API 6A Casing Head thiab Wellhead Assembly
Cov kev xaiv rau lub taub hau casing yog raws li nram no:
Kev sib txuas hauv qab ntawm lub taub hau casing yog API round box xov lossis API buttress box xov; nws kuj tuaj yeem yog hom kev sib txuas.
Nws tuaj yeem muab tau nrog lub weld-txhawb puag phaj.
Sab qhov hluav taws xob tuaj yeem yog cov raj xa dej los yog cov khoom siv, cov hluav taws xob sab nraud yog machined nrog poj niam xov rau txuas R 1.1/2 "rov qab valve.

Single-theem xov hom:
Nws tuaj yeem ua tiav txhua yam ntawm cov xov tooj thiab txuas nrog lub ntsej muag casing los ntawm tus pin * pin txiv mis, uas yog ceev thiab yooj yim rau nruab. Kev tsim cov casing tuaj yeem raug tshem tawm los ntawm mandrel lossis plam.
Split ob theem hom:
Nws tuaj yeem dai peb txheej ntawm cov casing, lub npoo npoo tuaj yeem ua tau threaded los yog zawv zawg rau hauv vuam hom, thiab cov txheej txheem casing thiab ntau lawm casing tuaj yeem yog hom swb lossis hom mandrel.
Slip-hom hauv qab txuas casing taub hau:
Sab saum toj locking ntsia hlau yog siv los ua tus txhuam hniav clamp rau saum npoo casing. Thiab BT-hom casing sealing nplhaib yog muab, uas txuas ruaj khov, yooj yim thiab txhim khu kev qha.
Casing head auxiliary cuab yeej
Hnav hav txwv yeem
Hnav hav txwv yeem yog siv los tiv thaiv lub taub hau lub taub hau thiab cov kab noj hniav hauv qhov chaw sib khi ntawm tus ntoo khaub lig los ntawm kev puas tsuaj los ntawm cov cuab yeej drilling thaum lub sijhawm ua haujlwm drilling.
Cov cuab yeej txuas ntxiv mus
Siv los tshem tawm Cov Khaub Ncaws Hnav.
Siab test plug
Lub siab ntsuas ntsaws yog nyob rau ntawm lub xub pwg sab hauv ntawm lub taub hau casing thiab kuaj qhov nruj ntawm BOP, drilling spool thiab casing taub hau los ntawm cov yeeb nkab laum.
