API 6A Casing Head uye Wellhead Assembly
Zvisarudzo zvemusoro wecasing ndezvizvi:
Kubatana kwepasi kwemusoro wecasing kungave API yakatenderedza bhokisi shinda kana API buttress box thread; inogonawo kuva mhando yekubatanidza.
Inogona kupihwa ne weld-inotsigira base plate.
Maside outlet anogona kunge ari shinda yepombi kana kuti yakaturikidzana, yakaturikidzana yekubuda nayo inogadzirwa neshinda yechikadzi yekubatanidza R 1.1/2" vharafu inodzosera kumashure.

Single-stage thread type:
Inogona kugadzirisa marudzi ese etambo yekasi uye kubatana nepamusoro casing kuburikidza nepini * pini nipple, inokurumidza uye nyore kuisa. Iyo casing yekugadzira inogona kumiswa ne mandrel kana slip.
Split double stage type:
Inogona kuturika matatu akaturikidzana, iyo yekumusoro casing inogona kusungirirwa kana kutsvedza mumhando yewelding, uye tekinoroji casing uye casing yekugadzira inogona kunge iri yemhando yekutsvedza kana mandrel mhando.
Slip-type yezasi yekubatanidza casing musoro:
Iyo yekumusoro yekukiya screw inoshandiswa kugadzira iyo inotsvedza zino rinosunga pamusoro pecasing. Uye BT-mhando casing sealing mhete inopiwa, iyo yakanyatsobatanidzwa, yakanakira uye yakavimbika.
Casing musoro ebetsero maturusi
Kupfeka gwenzi
Kupfeka gwenzi kunonyanya kushandiswa kudzivirira musoro wecasing uye mukati memukati sealing surface yemuchinjiko kubva pakukuvadzwa nematurusi ekuchera panguva yekuchera.
Zvishandiso zvinoenderera
Yakashandiswa kuburitsa gwenzi reKupfeka.
Pressure test plug
Iyo pressure test plug iri pabendekete remukati mecasing head spool uye inoedza kusimba kweBOP, drilling spool uye casing musoro kuburikidza nepombi yekuboorera.
