Title: HEAT-INSULATED PIPE ARRANGEMENT
Abstract:
This heat-insulated pipe arrangement (1) is provided with a pipe (2) through which a fluid can be distributed and a heat-insulating member (3) which is disposed so as to surround the pipe (2). The pipe (2) is used for an exhaust gas purification device utilizing an SCR catalyst, and the heat-insulating member (3) has a closed-cell structure and can suppress an increase in the temperature of the fluid due to heat-exchange with the atmosphere. Because of this configuration, the inside of the pipe (2) of an exhaust gas purification device utilizing an SCR catalyst is thermally insulated from the outside by the heat-insulating member (3), and an increase in the temperature of fluid distributed through the pipe (2) due to heat-exchange with the atmosphere can be suppressed.
