in a compact heat exchanger. Our spiral finned tubes are made under high mechanical tension bonding process, in which fin material is helically wound over the tube to get maximum contact of tube and fins end are brazed welded to core tube. Therefore it achieves highest efficiency and withstands high internal pressure. These tubes are used for heat transfer i.e. Cooling, heating of water, steam, air, gases, oils and many other vapors, fluids etc. These tubes are used in finned tube heat exchangers, steam radiators, autoclaves, condensers, dryers, ovens, furnaces, air heaters, oil coolers, after coolers, air compressors and in many other heat transfer equipments. Material - fin strip material = galvanized iron, stainless steel. Tube material = m.s, s.s.

The extruded fin is formed from an outer aluminum tube with a large wall thickness (muff), which is aligned over an inner base tube. The two tubes are pushed through three arbors with rotating discs that literally squeeze or extrude the aluminum fins up and out of the muff material in a spiral shape in one operation. Thus, provides an external surface on tube for increasing the surface area of the bare tube, resulting in a compact heat exchanger. These tubes are used for heat transfer i.e. Cooling, heating of water, steam, air, gases, oils and many other vapors, fluids etc. These tubes are used in finned tube heat exchangers, steam radiators, autoclaves, condensers, dryers, ovens, furnaces, air heaters, oil coolers, after coolers, air compressors and in many other heat transfer equipments. Advantages – 1.easy to clean with a high-pressure water jet without deforming the fins. 2.the tube is not mechanically stretched to adhere to the fins. 3.uniform and reliable heat transfer. 4.no galvanic corrosion between the tube and fins. 5.the fins are vibration resistant. 6.perfectly suited to industrial applications. 7.unequalled qualityprice ratio for demanding applications. 8.excellent mechanical resistance. Material - •fin material – aluminium (1070; 1060; 1050); copper. •tube material – m.s, s.s, aluminium, copper.

This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. The fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube. maximum working temperature - 285° c. Atmospheric corrosion resistance - excellent. Mechanical resistance - excellent. Fin materials - aluminium. Tube materials - no theoratical limit.

Fin tubes provides an external surface on tube for increasing the surface area of the bare tube, resulting in a compact heat exchanger. Whether rough service, high temperatures, or corrosive environment, our fin tubes are a great option for heat exchanger applications. dimentions - 1. Length of tube = upto 20 feet. 2. Outer diameter of finned tube = upto 88mm 3. Fin height = upto = 16 mm 4. Fins per inch = 8,9. Common uses heat transfer equipment including heat exchangers, boilers, economizers, super heaters, fired heaters, hrsg, waste heat recovery systems, water evaporators and more…
