Finned Tubes

Corrugated Form

The flat fin is corrugated as it is wrapped onto the tube. The corrugation induces turbulence, which improves heat transfer in gases with poor thermal conductivity such as flue gas.

Fin Materials

Carbon Steel

Maximum Operating Temperature

150 – 360 °C

Tube Dimensions

16 – 60.30 mm

L Form

The fin is pre-formed and then tension-wound onto the tube. The L form footprint grips the tube tightly and delivers high efficiency.

Fin Materials

Carbon Steel, Copper, Aluminium

Maximum Operating Temperature

130 – 360 °C

Tube Dimensions

17 – 60.30 mm

KL Form

The pre-formed fin with a knurled footprint is mechanically locked onto the tube, giving a strengthened bond and high thermal conductivity.

Fin Materials

Aluminium, Copper

Maximum Operating Temperature

260 °C

Tube Dimensions

15.88 – 50.80 mm

G Form

The fin is embedded into a helical groove machined into the tube wall. Preferred at high temperatures and under continuous thermal cycling.

Fin Materials

Aluminium, Copper

Maximum Operating Temperature

400 °C

Tube Dimensions

17 – 60.30 mm

Laser Welded Form

The fin profile is joined to the tube surface by high-precision laser welding, creating a metallurgical bond for maximum heat transfer.

Fin Materials

Alloy Steel, Stainless Steel, Carbon Steel

Maximum Operating Temperature

700 °C

Tube Dimensions

17 – 60.30 mm
