Zida Zopangira Mafuta ndi Gasi
Mtengo Wapawiri Wolimba Wa block
Kwa zingwe zamachubu apawiri, mtengo wokhazikika wa block ndi womwe umagwiritsidwa ntchito kwambiri. Zosankha ziwiri zomwe zikuwonetsedwa ndizojambula zofala kwambiri. Ma valve omwe amayendetsa kutuluka kuchokera kumadera akuya, chingwe chachitali, ndi ma valve otsika pamtengo. Ngakhale pali zosiyana ndi msonkhano uno, pokhapokha ngati mtengowo ukuwonekera bwino, tingaganize kuti malo a valve akuwonetsa kugwirizana kwa subsurface.
Zigawo zoyamba za dongosolo lachitsime ndi

Ntchito
· Kupereka njira yoyimitsira casing. (Casing ndi chitoliro chokhazikitsidwa kosatha chomwe chimagwiritsidwa ntchito kuyika dzenje la chitsime kuti muchepetse kuthamanga komanso kupewa kugwa panthawi yoboola).
· Amapereka njira kuyimitsidwa kwa chubu. (Tubing ndi chitoliro chochotseka chomwe chimayikidwa pachitsime chomwe madzi amadutsamo).
• Amapereka njira yotsekera ndikuyika patali pakati pa casing pamwamba pomwe zingwe zambiri zomangira zimagwiritsidwa ntchito.
· Amapereka kuyang'anira kuthamanga ndi kupopera mwayi wopita ku annuli pakati pa zingwe zosiyanasiyana za casing/tubing.
· Amapereka njira yolumikizira choletsa kuphulika pobowola.
· Amapereka njira yolumikizira mtengo wa Khrisimasi kuti agwire ntchito zopanga.
· Amapereka njira yodalirika yopezera bwino.
· Amapereka njira yolumikizira mpope wa chitsime.
Kufotokozera
API 6A, Edition 20, October 2010; Kufotokozera kwa Wellhead ndi Zida Zamtengo wa Khrisimasi
ISO 10423:2009 Zida za Wellhead ndi Mtengo wa Khrisimasi
Nthawi zambiri mitu yabwino imakhala ndi miyeso isanu yazitsime: 2, 3, 5, 10 ndi 15 (x1000) PSI yogwira ntchito. Amakhala ndi kutentha kwapakati pa -50 mpaka +250 madigiri Fahrenheit. Amagwiritsidwa ntchito molumikizana ndi ma gaskets amtundu wa mphete.
Nthawi zambiri mphamvu zokolola zazinthu zimachokera ku 36000 mpaka 75000 PSI.
