Maelezo ya bidhaa
Casing na neli inayotumika sana kwa mafuta na gesi hukua, Casing na neli ni sehemu muhimu katika tasnia ya mafuta na gesi inayotumika kwa uchimbaji na usafirishaji wa hidrokaboni (mafuta na gesi asilia) kutoka kwa hifadhi za chini ya ardhi hadi juu ya uso.Wanatekeleza majukumu muhimu katika kuhakikisha usalama, uadilifu, na ufanisi wa shughuli za uchimbaji na uzalishaji.
Mirija ni aina ya bomba linalotumika kuhamisha mafuta ghafi na gesi asilia kutoka safu ya mafuta au safu ya gesi hadi ardhini baada ya kuchimba visima kukamilika.Mirija inaweza kuruhusu shinikizo linalozalishwa wakati wa mchakato wa uchimbaji.Mirija inayozalishwa kwa njia sawa na casing, lakini mchakato unaoitwa "upsetting" unahitajika zaidi ili kuimarisha bomba la neli.
Casing hutumika kulinda visima ambavyo vimechimbwa ardhini kwa ajili ya mafuta.Inatumika sawa na bomba la kuchimba visima, mabomba ya kisima cha mafuta pia huruhusu shinikizo la mvutano wa axial, hivyo chuma cha ubora wa juu kinahitajika.Casings za OCTG ni mabomba makubwa ya kipenyo ambayo yanawekwa kwa saruji kwenye shimo la kisima.
