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.
Applications
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.
Benefits
- 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.
