Abstract: A device which suspends a horizontal heat-exchanger tube from a vertical supporting tube, including a flat section member adapted to be welded to an outside wall of the vertical supporting tube and parallel to an axis thereof, the flat section member being provided with a rounded notch which receives a support piece adapted to accommodate the horizontal tube, wherein the tube-receiving support piece is a folded metal sheet that is folded to match a shape of the notch and adapted to surround a portion of an outside periphery of the tube, the support piece having a top end and a bottom end, each of the ends being folded over towards the flat section member so as to be welded thereto, and wherein a collar adapted to enclose the horizontal tube is fixed against the tube-receiving support piece.

Abstract: A device for suspending a horizontal heat exchange tube on a vertical support tube is provided comprising:(a) an element for securing the horizontal tube, in the general form of a cradle, consisting of two symmetrical cylindrical cross-bars and two connecting members for the cross-bars in an arc of a circle;(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 and an oblique portion forming a folded-over part; these elements 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.

Abstract: A device for suspending horizontal heat exchange tubes (7, 8) on a vertical carrier tube (1) comprises a bottom support sleeve (2) welded at its bottom edge around the support tube, a top support sleeve (4) having its bottom edge resting on the top edge of the bottom support sleeve, said top support sleeve being provided on its sides with two half-shells (5, 6) of radius of curvature slightly greater than that of the horizontal tubes, and add-on half-shells (9, 10) of radius of curvature slightly greater than that of the horizontal tubes, welded edge-to-edge (19, 21; 20, 22) to the half-shells fixed to the top sleeve, thereby forming collars which clamp the horizontal heat exchange tubes on either side of the vertical carrier tubes. A method of manufacturing the device.
