Longitudinal Finned Tubes

tsi league image image of longitudinal finned tubes

Heat Ex Tube Limited finned tubes (or finned pipe) are produced by resistance welding fins in diametrically opposite pairs. The way channels are welded on the external surface of the tube makes them highly efficient.

They are formed from a U channel of material, with the base being pressure rolled and spot welded to the tube or pipe. The number of fins must always be a multiple of four.

We supply longitudinal finned tubes for:

  • double pipe heat exchangers
  • multi-tube heat exchangers
  • fire rated heaters
  • gas coolers
  • tank heaters

And we are able to accommodate the requirements of various industries, including oil, power, chemical, and petrochemical.

All our finned tubes can be manufactured from most weldable or brazable materials. The finned pipe is supplied in straight lengths or U bent form.
