Description

[0001] FIG. 1 is a perspective view of a heat-resistant tube for vertical heat treatment equipment showing our new design;

[0002] FIG. 2 is a front view thereof;

[0003] FIG. 3 is a top view thereof;

[0004] FIG. 4 is a bottom view thereof; and,

[0005] FIG. 5 is a cross-sectional view taken along the line 5-5 in FIG. 3.

[0006] The rear view, the right side view, and the left side view of the heat-resistant tube for vertical heat treatment equipment are the same as the front view and thus are omitted. The cross-sectional view of FIG. 5 shows the cross-hatched internal regions, which do not form part of the claimed design.

Claims
