Title:
PIPE AND ROLLING STOCK
Document Type and Number:
WIPO Patent Application WO/2012/147517
Kind Code:
A1
Abstract:
Provided are: a novel pipe capable of minimizing an increase in internal temperature while minimizing thermal degradation of an opposing member even when a high-temperature fluid is circulated inside the pipe; and rolling stock having the pipe. The pipe is characterized in that a heat-dissipation unit and a heat-dissipation-minimizing unit are provided on the outer surface of a pipe-shaped substrate, and the emissivity of the heat-dissipation unit at a wavelength of 2 to 15 µm is higher than the emissivity of the heat-dissipation-minimizing unit at a wavelength of 2 to 15 µm. The rolling stock is characterized in having the pipe, the rolling stock preferably having the pipe as a pipe for discharging vehicle exhaust gas.
