API 5CT korpus trubkasi

Korpus - bu katta diametrli quvur bo'lib, u quduqning yaqinda burg'ilangan qismiga yig'iladi va kiritiladi va odatda
tsement bilan o'rnatiladi. Va biz H40, J55, K55 sinfidagi 4-1/2''-20'' dan turli xil choksiz korpuslarni taqdim etamiz,
N80, L80, C95, P110 va boshqalar. Korpus uzunligi diapazoni R1, R2, R3, BTC, LTC, STC iplari bilan. Kuchga qarab
po'lat korpusni har xil po'lat po'latdan foydalangan holda turli po'lat navlarga, chuqur quduqqa bo'lish mumkin. Korroziy muhitda
Bundan tashqari, korpusning o'zi korroziyaga chidamliligini talab qiladi. Murakkab geologik sharoitda joy ham korpus so'radi
qulashga qarshi ko'rsatkichga ega.
