Set of pipes and pipe connection elements.

When welding pipes and pipe connection elements together it is often difficult to bring these pipes and elements exactly into the required, correct position. The invention aims to provide a remedy here. It concerns a set of pipes and pipe fittings. The same is characterized according to the invention in that each pipe and each connection element on its outer Surface is provided with a plurality of orientation lines to facilitate the welding of these pipes or To facilitate closing elements in correct mutual position.

An exemplary embodiment of the subject matter of the invention is shown in the drawing. It is:

Figure 1 is a schematic view of a set of interconnected

Pipes and pipe connection elements;

and
Fig. 2 is a cross section through a pipe,

according to line II-II of Fig. 1. According to FIG. 1, a connection element (“Y-piece”) 2 with an inclined branch connection 3 is welded to a pipe 1. A pipe 4 is welded to the latter, while a pipe 5 is welded to the end of the connecting element 2 opposite the pipe 1. A T-connection element follows the pipe 5 in the same way 6, which is connected to a reduction connection elbow 7 and to a tube * · 8.

Around the pipes 1, 4, 5 and 8 and the connecting elements 2, 6 and 7 in the position shown with one another to butt weld, i.e. so that the axes of the pipes 4 and 8 and the arcuate axis of the element 7 in one plane, namely in the plane of the drawing, are used So far, all sorts of auxiliary devices, in particular stops, which are adapted to the dimensions of elements 2, 6 and 7 are. These auxiliary devices have to be prepared on a case-by-case basis and are also a quick sweat. work rather cumbersome. To get the necessary alignment of the

To make pipes and connection elements easily recognizable and thus the annoying auxiliary devices mentioned The pipes and connection elements are provided with orientation lines 9 on their outer surface.

In the present case, each pipe is with

four continuous orientation lines are provided which run parallel to its axis, with adjacent lines being offset from one another by a central angle of 90, as is shown in FIG. 2 for the tube 1. In the case of the connection element 2, which is formed from two hollow cylindrical parts inclined towards one another, four orientation lines 9 are provided with respect to each of the two axes of the hollow cylindrical parts. The same applies to the T connection element 6. In the case of the reduction bend 7, two orientation lines 9 ... and 9 ~ are defined as intersection lines of the plane (drawing plane) in which the curved axis lies and the outer surface of the bend 7, and the orientation lines 9 "Or 9. (The latter not visible), as intersection lines of a general cylinder surface, which is perpendicular to the axis plane and generated by the axis, with this outer surface. Also in this case are

lines 9-9 in each cross-section of the arch. offset by 90 from each other.

If a set of pipes and connection elements marked as described is available, they can be welded to one another in the correct position without any effort, simply by setting the welding temperature heated ends of the ears and elements in such a Position must press against each other that the desired composition corresponding ends of orientation lines fall on each other.

It is clear the same result as well

can be achieved if the orientation lines 9 do not continuously, but only at the ends of the tubes or elements are marked. It can also be seen that you can also provide more or less than four orientation lines. If line branches under special At angles, e.g. 30 or 45 overturning, you will expediently have more than four, e.g. six or eight orientation lines provide. In general, however, four guidelines will suffice.

Claims (4)

_ _ RA.269016 * 5/25/65 protection claims 1. Set of pipes and pipe connection elements, characterized in that each pipe and each connection element is provided on its outer surface with a plurality of orientation lines (9) to allow the welding together to facilitate these pipes or connecting elements in the correct mutual position. 2.
