Description
ANORDNING VED RØRKOPLING FOR STIGE- OG SLUSERØR DEVICE FOR PIPE CONNECTION FOR RISE AND Sluice PIPES
Denne oppfinnelse vedrører en rørkopling for stige- og sluserør. Nærmere bestemt dreier det seg om en rørkopling for stige- eller sluserør som anvendes under kabel-eller kveilrørsarbeider i petroleumsbrønner, og hvor en første koplingsdel i aktiv posisjon holdes tettende koplet til en andre koplingsdel ved hjelp av en mutter. This invention relates to a pipe connection for riser and sluice pipes. More specifically, it concerns a pipe coupling for riser or sluice pipes used during cable or coiled pipe work in petroleum wells, and where a first coupling part in the active position is kept tightly connected to a second coupling part by means of a nut.
Såkalte hurtigkoplingsunioner (engelsk Quick Union) er velkjente i forbindelse med utstyr, så som stige- og sluserør (engelsk Lubricator Riser), for kabel- eller kveilrørs-operasjoner (engelsk Wireline eller Coiled tubing). Grunnet deres relativt enkle sam-menføyningsmåte hvor koplingsdelene føres sammen og mutteren trekkes til, er hurtigkoplingsunioner godt egnet til sammenføyning av komponenter som gjentatte ganger koples sammen og demonteres. So-called quick coupling unions (English Quick Union) are well known in connection with equipment, such as risers and sluice pipes (English Lubricator Riser), for cable or coiled pipe operations (English Wireline or Coiled tubing). Due to their relatively simple joining method where the connecting parts are brought together and the nut is tightened, quick coupling unions are well suited for joining components that are repeatedly connected and disassembled.
Kjente hurtigkoplingsunioner er utformet med gjenger mellom mutteren og den korresponderende koplingsdel, noe som medfører at mutteren må dreies et antall om-dreininger under sammenkopling og demontering. Dette gjøres vanligvis manuelt. Det kan være tungt å dreie mutteren fordi gjengene kan være skadet eller forurenset. Det har vist seg at operatører som arbeider med hurtigkoplingsunioner kan utvikle mus-kel-skjelettlidelser, for eksempel senebetennelser. Known quick coupling unions are designed with threads between the nut and the corresponding coupling part, which means that the nut must be turned a number of revolutions during coupling and disassembly. This is usually done manually. It may be difficult to turn the nut because the threads may be damaged or contaminated. It has been shown that operators working with quick coupling unions can develop musculoskeletal disorders, such as tendinitis.
Oppfinnelsen har til formål å avhjelpe eller å redusere i det minste én av ulempene ved kjent teknikk, eller i det minste å skaffe til veie et nyttig alternativ til kjent teknikk. The purpose of the invention is to remedy or to reduce at least one of the disadvantages of known technology, or at least to provide a useful alternative to known technology.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. The purpose is achieved according to the invention by the features indicated in the description below and in the subsequent patent claims.
Det er tilveiebrakt en rørkopling for stige- eller sluserør for anvendelse under kabel-eller kveilrørsarbeider i petroleumsbrønner, og hvor en første koplingsdel i aktiv posisjon holdes tettende koplet til en andre koplingsdel ved hjelp av en mutter. Rørkop-lingen kjennetegnes ved at mutteren innvendig er utformet med et antall om rørkop- lingens senterakse fordelte låseknaster som i mutterens låsende bruksstilling er i inngrep med korresponderende vulster på den andre koplingsdelen, og hvor låseknastene i mutterens i utløste bruksstilling er forskyvbare mellom nærliggende vulster. A pipe coupling is provided for riser or sluice pipes for use during cable or coiled pipe work in petroleum wells, and where a first coupling part in the active position is kept tightly connected to a second coupling part by means of a nut. The pipe coupling is characterized by the fact that the inside of the nut is designed with a number of locking lugs distributed around the central axis of the pipe coupling which, in the nut's locking position of use, engage with corresponding beads on the other coupling part, and where the locking lugs in the nut's released position of use are displaceable between nearby beads.
