amathuba enomtsalane ioli zenyuse & igesi

Amathuba oyile negesi emantla ekuthengisweni vana igxile iintlobo ezimbini zaseprayimari lwezicelo: wellhead kunye umbhobho. I yangaphambili ngokubanzi ilawulwa Ukucaciswa API 6A for Wellhead kunye Christmas Tree Equipment, kwaye yokugqibela yi API 6D Specification for lwemibhobho kunye babetha Ivaluva.
izicelo Wellhead (API 6A)
Amathuba izicelo wellhead ahluhlwa eqikelelweyo zisekelwe Baker Hughes Rig Count leyo inika metric elikhokelayo kwi emantla kushishino oyile negesi. Le metric wajika HIV ngo-2017, nangona phantse kuphela e North America (jonga Chart 1). A wellhead eqhelekileyo iquka izivingco ezintlanu okanye ngaphezulu olukhawulelana 6A API Ukucaciswa. Le valve ngokubanzi ubungakanani omncinane ku ezahlukene 1 "ku-4" ngenxa wellheads eselunxwemeni. Kwemithambo ingaquka ongentla asezantsi master vana ngenxa shutoff kakuhle; isivingco wawubulala iphiko ngentshayelelo kweekhemikhali ezahlukeneyo isixhasi flow, nokumelana, kunye nezinye iinjongo; isivingco imveliso khono shutoff / kwaleli wellhead ukusuka kwinkqubo yombhobho; isivingco ziliminxe ukuba uhlangabezane adjustable lokuhamba equleni; yaye ivelufa swab phezulu wendibano yemithi sokufikelela nkqo kungena yazala kakuhle. Valve ngokubanzi isango okanye ibhola uhlobo kwaye olukhethiweyo ingakumbi shutoff tight, ukumelana flow ukhukuliseko, nokuzabalazela umhlwa enokuba othile ukuba ekrwada ezimuncu okanye iimveliso irhasi emuncu enesiqulatho high nesalfure. Kufuneka kuqatshelwe ukuba ngxoxo ayibabandakanyi kwemithambo Subsea ezo ngokuxhomekeke kwiimeko kude unzima kakhulu inkonzo phezu track imisiwe zokubuyisa kwemarike ngenxa isiseko iindleko eziphezulu kakhulu kwimveliso Subsea.
