NEOTISS™ HPT Finned Tubes

NEOTISS™ HPT FINNED TUBES

History: In 1974 HPT (High Performance Tube, Inc.) pioneered the manufacture of integral low-fin tubing in hard to work alloys such as titanium, stainless steels, and high nickel alloys. This innovation paved the way for new industrial applications of enhanced surface heat transfer. In 2013 the HPT Fin Tube production was moved to Morristown TN USA and integrated into our titanium and stainless welded tube facility. NEOTISS continues to expand upon the HPT Fin Tube product line and remains an industry leader in enhanced surface tubular products.  

heat exchangers

Applications: NEOTISS HPT Low-Fin Tubes are used in shell and tube type heat exchangers to improve energy efficiency in refining, petrochemical, LNG, power generation, refrigeration, heating and air conditioning plants world-wide.

 

Benefits: Increased surface area for heat transfer, smaller heat exchanger, less number of heat exchangers, reduced equipment and installation cost, debottlenecking existing heat exchangers, upgrading to corrosion resistant alloys without sacrificing heat transfer efficiency, and reduced fouling (in some cases).