Mutteren er således innrettet til å føres inn over den andre koplingsdelen og dreies for eksempel 45 grader til sin låsende bruksstilling når mutteren er forsynt med fire låseknaster. Antallet låseknaster kan tilpasses forholdene, men det fordres uansett bare en begrenset dreiing av mutteren, sammenlignet med gjengede muttere, mellom mutterens låsende bruksstilling og mutterens utløste bruksstilling. The nut is thus designed to be inserted over the second coupling part and is turned, for example, by 45 degrees to its locking position when the nut is provided with four locking lugs. The number of locking lugs can be adapted to the conditions, but in any case only a limited turning of the nut is required, compared to threaded nuts, between the nut's locking use position and the nut's released use position.
Minst én av vulstene kan være forsynt med en stopper. Stopperen forhindrer at mutteren dreies for mye under tilkopling. Minst én av låseknastene kan være forsynt med en stopper. Stopperen forhindrer at mutteren dreies for mye under tilkopling. At least one of the beads may be provided with a stopper. The stopper prevents the nut from being turned too much during connection. At least one of the locking lugs can be provided with a stopper. The stopper prevents the nut from being turned too much during connection.
Vulstene kan være utformet med en skråkant for å påføre mutteren større aksialkraft ved sammenføyning. Låseknastene kan være utformet med en skråkant for å påføre mutteren større aksialkraft ved sammenføyning. The beads can be designed with a beveled edge to apply greater axial force to the nut when joining. The locking lugs can be designed with a beveled edge to apply greater axial force to the nut when joining.
En tetning mellom den første koplingsdelen og den andre koplingsdelen kan utgjøres av en gummi- eller kunstmaterialpakning. Rørkoplingen kan i en alternativ utførelses-form være forsynt med en metallpakning mellom den første koplingsdelen og den andre koplingsdelen for å oppfylle gjeldende eller fremtidig regelverk for enkelte ope-rasjoner. Rørkoplingen kan i en ytterligere alternativ utførelsesform være forsynt med en tetning av et gummi- eller kunstmaterialpakning i en posisjon og en metallpakning i en annen posisjon mellom den første koplingsdelen og den andre koplingsdelen. A seal between the first coupling part and the second coupling part can be formed by a rubber or synthetic material gasket. In an alternative embodiment, the pipe connection can be provided with a metal gasket between the first connection part and the second connection part in order to meet current or future regulations for certain operations. In a further alternative embodiment, the pipe connection can be provided with a seal of a rubber or synthetic material seal in one position and a metal seal in another position between the first connection part and the second connection part.
Rørkoplingen kan være utformet med et låselegeme som er innrettet til å kunne befinne seg i korrekt posisjon når rørkoplingen er korrekt sammenkoplet. Foruten å låse rørkoplingen og derved forhindre rørkoplingen fra utilsiktet å løsne, indikerer låselegemet, når det befinner seg i sin korrekte posisjon, at rørkoplingen er klar til bruk. The pipe connection can be designed with a locking body which is designed to be able to be in the correct position when the pipe connection is correctly connected. In addition to locking the pipe fitting and thereby preventing the pipe fitting from accidentally loosening, the locking body, when in its correct position, indicates that the pipe fitting is ready for use.
Rørkoplingen kan være forsynt med en kanal som forløper fra den andre koplingsdelens utside og munner ut mellom tetninger, idet kanalen er innrettet til å kunne trykksettes. Rørkoplingens tetninger kan derved trykkprøves før rørkoplingen monteres inn i tilstøtende utstyr. The pipe connection can be provided with a channel that extends from the outside of the second connection part and opens out between seals, the channel being designed to be pressurized. The seals of the pipe connection can thereby be pressure tested before the pipe connection is fitted into adjacent equipment.
Anordningen ifølge oppfinnelsen tilrettelegger for en forenklet og mindre strevsom sammenkoplings- og demonteringsoperasjon i forhold til kjente rørkoplinger av denne art. The device according to the invention facilitates a simplified and less strenuous connection and disassembly operation compared to known pipe connections of this kind.
