HF Welded Helical Finned Tubes

hf welded helical finned page image

At Heat Ex Tube Limited we are proud to supply a wide range of high frequency helical high finned tubes - great for the petrochemical and power generation industry.

A continuous helical fin is attached to the base of the tube by high frequency electric resistance welding. The helical fins produce a homogeneous, clean, continuous bond for efficient heat flow and resistance to corrosion.

The high frequency helical high finned tubes can be used in:

  • boilers
  • coolers
  • economisers
  • fired heaters
  • furnaces
  • heat exchangers
  • heat pipes

HF welded tube sizes and materials

Usually a combination of carbon steel, low alloy steel, and stainless steel, we supply the helical finned tube, which can either be serrated (segregated) or solid.

  • Tube thickness depends on the fin thickness and tube OD. The minimum thickness for tubes with a solid fin is 2.13mm and 1.99mm for tubes with a serrated fin.
  • Fin height is dependent on the type of fin, tube OD, fin thickness and material. If it’s a solid fin it’s usually between 6.3mm and 31.8mm, whilst serrated fins are 12.7mm-38.1mm.
  • Fin thickness varies depending on the fin type, as well as the height of the fin and tube OD. The helical finned tube is usually between 1 fin/inch and 7 fins/inch.

We supply the helical finned tube in a wide range of sizes, including:

Tube OD: 25.4 / 31.8 / 38.1 / 50.8 / 63.5 and 76.0 mm

Pipe OD: 26.7 / 33.4 / 42.2 / 48.3 / 60.3 / 73.0 / 88.9 / 101.6 / 114.3 / 141.3 / 168.3 and 219.1 mm
