I-API 6A yeNtloko yeCasing kunye ne-Wellhead Assembly
Iinketho zentloko yebhokisi zezi zilandelayo:
Udibaniso olusezantsi lwentloko yebhokisi mhlawumbi yi-API engqukuva yebhokisi yomsonto okanye i-API buttress box thread;inokuba ludibaniso lohlobo.
Inokubonelelwa ngesiseko se-weld-support plate.
Iindawo ezisecaleni zisenokuba yimisonto yombhobho okanye iqhina, iqhina elisecaleni lenziwe ngoomatshini ngomsonto obhinqileyo wokuqhagamshela i-R 1.1/2” ivelufa ebuyela umva.
Inkcazo
| Ilinganiswe WP | 21MPa, 35MPa, 70MPa, 105MPa |
| PSL | PSL1,PSL2,PSL3,PSL3G,PSL4 |
| PR | PR1 |
| TC | P, U, L |
| MC | AA,BB,CC,DD,EE,FF |
Uhlobo lomsonto wenqanaba elinye:
Iyakwazi ukucubungula zonke iintlobo zentambo ye-casing kwaye idibanise nomphezulu we-casing ngokusebenzisa i-pin * pin nipple, ekhawulezayo kwaye kulula ukuyifaka.I-casing yemveliso inokunqunyanyiswa yi-mandrel okanye i-slip.
Ukwahlula isigaba esiphindwe kabini:
Iyakwazi ukuxhoma iileya ezintathu ze-casing, i-surface casing inokudityaniswa okanye i-sliding ibe yi-welding type, kunye ne-casing yobugcisa kunye ne-casing yemveliso ingaba yohlobo lwe-slip okanye uhlobo lwe-mandrel.
Isiliphu-uhlobo olusezantsi loqhagamshelo lwentloko yebhokisi:
Isikrufu sokutshixa esingasentla sisetyenziselwa ukwenza i-slip tooth clamp i-surface casing.Kwaye i-BT-type casing sealing ring inikezelwa, edityaniswe ngokuqinileyo, ilula kwaye inokwethenjelwa.
Casing intloko izixhobo ezincedisayo
Ukunxiba ihlathi
Ukunxiba i-bush isetyenziselwa ukukhusela intloko ye-casing kunye ne-internal cavity seal surface yomnqamlezo ukuba wonakaliswe zizixhobo zokomba ngexesha lemisebenzi yokomba.
Izixhobo eziqhubekayo
Isetyenziselwa ukukhupha ityholo lokunxiba.
Iplagi yovavanyo loxinzelelo
Iplagi yokuvavanya uxinzelelo ibekwe kwigxalaba langaphakathi le-spool yentloko ye-casing kwaye ivavanya ukuqina kwe-BOP, i-drilling spool kunye nentloko ye-casing ngokusebenzisa umbhobho we-drill.