I det etterfølgende beskrives et eksempel på en foretrukket utførelsesform som er anskueliggjort på medfølgende tegninger, hvor: Fig. 1 viser i lengdesnitt en rørkopling ifølge oppfinnelsen i sammenkoplet posisjon; Fig. 2 viser perspektivisk en mutter med låseknaster; Fig. 3A-B viser perspektivisk en andre koplingsdel med vulster i to utførelsesformer; In what follows, an example of a preferred embodiment is described which is visualized in the accompanying drawings, where: Fig. 1 shows a longitudinal section of a pipe coupling according to the invention in the connected position; Fig. 2 shows a perspective view of a nut with locking lugs; Fig. 3A-B show in perspective a second coupling part with beads in two embodiments;
og and
Fig. 4 viser det samme som i fig. 1, men i en annen utførelsesform. Fig. 4 shows the same as in fig. 1, but in a different embodiment.
På tegningene betegner henvisningstallet 1 en rørkopling for sammenkopling av et første rør 2 med et andre rør 4. I den viste utførelsesformen er en første koplingsdel 6 på i og for seg kjent måte koplet til det første røret 2, mens en andre koplingsdel 8 utgjør en del av det andre røret 4. Koplingsdelene 6, 8 holdes i sammenkoplet posisjon av en mutter 10. In the drawings, the reference number 1 denotes a pipe connection for connecting a first pipe 2 with a second pipe 4. In the embodiment shown, a first connection part 6 is connected to the first pipe 2 in a manner known per se, while a second connection part 8 forms a part of the second pipe 4. The connecting parts 6, 8 are held in the connected position by a nut 10.
Den første koplingsdelen 6 er utformet med et sylindrisk tetningsparti 12 som er forsynt med minst en tetning 14, her i form av et spor med en O-ring. Tetningspartiet 12 rager inn i en boring 16 i den andre koplingsdelen 8 hvor tetningen 14 ligger tettende an mot boringen 16. The first coupling part 6 is designed with a cylindrical sealing part 12 which is provided with at least one seal 14, here in the form of a groove with an O-ring. The sealing part 12 projects into a bore 16 in the second coupling part 8, where the seal 14 lies sealingly against the bore 16.
En brystning 18 på den første koplingsdelen 6 utgjør et anlegg for mutteren 10. A parapet 18 on the first coupling part 6 constitutes a facility for the nut 10.
Den andre koplingsdelen 8 er utvendig forsynt med et antall vulster 20 som rager ut fra den andre koplingsdelens 8 utvendige sylindriske mantelflate 22. Vulstene 20 er fordelt omkring den andre koplingsdelen 8. The second coupling part 8 is externally provided with a number of beads 20 which protrude from the second coupling part 8's external cylindrical mantle surface 22. The beads 20 are distributed around the second coupling part 8.
Mutteren 10, som i bruksstilling er innrettet til å kunne ligge an mot brystningen 18, er innvendig forsynt med et antall fordelte låseknaster 24. Låseknastene 24 er utformet til å kunne forskyves mellom nærliggende vulster 20 under en sammenkoplings-operasjon, hvoretter en dreining av mutteren 10 om rørkoplingens 1 senterakse 26 relativt den andre koplingsdelen 8, bringer låseknastene 24 i inngrep med respektive vulster 20 slik det er indikert i fig. 1 og 4. Minst én av låseknastene 24 er forsynt med en stopper 28 for å sikre at mutteren 10 stanser i korrekt posisjon. I en alternativ ut-førelsesform som vist i fig. 3B, kan minst én av vulstene 20 være forsynt med en stopper 28' for å sikre at mutteren 10 stanser i korrekt posisjon. The nut 10, which in the position of use is arranged to be able to rest against the parapet 18, is internally provided with a number of distributed locking lugs 24. The locking lugs 24 are designed to be able to be displaced between nearby beads 20 during a coupling operation, after which a turning of the nut 10 about the central axis 26 of the pipe coupling 1 relative to the second coupling part 8, brings the locking lugs 24 into engagement with respective beads 20 as indicated in fig. 1 and 4. At least one of the locking lugs 24 is provided with a stop 28 to ensure that the nut 10 stops in the correct position. In an alternative embodiment as shown in fig. 3B, at least one of the beads 20 may be provided with a stopper 28' to ensure that the nut 10 stops in the correct position.
