摘要： It is an object of the present invention to provide a conduit structure for molten glass, whereby even if molten glass is flown for a long time through a double-pipe structure portion comprising an inner pipe and an outer pipe joined together, stress load is little. The present invention provides a double pipe structure comprising an inner pipe and an outer pipe, wherein a supporting rib is provided between the inner pipe and the outer pipe to bridge the inner pipe and the outer pipe; wherein the supporting rib has an inner straight portion joined with the outer face of the inner pipe so as to extend along the longitudinal direction of the inner pipe, an outer straight portion joined with the inner face of the outer pipe so as to extend along the longitudinal direction of the outer pipe, and a connecting wall portion extending from the inner straight portion to the outer straight portion to integrate them; and the supporting rib has a concave portion along each of one side edge of the connecting wall portion present between one side end portion of the inner straight portion and one side end portion of the outer straight portion, and the other side edge of the connecting wall portion present between the other side end portion of the inner straight portion and the other side end portion of the outer straight portion, and reaching both side end portions of the respective straight portions via rounded portions, and the supporting rib has projecting portions formed on respective ends of the inner straight portion and respective ends of the outer straight portion.

摘要： It is an object of the present invention to provide a vacuum degassing apparatus configured so as to be capable of carrying out more simply exchange operation for an extension pipe made of heat-resisting metal and immersed in molten glass.
The present invention includes a vacuum housing, a vacuum vessel, an introduction pipe and a discharge pipe which are assembled by a plurality of bricks, and an extension pipe connected to at least one of the introduction pipe and the discharge pipe and made of heat-resisting metal. The extension pipe is constituted by a base end portion, a body portion formed so as to be continuous to the base end portion, and a sealing flange extending from an outer peripheral side of the body portion at a position where one end of at least one of the introduction pipe and the discharge pipe is connected to a through hole formed in an outer wall of the vacuum housing. The extension pipe is detachably fixed to the outer wall through a fixing structure disposed on an outer peripheral portion of the sealing flange, at a position where the extension pipe has the base end portion placed into an end brick constituting an opening in one end of the introduction pipe or an opening in one end of the discharge pipe and where the sealing flange covers through holes formed in the outer wall.
