API 5CT OCTG L80 quvurlari yetkazib beruvchisi
Oil Country Tubular Goods qisqa shakli (OCTG) asosan korpus va quvurlarni nazarda tutadi, lekin neft va gazni tashish va qidirishda ishlatiladigan quvur liniyasiga ham tegishli bo'lishi mumkin.
Quduqni burg'ilashda korpus ishlatilgan.Quduqqa korpus qo'yilgan va sementlangan, bu esa burg'ulash yoki ishlab chiqarish jarayonida teshikning yiqilishiga yo'l qo'ymaydi.Quduq tugagandan so'ng, trubka - bu neft va gaz yuzasiga oqadigan quvur.