Et låselegeme 30, her i form av en låsedor, som er innrettet til å kunne skyves inn i rørkoplingen 1 når rørkoplingen 1 er korrekt sammenkoplet, forhindrer rørkoplingen 1 fra utilsiktet å kunne løsne. Samtidig vil låselegemet 30, når det er montert, vise at mutteren 10 er i sin låsende bruksstilling. Låselegemet 30 kan være anbrakt i et hull 31 i mutterens 10 endeflate 11, i et hull 32 i en av vulstene 20 og i et hull 32' i låse-knasten 24. Låselegemet 30 kan rage opp over mutterens 10 endeflate 11. A locking body 30, here in the form of a locking mandrel, which is arranged to be able to be pushed into the pipe coupling 1 when the pipe coupling 1 is correctly connected, prevents the pipe coupling 1 from being able to loosen unintentionally. At the same time, the locking body 30, when mounted, will show that the nut 10 is in its locking position for use. The locking body 30 can be placed in a hole 31 in the end face 11 of the nut 10, in a hole 32 in one of the beads 20 and in a hole 32' in the locking knob 24. The locking body 30 can protrude above the end face 11 of the nut 10.
I utførelseseksemplet er det anordnet fire vulster 20 og fire komplementært passende låseknaster 24. Dette bevirker at det er tilstrekkelig å dreie mutteren 10 omtrent førti-fem grader for å bringe mutteren 10 mellom en utløst bruksstilling og en låsende bruksstilling. In the embodiment, four beads 20 and four complementary suitable locking lugs 24 are arranged. This means that it is sufficient to turn the nut 10 approximately forty-five degrees to bring the nut 10 between a released use position and a locking use position.
Rørkoplingen 1 kan være forsynt med en metalltetning 34, se fig. 4. I den viste utfø-relsesform er rørkoplingen 1 utformet med to tetninger 14, 34. I fig. 1 utgjøres de av to tetninger 14, mens de i fig. 4 utgjøres av én tetning 14 og metalltetningen 34. The pipe connection 1 can be provided with a metal seal 34, see fig. 4. In the embodiment shown, the pipe connection 1 is designed with two seals 14, 34. In fig. 1 they consist of two seals 14, while in fig. 4 consists of one seal 14 and the metal seal 34.
En kanal 36 som forløper fra den andre koplingsdelens 8 utside, munner ut mellom tetningene 14, se fig. 1, eller tetningen 14 og metalltetningen 34, se fig. 4. Kanalen 36 kan trykksettes for å teste tetningene 14, 34 før bruk. På i og for seg kjent måte kan kanalen 36 være utformet med ikke viste ventiler, for eksempel for avblødning av trykk. A channel 36 which extends from the outside of the second connecting part 8 opens out between the seals 14, see fig. 1, or the seal 14 and the metal seal 34, see fig. 4. The channel 36 can be pressurized to test the seals 14, 34 before use. In a manner known per se, the channel 36 can be designed with valves not shown, for example for bleeding off pressure.
Når det anvendes metallpakning 34, kan det være nødvendig å utforme låseknastene 24 med en skråkant 38 for å kunne trekke mutteren 10 innover den andre koplingsdelen 8 med større kraft. Tiltrekking av mutteren 10 kan utføres med et verktøy på i og for seg kjent måte. I en alternativ utførelsesform kan vulstene 20 være utformet med en skråkant 38'. When metal gasket 34 is used, it may be necessary to design the locking lugs 24 with a slanted edge 38 in order to be able to pull the nut 10 inwards on the second coupling part 8 with greater force. Tightening of the nut 10 can be carried out with a tool in a manner known per se. In an alternative embodiment, the beads 20 can be designed with a slanted edge 38'.
