Bomba la mstari
Inatumika kusambaza gesi, maji na mafuta katika tasnia ya gesi asilia na kadhalika.
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 kutokana na kuporomoka na. kuruhusu maji ya kuchimba visima kuzunguka na uchimbaji kufanyika.Mabomba ya Kuweka Chuma yana ukuta laini na nguvu ya chini ya mavuno ni psi 35,000.
Mirija: Mirija ni bomba linalotumika kwa usafirishaji wa mafuta ghafi na gesi asilia kutoka safu ya mafuta au gesi hadi juu baada ya kuchimba visima kukamilika.Inafanywa ili kuhimili shinikizo linalotokana na mchakato wa uchimbaji.Mirija hutengenezwa kwa njia sawa na casing, isipokuwa kwamba mchakato wa ziada unaojulikana kama "upsetting" hutumiwa kuimarisha mabomba.
