Spiral fin tubes are high - performance heat - exchange components engineered to boost thermal efficiency across diverse
industrial and commercial scenarios. Their unique spiral - fin structure maximizes the heat - transfer surface area, enabling
rapid and effective heat exchange between media. Ideal for applications like heat exchangers, HVAC systems, and industrial cooling
units, these tubes deliver reliable performance in both high - and low - temperature environments.
Products Description
Spiral finned tube
Structural & Dimensional Parameters
Tube Diameter
We offer a flexible range of base tube diameters, from 12mm (small - scale precision applications) to 100mm+ (large - flow
industrial systems). Common sizes like 19mm, 25mm, and 38mm suit most standard heat - exchange setups, while custom diameters
address specialized flow and pressure needs.
Fin Pitch
The fin pitch (distance between adjacent fins) typically spans 1mm–8mm. A tighter pitch (e.g., 1mm–3mm) packs more fins per unit
length, enhancing surface area for high - density heat transfer. Wider pitches (4mm–8mm) reduce airflow resistance, ideal for low
- pressure or high - viscosity fluid systems.
Fin Height
Fin height (from the tube surface to the fin tip) ranges from 5mm–30mm. Taller fins (20mm–30mm) amplify heat - dissipation area,
suiting high - temperature applications (e.g., boiler economizers). Shorter fins (5mm–15mm) balance efficiency and compactness for
space - constrained designs (e.g., automotive radiators).

Material Options
Base Tube Materials
* Carbon Steel (e.g., Q235, ASTM A106): Cost - effective, with good thermal conductivity. Best for non - corrosive, moderate -
temperature environments (e.g., general industrial heating).
* Stainless Steel (e.g., 304, 316L): Superior corrosion resistance for aggressive media (acids, salts) or high - hygiene settings
(food processing, pharmaceuticals). Retains strength at elevated temperatures.
* Copper/Copper Alloys (e.g., C12200): Exceptional thermal conductivity (ideal for refrigeration, HVAC condensers). Suits low -
to - medium temperature, non - corrosive applications.
* Aluminum/Aluminum Alloys: Lightweight, corrosion - resistant, and cost - effective. Common in automotive cooling systems, air -
conditioning units.
Fin Materials
* Aluminum (1050, 6063): Dominant choice—lightweight, high thermal conductivity, and easy to form. Resists oxidation, ideal for
air - cooled systems (HVAC, radiators).
* Copper: Matches copper base tubes for maximum heat transfer (critical in refrigeration, cryogenics). Higher cost but unrivaled
performance in low - temperature applications.
* Stainless Steel: Paired with stainless - steel base tubes for extreme corrosion resistance (chemical plants, marine systems).
Compromises slightly on thermal conductivity for durability.
