J55 K55 N80 Yog 'trubkasi va korpusli po'lat quvur
Neft qobig'i - burg'ulash jarayoni va tugagandan so'ng butun neft qudug'ining normal ishlashini ta'minlash uchun neft va gaz quduqlarining devorlarini qo'llab-quvvatlash uchun ishlatiladigan po'lat quvur.Har bir quduq turli burg'ulash chuqurliklari va geologik sharoitlariga ko'ra bir necha qatlamli qobiqlardan foydalanadi.Qopqoq quduqqa tushirilgandan so'ng tsement sementlash qo'llaniladi.Neft quvurlari va burg'ulash quvurlaridan farqli o'laroq, uni qayta ishlatish mumkin emas va bir martalik sarflanadigan materialdir.Shunday qilib, korpus iste'moli barcha neft quduqlari quvurlarining 70% dan ortig'ini tashkil qiladi.
