Abstract:
A conduit structure for molten glass, in which molten glass is flown through a double-pipe structure, with little stress loading even for a long time operation. A supporting rib connecting an inner pipe and an outer pipe is employed in the double pipe structure having the inner pipe and outer pipe in the conduit structure for molten glass, wherein excessive stress concentration hardly occurs in an inner pipe-joint portion, an outer pipe-joint portion and the rib when the rib is applied with a stress load due to the weight of the inner pipe.
