Key Projects Application
Oil & Gas Industry
1.LNG (Liquefied Natural Gas) Plants: used in cold boxes, vaporizers, and heat exchangers (–196°C cryogenic applications).
2.Refineries & Petrochemicals: heat recovery from low-temperature streams (e.g., ethylene chillers).
Power Generation
1.Nuclear Power Plants: condensers and auxiliary cooling systems (corrosion-resistant in wet environments).
2.Geothermal Plants: heat exchangers for brine/working fluid heat transfer.
Cryogenic & Chemical Processing
1.Air Separation Units (ASU): heat exchangers for nitrogen/oxygen liquefaction.
2.Ammonia & Fertilizer Plants: ooling loops in urea synthesis.
HVAC & Industrial Cooling
1.District Cooling Systems: low-finned tubes enhance efficiency in chilled water exchangers.
