Mwayi wakumtunda wamafuta & gasi pakugulitsa ma valve akhazikika pamitundu iwiri yoyambira: chitsime ndi mapaipi. Zoyambazo nthawi zambiri zimayendetsedwa ndi API 6A Specification for Wellhead and Christmas Tree Equipment, ndipo yotsirizirayi ndi API 6D Specification for Pipeline and Piping Valves.
Wellhead applications (API 6A)
Mwayi wogwiritsa ntchito bwino amayembekezeredwa mokulira kutengera Baker Hughes Rig Count yomwe imapereka chiwongolero chotsogola kumakampani akumtunda amafuta & gasi. Metric iyi idakhala yabwino mu 2017, ngakhale pafupifupi ku North America kokha (onani Tchati 1). Chitsime chodziwika bwino chimaphatikizapo ma valve asanu kapena kuposerapo omwe amakumana ndi API Specification 6A. Mavavuwa nthawi zambiri amakhala ang'onoang'ono apakati pa 1 "mpaka 4" pamitu yam'mphepete mwa nyanja. Ma valve angaphatikizepo valavu yapamwamba ndi yapansi kuti atseke bwino; valavu yamapiko opha poyambitsa mankhwala osiyanasiyana owonjezera kuyenda, kukana dzimbiri, ndi zina; valavu yopangira mapiko otsekera / kudzipatula kwa chitsime kumayendedwe a mapaipi; valavu yotsamwitsa yosinthira kutuluka kwa chitsime; ndi valavu swab pamwamba pa mtengo msonkhano kuti ofukula kulowa mu bowo la chitsime.Mavavu nthawi zambiri amakhala amtundu wa chipata kapena mpira ndipo amasankhidwa makamaka kuti atseke zolimba, kukana kukokoloka kwa madzi, komanso kukana dzimbiri zomwe zimatha kukhala zodetsa nkhawa kwambiri zamafuta omwe amakhala ndi sulfure wowawasa kapena wowawasa. Zindikirani kuti zomwe takambiranazi sizikuphatikiza ma valve a subsea omwe amayang'aniridwa ndi zovuta zambiri zautumiki komanso pakuchedwa kubweza msika chifukwa cha kukwera mtengo kwa kupanga kwa nyanja ya pansi pa nyanja.
