Title:
HEAT EXCHANGER AND HEAT EXCHANGER CORROSION PREVENTION METHOD, AND HAND TOOL FOR WINDING TAPE USED FOR HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2017009235
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent low-temperature corrosion at low cost, be capable of installing in a low-temperature corrosion atmosphere to recover unused low-temperature heat energy and readily and easily prevent low-temperature corrosion for a heat transfer pipe.SOLUTION: A bare tube-type heat exchanger exchanges heat by indirectly bringing fluid flowing through the metal heat transfer pipe 4 into contact with an exhaust gas G flowing outside of the heat transfer pipe 4, where a surface of the heat transfer pipe 4 coming into contact with the exhaust gas G is covered by a corrosion-proof tape 9.SELECTED DRAWING: Figure 1
