Description

I

The invention relates to welding, in particular to methods for attaching a package of pipes to a plane, and can be applied when installing shielded conduits in concealed wiring and other mechanical engineering industries where it is necessary to attach a package of pipes to planes.

The aim of the invention is to increase the quality of constructions and reduce the labor intensity of installation.

Fig. 1 shows a tank in the form of a pull box (without a lid) used to connect individual sections of shielded process piping that are part of a conduit; Figures 2 and 3 are views of the walls of the draw box with panels of inserts of some possible shapes; Fig. 4 is a section A-A in Fig. 2 (along the wall of the draw box through the inserts); on .fig.5 - intermediate inserts of some possible forms a, 6.

The method of attaching a package of pipes to a plane in the form of a wall is as follows.

On individual metal plates with a thickness of about 1.5 mm they are formed with a tampon or another method Patrubi 1 of a small height of 10-15 mm. The sleeve 1 can have a cylindrical or conical shape a, S, 6. At the end of the nozzle, an opening 2 should be formed corresponding to the diameter of the pipe that is attached to this nozzle. Around the base 3 of the nozzle 1, a flange 4 forms a part of the original plate, which symmetrically with the base 3, the nozzle 1 is shaped like a square, with a side 10-50 mm larger than the diameter of the base

3 pipe 1. The flange 4 and the pipe 1 form an intermediate insert 5 of factory production. The nomenclature of the inserts 5 depends on the diameter of the pipes used. In order to create conduits in concealed wiring, 4-5 sizes of inserts 5 are sufficient. When installing a conduit for a specific package of pipes, the panel 6 is assembled from the required number and sizes of inserts 5 by welding the sides of the flanges

4 stitches 7 to the joint without gaps. In this case, the nozzles 1 of the inserts 5 to 4 "dreams should be directed in one direction to the flanges 4 before welding to be given any necessary shape, a simple edge

 Coy (figs, 5,6). Depending on the sizes of the inserts 5, their number and the shape of their flanges 4 receive different types of panels (FIGS. 2 and 3).

Then, in the bottom or wall of the cabinet or Jalcik 8, a hole 9 common to the entire package of pipes is cut out so that it is free of fittings 1 welded inserts and so that the hole is overlapped with the flat part of the panel 6 formed from the welded flanges of the inserts. B from: - overlap with a seam; 10 weld the panel with 6 branch pipes inside the cabinet or crate 8.

The tubes of the bag are inserted into the pipes 1 on the outside of the crate. The ends of the pipes are combined with the ends of the nozzles, tolerance offset the end of the pipe and the pipe relative to each other by 2-3 mm, and weld each tube to the corresponding pipe with a solid seam around the perimeter of the pipe end from the inside of the cabinet or drawer 8.

Compared to a dense tube bundle, the distance between the tubes increases slightly, since the flanges of the inserts at several points, for example, along the axis of the row of inserts in the panel, can be completely cut off in such a way that only the pipe wall thickness is welded. at these points butt seam 7 (figure 4).

It is possible to replace the welding between the pipe, and the end of the nozzle for soldering. In this case, a gasket made of a low-melting metal is placed between the pipes and the end of the pipe. When soldering, the Q-ladder melts, the molten metal fills the gaps, solidifies, fixes the pipe in the pipe and creates an electromagnetic tightness.

The advantages of the proposed method are that it makes it possible to unify the preparation of places for welding a package of pipes to the walls. cabinets and cabinets, while maintaining

the minimum areas of these walls required for welding a package of pipes.

In addition, for the drawers that are fully assembled during the installation of cable ducts, the method makes it possible to assemble a whole welded wall with patches and weld it to the rest of the drawer or cabinet.

With a small range of panels it is possible to assemble them in factory conditions 30

METHOD FOR ATTACHING PIPE PACKAGE TO PLANE, including making holes for pipes in intermediate inserts in the form of plates, placing pipes in these holes, welding pipes to plates with an annular seam, welding plates between themselves and with a plane, characterized in that, in order to improve the quality of construction and reduce the complexity of installation, in the plates they form nozzles with holes, assemble and weld the plates in the panel, having the nozzles on one side of the panel, in the tube board an opening with a configuration corresponding to panel configurations, and with a size smaller than the size of the panel, install the panel in an overlap hole and weld to the tube plate, then install the pipes into the nozzle holes, jg placing the pipe end flush with the pipe end, and weld to it.
