ABOUT DOUBLE WALLED TUBE HEAT EXCHANGERS:
Double walled tube has a purge passage coiled through the middle of the tube wall. The bi-walled tube should be used when the heat exchanger is part of critical equipment design or is primarily safety related.
APPLICATIONS:
- When the exchanger is in contact with hazardous material i.e., cooling Tritium gas at a nuclear facility.
- When the process and cooling sides react violently i.e., water and sodium.
- When an exchanger failure would incur expensive downtime i.e., feed water exchange at a utility power plant.
- When an exchanger failure would seriously damage expensive equipment i.e., an oil cooler on a gas turbine.
