Title: Method of joining heating pipes
IPC: F16L59/20
Filed: 1989-08-25
Granted: 1992-05-27
Abstract: For the joining of heating pipes (1; 2), which are composed of a medium pipe (3) made of steel, a jacket pipe (4) made of plastic and foam filler (5) in between, the medium pipes (3), which are exposed at the ends, are welded (6) in a known manner. A bridge (8) is then placed over the gap between the foam fillers (5) and supported on the two previously exposed ends (7) of the foam fillers. The bridge (8) is composed of a sideways U-shaped profile made of aluminium sheet; its arms are pressed into the foam. The gap between the jacket pipes (4) is then closed by flush insertion of a jacket pipe transition piece, the transition piece being connected to the two adjacent jacket pipes (4) by seams, in particular welded seams, and being closed at a longitudinal section. In this case, the bridge (8) serves as a support on said longitudinal section so that the transition piece does not shrink and sink in due to the heating on the longitudinal seam. Subsequently, the cavity is filled with foam. <IMAGE>

Abstract: In order to fill the interior of an insulating glass pane (1) with argon, during pressing of the insulating glass pane (1) one glass pane is held in the region of a corner (2) at a distance from the spacer frame by holding this glass pane at a distance from the spacer frame by swivelling a part (12) of the press plate (11) using suction heads (19, 20) provided on this part (12). Inserted through the gap thus formed are a probe (4) for supplying argon and a probe (5) for extracting air from the interior of the insulating glass pane. The probe (4) through which argon is blown into the interior is aligned parallel to the lower horizontal limb of the insulating glass pane (1), and the other probe (5), via which air or air/argon mixture is extracted, has an opening which points obliquely upwards, i.e. away from the other probe (4). As a result, it is possible to produce insulating glass panes (1) having a filling of the interior other than air without it being necessary to bore holes in the spacer frame, the gas exchange taking place such that argon is mixed with the air displaced from the interior only to a very limited extent.
