Definitions
- the invention relates to the production of a connection between a pipe and a block with a pipe.
- Pipes are used to transport media. This can be any fluid, such as gas or oil, that needs to be supplied to a block in general, for example an engine block, a bearing block or a combustion part, etc.
- the pipe can be connected to the block by a screw connection, a metallurgical connection (i.e. soldering or welding), although the latter cannot be easily replaced when the pipe is renewed.
- a screw connection i.e. soldering or welding
- the object is achieved by a method according to claim 1 and an arrangement according to claim 6.
- Figure 1 a block with pipe in the initial state
- Figure 2 3 process steps
- Figure 4 a revised block with new pipe.
- Figure 1 shows a device 1 consisting of a block 4 and a pipe 7 connected to the block 4.
- the block 4 is preferably part of an oil supply or distribution system .
- the block 4 can preferably have further supply lines or discharge lines.
- the block 4 is metallic and preferably comprises a steel. This is preferably an austenite.
- the tube 7 is also metallic and preferably comprises a steel. This is preferably an austenite.
- the tube 7 comprises the same material as the block 4.
- Pipe 7 and block 4 were preferably connected to one another by a soldered connection 10 or other metallurgical connection at least within the block 4 or with the block 4.
- soldering process in a furnace with block 4 and tube 7 together, for example with several blocks/tubes together. Not only the soldering process as such is carried out, but if necessary also a soldering heat post-treatment of a metal.
- a soldered connection always means a heat treatment of the entire arrangement to create the soldered connection, which can be done locally in a furnace or only with a block, but only with greater effort.
- the pipe 7 is to be replaced. A simple detachment is not possible with a soldered or welded connection. The pipe 7 is therefore severed, but a part of the pipe 7 is deliberately retained above the block 4 as a stump 13 ( Figure 2).
- a support structure 16 is therefore created around and/or on the stump 13 (Fig. 3).
- the support structure 16 can be produced by known additive forming processes such as LMD or WAAM, i.e. a welding application of material, in the form of powder or by means of a of a wire.
- the new pipe 77 preferably comprises the same material as the pipe 7 or preferably as the block 4.
- the support structure 16 is or will be created in such a way that the new pipe 77 can or will be introduced therein.
- the new pipe 77 is then or is welded there to the support structure 16 and/or stump 13.
- the welding of the new pipe 77 to the support structure 16 and/or stump 13, possibly also block 4 can be carried out by pure remelting or also with welding filler material.
- the same material is preferably used as the welding filler material as for producing the support structure 16.
- a solder joint always involves a heat treatment to create the solder joint, which can be done locally on site in a system in an unavailable furnace or even just with a block, but only in a more complex way. Then this production can be used.
- new metallurgical welded joint between new pipe 77 and support structure 16 and/or block 4/stump 13 does not require heat treatment. This can preferably be achieved by a targeted selection of materials.
- a steel with manganese (Mn), silicon (Si), chromium (Cr) and nickel (Ni) is preferably used.
- the material of block 4 should also preferably a steel with a steel with chromium (Cr), nickel (Ni), if possible but preferably without manganese (Mn), but with silicon (Si).
- Cr chromium
- Ni nickel
- Mn manganese
- Si silicon
- P phosphorus
- N 2 nitrogen
- S sulphur
