API 16C Choke & Uraya akawanda

Tsanangudzo Pfupi:

Choke manifold ndiyo inodiwa midziyo yekudzora kick uye kushandisa kudzvanya kudzora tekinoroji yemafuta uye gasi matsime. Kana iyo blowout preventer yakavharwa, imwe casing pressure inodzorwa nekuvhura nekuvhara throttle valve kuchengetedza gomba rezasi pressure yakakwira zvishoma pane yekuumbwa kwekumanikidza, kuitira kudzivirira kuumbwa kwemvura kuyerera ichipinda mutsime mberi. Pamusoro pezvo, kukachidzwa kwakawanda kunogona kushandiswa kudzikamisa kudzvanywa kwekuvhara mukati. Kana dzvinyiriro iri mutsime ikakwira kusvika painogumira, inoshandiswa kuvhuvhuta kudzivirira musoro wetsime. Kana tsime rekumanikidza rinowedzera, mvura iri mugomba inogona kusunungurwa kudzora casing pressure nekuvhura nekuvhara throttle valve (manual inogadziriswa, hydraulic uye yakagadziriswa). Kana iyo casing pressure yakakwira zvakanyanya, inogona kuvhuvhuta yakananga kuburikidza nevhavha yegedhi.
