Device for suspending a horizontal heat exchange tube on a vertical support tube

Device for suspending a horizontal heat exchange tube on a vertical support tube, wherein it comprises:

• (a) an element for securing the horizontal tube, in the general form of a cradle, comprising:
• (i) two symmetrical cylindrical cross-bars having an inner surface of radius of curvature slightly greater than that of the horizontal tube, and generating lines parallel to the axis of this tube, separated by an empty space, these cross-bars having on the side opposite said empty space an acute-angled wedge-shaped part;
• and
• (ii) two connecting members for the cross-bars in an arc of a circle, each including a circular edge having a radius of curvature equal to that of the horizontal tube, in a plane perpendicular to the axis thereof, and tapering outwards on their outer side with respect to the empty spare;
• said securing element being welded to the horizontal tube along the circular edges of the members;
• (b) two elements for securing the vertical tube, each comprising a plane portion provided on their side facing the vertical tube with two lateral edges parallel to the axis of this tube, and an oblique portion forming a folded-over part defining with the surface of the plane part opposite the vertical tube an acute-angled recess corresponding to that of the wedge-shaped part of the cross-bars, these elements, of width smaller than that of the cross-bars of the elements securing the horizontal tube, interlocking by engagement of their recesses with the wedge-shaped parts of the cross-bars of the securing element for the horizontal tube, and being welded to the vertical tube along the lateral edges of their plane portion.
