Casing
Casing ni bomba la kipenyo kikubwa ambalo hutumika kama kihifadhi miundo kwa kuta za visima vya mafuta na gesi, au visima. Huingizwa kwenye kisima na kuwekwa saruji ili kulinda miundo ya chini ya uso na kisima kisiporomoke na kuruhusu maji ya kuchimba visima kuzunguka na uchimbaji ufanyike.Mabomba ya Kuweka Chuma yana ukuta laini na nguvu ya chini ya mavuno ni psi 35,000.
Well Casing hutumika vile vile sidewall.Viwango na Masharti ya Kiufundi ya Ugavi:API Maalum ya 5CT ISO13680 Daraja: J55, K55, N80-1,N80-Q, L80-1, L80-9Cr,L80-13Cr,C95, P110.Aina za kukanyaga: NUE, EUE, VAM, STC, LTC, BTC, kibali maalum, XC,VAM TOP,VAM MPYA.
Bomba la Kufunga Mafuta: Casings hutumiwa kwa ajili ya kurekebisha ukuta wa kisima au shimo la chini, ambalo lina kipenyo kikubwa, linaweza kugawanywa katika casings ya conductor, casings ya kiufundi na casings ya Mafuta.
Matumizi: Kifuniko cha Kisima hutumika vile vile ukuta wa kando.
