Description

Utility model registration LV - / << suspension of pipes " The innovation relates to the suspension of pipes in heated rooms, in particular on the suspension of horizontally arranged superheater tubes in boiler trains.

The superheater tubes are arranged in vertical boiler passes are, mostly as pipe coils, the pipes of which are essentially horizontal, formed and suspended from vertical water-cooled or steam-cooled pipes. the The suspension should be designed in such a way that the pipes freely follow thermal expansions can, but still not detach from their attachment. One uses since then for this purpose support fins, parallel jaws and cross jaws. All known fortifications have the disadvantage that they quickly scale and scale when exposed to high heat therefore must be made from relatively expensive materials.

According to the innovation, a downward widening, for example, conical pin welded in, at its upper end in a Ball head passes. One also grips the pipe to be suspended over the ball head claw open at the bottom, attached and welded on a broad base, its insertion slot includes the ball head and prevents falling out.

The innovation ensures that the heat is dissipated well on the one hand the retaining pin on the hanger tube, on the other hand from the claw piece to the Achieved supporting superheater tube, which makes it possible to replace the expensive Sicro materials to switch to the material TS 57, which has the further advantage of being oil-fired Boilers to be less sensitive to external influences.

The recess intended for the ball head is expediently widened in the claw piece on both sides. This ensures that the Longitudinal expansion of the pipes to be suspended To be taken into account can. Of course, the outer shape of the claw piece can be fluid-related and pollution-related aspects.

With the exception of minor machining, the parts can be finished in the die , whereby the production is cheaper.

In the figures, an embodiment of the invention is in two Shown sections, namely Fig. 1 shows a vertical section, with the support tube and retaining pin are drawn in full and Fig. 2 shows a horizontal section with full lined worn pipe.

The support tube is denoted by 1 in both figures, which is 2 suspended pipe. A retaining pin 3 with a ball head is welded to the support tube 1 4. The retaining pin is tapered so that it is relatively wider Surface on the tube 1 rests. A claw piece 5 is welded to the tube 2. The claw piece also rests against the pipe with a wide base and secures thus good heat dissipation. The claw piece has a recess 15, which according to the neck of the retaining pin becomes narrower and is open at the bottom. The claw piece can therefore be pushed from above over the ball head, but is against slipping out secured in a lateral direction (to the right). After another thought the The innovation is that the recess for the ball head is widened to the side, like it is particularly shown in Fig. 2 by the dashed line 6.

Claims (1)

Sqhe AD d on l.) Shinging of pipes, characterized by one in the Fastened support tube, made of spherical head and then tapered Shank existing retaining pin and one on the pipe to be carried attached claw, which with a, the shape of the ball head fitted, downwardly open recess is provided. j4M t / 2.) hS'aufhangung v'orr pipes according to claim l, characterized in that u net that both the retaining pin and the claw piece with wide area on the pipe connected to them. ? 3.) suspension vo pipes according to claims 1 and 2, thereby characterized that the receiving opening for the ball head sideways lich is widened.
