API 6A Casing Head ndi Wellhead Assembly

Kufotokozera Kwachidule:

Chipolopolo choponderezedwa chimapangidwa ndi chitsulo chopangidwa ndi alloy chokhala ndi mphamvu zambiri, zolakwika zochepa komanso mphamvu zonyamula mphamvu.

Mandrel hanger amapangidwa ndi forgings, zomwe zimatsogolera ku kunyamula kwakukulu komanso kusindikiza kodalirika.

Zigawo zonse zachitsulo za slip hanger zimapangidwa ndi chitsulo chopangidwa ndi alloy. Mano otsetsereka ndi carburized ndi kuzimitsidwa. Mapangidwe apadera a mawonekedwe a dzino ali ndi zizindikiro za ntchito yodalirika komanso mphamvu yobereka kwambiri.

Valavu yokhala ndi zida imatenga tsinde losakwera, lomwe lili ndi torque yaing'ono yosinthira komanso ntchito yabwino.

Chopachikidwa chamtundu wa slip ndi hanger yamtundu wa mandrel zitha kusinthidwa.

Njira yopachikika pa casing: mtundu wa slip, mtundu wa ulusi, ndi mtundu wotsetsereka wowotcherera.

Titumizireni imelo

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Zosankha za mutu wa casing ndi izi:

Kulumikizana pansi kwa mutu wa casing mwina ndi API yozungulira bokosi ulusi kapena API buttress box thread; itha kukhalanso mtundu kugwirizana.

Itha kuperekedwa ndi mbale yoyambira yolumikizira weld.

Zotengera zam'mbali zitha kukhala ulusi wa mapaipi kapena zopindika, zotuluka m'mbali zimapangidwa ndi ulusi wachikazi polumikiza R 1.1/2" valavu yobwerera.

Casing Head-Threaded kapena Welded Pansi

Mtundu wa ulusi wagawo limodzi:

Itha kukonza ulusi wamitundu yonse ndikulumikizana ndi chotchingira chapamwamba kudzera pa pin * pin nipple, yomwe ili yachangu komanso yosavuta kuyiyika. Chophimba chopangira chikhoza kuyimitsidwa ndi mandrel kapena slip.

Gawani magawo awiri:

Itha kupachika zigawo zitatu za casing, choyikapo chapamwamba chimatha kukulungidwa kapena kutsetsereka mumtundu wowotcherera, ndipo chotengera chaukadaulo ndi chopangira chopangira chikhoza kukhala chamtundu wa slip kapena mandrel.

Mutu wolumikizira pansi wolumikizira:

Chophimba cham'mwamba chotsekera chimagwiritsidwa ntchito kupangitsa kuti mano otsetsereka atseke m'bokosi. Ndipo mphete yosindikizira yamtundu wa BT imaperekedwa, yomwe imalumikizidwa mwamphamvu, yabwino komanso yodalirika.

Zida zothandizira mutu wa casing

Kuvala chitsamba

Kuvala chitsamba kumagwiritsidwa ntchito makamaka kuteteza mutu wa casing ndi mkatikati mwa dzenje losindikiza pamwamba pa mtanda kuti zisawonongeke ndi zida zobowola panthawi yoboola.

Zida zopitilira

Amagwiritsidwa ntchito potulutsa chitsamba Chovala.

Pressure test plug

Pulagi yoyezetsa kuthamanga ili paphewa lamkati la spool ya mutu wa casing ndikuyesa kulimba kwa BOP, kubowola spool ndi mutu wa casing kudzera papaipi yobowola.
