ジ継手。 An inlet-side flange and an outlet-side flange that are electrically insulated and connected via an electrically insulating seal member, a ceramic insulating pipe provided within these flanges across both flanges, and a ceramic insulating pipe that is longer than this insulating pipe. A metal heat-insulating pipe sleeve formed to surround the heat-insulating pipe, a cooling water pipe disposed within the gap between the outer periphery of the heat-insulating pipe sleeve and both flanges, and at least one of the cooling water pipe, the heat-insulating pipe, and the heat-insulating pipe. an insulating member that electrically insulates the flange of the insulating pipe, and a metal arranged in series with the insulating pipe to compensate for the lack of axial length of the insulating pipe by taking into account the difference in thermal expansion between the insulating pipe and the insulating pipe sleeve. An electrically insulating flange joint comprising: a short pipe; and a holding nut that is tightened and fixed to the end of the heat-insulating pipe sleeve to prevent movement of the heat-insulating pipe in the axial direction via the short metal pipe.
