NEOTISS™ HPT Finned Tubes

NEOTISS™ HPT Finned Tubes are a finned tubular solution that yields numerous benefits for shell-and-tube heat exchangers. 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, paving the way for new industrial applications of enhanced-surface heat transfer.

Applications

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

Benefits

• Increased surface area for heat transfer
• Smaller heat exchanger footprint
• Fewer heat exchangers required
• Reduced equipment and installation cost
• Debottlenecking existing heat exchangers
• Upgrade to corrosion-resistant alloys without sacrificing heat transfer efficiency
• Reduced fouling (in some cases)
