COOLING JIG OF HIGH TEMPERATURE PIPELINE, COOLING DEVICE, AND INSTALLATION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To reduce temperature of high temperature pipeline without reducing operation temperature of a plant, and thereby reduce a creep fracture risk by operating a temperature condition.SOLUTION: A cooling jig of a high temperature pipeline includes: a plate-like heat absorption part 31 mounted along an outer peripheral surface 11 of a principal part of a high temperature pipeline 1; a heat absorption surface 32 formed on one surface of the heat absorption part 31 and configured to absorb heat from the outer peripheral surface 11; and a plurality of heat radiation plate parts 33 projecting from another surface of the heat absorption part 31. On the heat absorption surface 32 side of the heat absorption part 31, a notch 41 for bending the heat absorption part 31 into a curved shape along the outer peripheral surface 11 is protrusively provided in parallel with an axial direction of the high temperature pipeline 1.SELECTED DRAWING: Figure 1
