Abstract

A branch connection (11) on a tubular component comprises a number of concentric pipe unions (12, 14, 16, 18) one inside the other. These extend alternately to the outside and inside of the components, and are joined together by annular bodies (15, 17, 18). The outermost union is joined to the component.

Description

450 161 standardrördimensioner. Stutsarna 12 och 16 konar av inåt, medan stutsarna 14 och 1É ör huvudsak1igen cy1indriska. 450 161 standard pipe dimensions. The stubs 12 and 16 are inward, while the stubs 14 and 1 are substantially cylindrical.

Grenans1utningarna utgör en integrerad de1 av brunnsröret 10 och är framstä11da ti11samman med detta genom rotations- gjutning, exempe1vis i polyeten PEM.The branch orifices form an integral part of the well pipe 10 and are made together with it by rotational molding, for example in polyethylene PEM.

I det i FIG. 1 visade ti11ståndet är grenans1utningen he1t ti11s1uten och avsedd att inte användas för ti11kopp- 1ing av något rör. ' Om den innersta stutsen 12 kapas efter 1injen I i FIG. 1 för av1ägsnande av membranet 13, kan ett rör kopp1as ti11 brunnen vid denna stuts, varvid röret stickes in i den in- vändigt konande stutsen.In that in FIG. In the condition shown in Fig. 1, the branch outlet is completely closed and is intended not to be used for connecting any pipe. If the innermost socket 12 is cut after the line I in FIG. 1 for removing the diaphragm 13, a pipe can be connected to the well at this nozzle, the pipe being inserted into the internally tapered nozzle.

Om kapning av stutsarna 12 och 14 sker efter 1injen II i FIG. 1, erhå11er grenans1utningen utseendet en1igt FIG. 2 Qch kan ett rör med större dimension kopp1as ti11 stutsen 14, genom att det införes i denna stuts. Det finns eme11er- tid också möj1ighet att kopp1a ett något större rör ti11 stutsen 14, genom att detta rör skjutes utanpå stutsen.If the stubs 12 and 14 are cut after the line II in FIG. 1, the branch appearance has the appearance according to FIG. A larger dimension pipe can be connected to the socket 14 by being inserted into this socket. However, it is also possible to connect a slightly larger pipe to the socket 14, by this pipe being pushed onto the outside of the socket.

Om kapning av stutsarna 12, 14 och 16 sker efter 1injen III i FIG. 1, erhå11er grenans1utningen utseendet en1igt FIG. 3, och nu kan ett rör med ännu större diameter kopp1as ti11 stutsen 16 genom att det införes i denna stuts.If cutting of the nozzles 12, 14 and 16 takes place after the line III in FIG. 1, the branch appearance has the appearance according to FIG. 3, and now an even larger diameter pipe can be connected to the socket 16 by inserting it into this socket.

S1ut1igen kan ett största rör kopp1as ti11 grenans1ut- ningen, om kapning sker efter 1injen IV i FIG. 1, varvid samt1iga stutsar kapas och grenans1utningen erhå11er utseen- det en1igt FIG. 4. Ti11kopp1ingen av röret sker då vid stutsen 18, som i vissa fa11 kan av1ägsnas he1t vid kapningen.In addition, a larger pipe can be connected to the branch outlet, if cutting takes place after line IV in FIG. 1, in which all the sockets are cut and the branch opening acquires the appearance according to FIG. 4. The connection of the pipe then takes place at the socket 18, which in some cases can be removed completely during the cutting.

Kapningen av stutsarna sker sâ1unda antingen utanpå e11er inuti brunnsröret 10, beroende på vi1ken dimension som ska11 användas, och den kan utföras med fintandad såg e11er skarp kniv. f..The cutting of the nozzles thus takes place either on the outside or inside the well pipe 10, depending on which dimension is to be used, and it can be carried out with a fine-toothed saw or a sharp knife. f ..

Claims

Claim device Branch outlet (11) on a tubular element (10), characterized in that the branch outlet (11) comprises a number of concentrically arranged pipe spouts (12, 14, 16, 18), which project alternately. on the outside and inside of the tubular element and there are interconnected medial annular livers (15, 17, 19), which are made in one piece with the adjacent pipe sockets, of which the outermost pipe socket (18) is made in one piece with the tubular element (10), the pipe fittings being gradually retracted on both the outside and the inside from the innermost to the outermost pipe socket.
