Double Fin Tubes
Timex Metals is a reliable Double Fin Tubes Manufacturer, which provides high-performance heat transfer solutions designed for vigorous industrial applications. These tubes have two continuous fins that enhance surface area, thus increasing thermal efficiency and saving energy in heat exchangers, boilers, and air coolers. Using modern technology in the manufacturing and close quality monitoring, every Double Fin Tube has improved bonding between the fins and the base tube, which means that it is of high mechanical strength and is resistant to corrosion.
Double Fin Tubes – Material, Grades & Dimensional / Weight Table

| Alloy Steel | ASTM A213 T11 | Double Helical Fin | 38.10 | 3.40 | 2 × 12 | 6 | 6.70 |
Double fin tubes achieve an extraordinary increment of their external surface area due to the use of two continuous fin layers, therefore they are ideal for places where more heat dissipation is necessary but there is a limited space of the equipment. As a result, this arrangement raises the ventilating interaction and heat emission to a great extent in comparison with the traditional ones, at the same time, it keeps the mechanical stability under the operating loads which are continuous. In a B2B business environment, the availability of precise tables referring to the material grade, fin geometry, and weight per meter gives buyers the possibility to compare the upgraded fin solutions with the Single Fin Tubes alternatives and to choose the most efficient option in terms of performance, load handling, and lifecycle cost control.
