Apparatus for glass manufacturing

A glass manufacturing apparatus comprising:

• a conduit comprising an interior passage defining a conduit cross-sectional footprint with a first cross-sectional area at a first position along a length of the conduit, the interior passage configured to carry a flow of molten glass therethrough;
• at least one expansion drum positioned at a second position along the length, the at least one expansion drum defining an expansion drum cross-sectional footprint with a second cross-sectional area at the second position greater than the first cross-sectional area, the expansion drum cross-sectional footprint extending outside of the conduit cross-sectional footprint;
• a casting disposed about the conduit;
• and
• at least one reinforcing member attached to and extending along a portion of the length of the conduit, the at least one reinforcing member engaged in the casting.

A glass manufacturing apparatus, comprising:

• a first conduit extending between a first expansion drum and a second expansion drum, the first conduit comprising an interior passage configured to carry a flow of molten glass therethrough, the first conduit defining a first cross-sectional area at a first position along a length of the first conduit, the first expansion drum defining a second cross-sectional area greater than the first cross-sectional area at a second position along a length of the first expansion drum, and the second expansion drum defining a third cross-sectional area greater than the first cross-sectional area at a third position along a length of the second expansion drum;
• a first electrical flange connected about the first expansion drum;
• and
• a second electrical flange connected about the second expansion drum.
