Austenitic Steel Sanitary water heat exchanger stainless steel coil tube for High pressure
High pressure stainless steel coil heat exchanger is used to raise the temperature of the fluid to prevent hydrate formation, reduce viscosity, and break down emulsions for efficient separation of oil ,gas and water, providing heat directly from adequate steam usually supplied by a steam generator.The heat exchanging efficiency of this kind of method is higher and can eliminate potential fire risk.
