Definitions
- This invention relates to a method for the subsequent production and revision of a stub line with a flow and return channel according to the preamble of claim 1.
- the patent DE 36 34 106 shows the formation of a stub with a flow and return channel.
- the inner pipe had to protrude beyond the steel pipe connection of the branch in order to be able to make the connection technically.
- connection could only take place step by step between the stub and the inner pipe, in such a way that the connection for the inner pipe had to be established first and then the stub could be welded.
- the protective sleeve had to be pulled out of the space between the return channel using a previously threaded pull rope in order to protect the inner tube from the heat generated during welding. Subsequent replacement of an inner tube or a revision was no longer technically possible or very difficult. This initial situation also hindered the use of a cheaper plastic for the inner tube.
- the invention is therefore based on the object of subsequently producing, assembling and revising the inner tube (10) or the branch line from the house connection side at the heat consumer without the inner tube being caused by the heat generated when welding the branch line (1) (as Plastic jacket composite pipe drawn) is at risk. Furthermore, the workflow in the production of the branch line (1) no longer disabled, but extremely simplified. The inner tube can thus be manufactured and assembled in a few minutes.
- Fig. 1 shows the connection of the branch line to the single-pipe district heating duct as a branch.
- Fig. 2 shows the house connection.
- the manufacture, assembly and later revision of the inner pipe (10) or the branch line is done directly from the house connection side of the heat consumer over a greater distance from here to the branch.
- One end of the inner tube (10) is connected to a special transition sleeve (15) by means of socket welding and inserted into the branch line through the opened flange ring (7).
- Parts of the inner tube are joined together, for example by welding, to form longer tube units and are gradually pushed into the branch line.
- the inner pipe can e.g. unrolled from a reel or spool and processed into a complete inner tube unit - without sections. Additional weld connections on the inner tube can then be avoided.
- the inner pipe with the special transition sleeve (15) is forcibly centered by means of a wedge ring (14) or wedge segments, which are offset by three times 120, and guided to the threaded pipe nipple until a significant thrust resistance occurs.
- the protruding inner pipe is now clamped by hand or a suitably prepared tool, a prism-shaped tap wrench, and screwed onto the threaded pipe nipple (16).
- the threaded pipe nipple is welded directly behind the elbow (18) of the branch. This also eliminates the need for a larger steel tube adapter as an unnecessary heat exchanger surface.
- the wedge ring (14) or the wedge segments are arranged so that the special transition sleeve that the special transition sleeve (15) with the inner tube safely centered and the flow in the return channel is not unnecessarily obstructed.
- the outer diameter of the special transition sleeve to the return channel must also be adjusted.
- the wedge ring (14) or the wedge segments can be fastened, for example, by brazing or welding. Due to the positive centering, it is possible that the inner pipe can also be securely screwed together from a distant house connection side to the branch.
- the length of the branch line can be more than 35m! After dimensioning the temperature-dependent longitudinal expansion space, the interior Shorten tube 2u.
- the loose flange end (8) is provided with a flat seal (12) and pushed with O-rings (4) over the inner tube and tightened and sealed with the flange screws. Two O-rings are provided for safety reasons.
- the tube (2) is welded to the flange ring (7).
- the guide tube (11) is welded to the flange (8) and uses the O-rings to guide and mount the inner tube.
- the threaded pipe piece (3) is welded to the pipe (2).
- Two reducers (20) are welded to the pipe section (19).
- the elbow (18) is to be welded as far as possible off-center in the cross-sectionally enlarged pipe section (19).
- the deflecting part (17) is arranged at an angle of approx. 30 - 35 and offers the lowest flow resistance.
- Three flat irons welded offset by 120 serve as a fixed point (13).
- the wedge ring (14) or the wedge segments are not clogged by deposits or damaged by corrosion. This can be influenced favorably by the shape and choice of material.
