NEOTISS™ HPT Finned Tubes

NEOTISS™ HPT Finned Tubes

We provide NEOTISS™ HPT Finned Tubes, a low-finned tubular solution which yields numerous benefits for shell and tubes heat exchangers. NEOTISS™ HPT Finned Tubes is a low-finned tubular solution providing 2.5 to 3 times the external surface area of bare tubes. This yields numerous benefits for the heat transfer equipment: reduced capital cost for new equipment, reduced retrofitting cost for existing equipment, but also space, weight & structural savings. NEOTISS is a worldwide leader of low finned tubes in hard-to-form materials such as titanium, duplex steel, stainless steel and high nickel alloys.


NEOTISS™ HPT Low Finned Tubes are used in shell and tube heat exchangers for oil & gas applications, purified terephtalic acid (PTA) plants, liquefied natural gas (LNG) plants, petrochemical & chemical applications, air conditioning and refrigeration condensers and evaporators.
NEOTISS™ HPT Finned Tubes can be considered especially when:

  • Constructing with expensive materials.
  • Debottlenecking an existing exchanger.
  • Retrofitting or upgrading with new tube materials.
  • Meeting a stringent space or weight requirement.


  • Provides 2.5 to 3 times the external surface area of bare tubes. 
    This yields numerous benefits for heat transfer equipment.
  • Reduced capital cost for new equipment. 
    Enhanced heat exchange efficiency means less NEOTISS™ HPT Finned Tubes are required to accomplish the same heat transfer as bare tubes
  • Reduced retrofitting cost for existing equipment. 
    NEOTISS™ HPT Finned Tubes can increase the performance of an existing heat exchanger without the difficult and expensive task of building new shells, heads, nozzles, piping and foundations.
  • Space, weight & structural savings. 
    Reduced plot space and weight can be extremely valuable in offshore production or high elevation distillation columns. NEOTISS™ HPT Finned Tubes technology transforms large shell & tube exchangers into compact heat exchangers.
  • More materials & alloys to select .
    NEOTISS™ HPT Finned Tubes is available in a wider range of alloys than traditional low-fin tubing which is restricted to soft metals. This opens a new world of opportunity for enhanced tubing in corrosive service. The more expensive the tube material is, the more dramatic the cost savings of NEOTISS™ HPT Finned Tubes are.
  • Reduced maintenance & life cycle cost. 
    Proper material selection with Fine-Fin can eliminate costly downtime & maintenance.
    Example: Coastal refineries using once-through seawater cooling systems can benefit by substituting conventional copper nickel tubing NEOTISS™ HPT Finned Tubing which is immune to seawater corrosion erosion.

NEOTISS™ HPT Finned Tubes Types

Low Fin Smooth Bore
  • Provides external heat transfer area enhancement 2.5 to 3 times greater than smooth tube.
  • Offered in a wide range of fins-per-inch (FPI) densities, this product can be used with both liquids and gases, in both condensation and evaporation environments.
  • Ideal for shell side controlling heat transfer applications.
Low Fin with Internal Rib
  • A dual-enhanced tube with external fins on the outside and a helical rib pattern on the inside.
  • Ideal for maximizing performance with low heat transfer coefficient liquids or gases.
  • Offered in a variety of materials and sizes.
Smooth OD with Internal Rib
  • For tube side controlling applications where increased inner surface area and turbulation can improve performance in both single and two phases flow.
  • Offered in a variety of materials and sizes.
Wave Tube
  • A dual-enhanced tube with external fins on the outside and a helical rib pattern on the inside.
  • Ideal for coaxial (tube in tube) heat exchangers with a lower pressure drop and hifher flow rates compared to a twisted tube.
  • Only offered in titanium.
