Cov yam ntxwv ntawm API 5CT R95 Casing & Tubing
Lub zog Advantage:Lub 95 ksi yield zog yog kwv yees li 18% siab dua L80 / N80, muab superior zog thiab tensile kuj.
Yuav tsum tau kho cua sov:Tsis zoo li N80-1, R95 yuav tsum tau quenched & Tempered. Qhov no ua kom muaj cov qauv hlau zoo dua qub thiab cov khoom siv kho tshuab ruaj khov.
Tus nqi siab -Efficiency:Hauv qhov dej uas sab saum toj - cov kev pabcuam qaub qaub (xws li T95) tsis tas yuav tsum tau tab sis muaj zog siab, R95 yog qhov kev xaiv pheej yig dua li P110.
Txhim kho toughness:Vim yog kev tswj hwm tshuaj nruj dua thiab cov txheej txheem Q&T, R95 muaj kev cuam tshuam zoo dua rau qhov kub thiab txias piv rau N80.
Daim ntawv thov ntawm API 5CT R95 Seamless Oil Pipe
Nruab nrab-Deep Wells:Qhov zoo tshaj plaws rau cov qhov dej nrog qhov tob ntawm 3,500 txog 5,000 meters qhov twg lub qhov siab siab siab.
Qab zib / Tsis yog -Sour Environments:Ua tau zoo nyob rau hauv qhov dej tsis muaj H2S lossis nrog cov concentrations tsawg heev uas qhov kev pheej hmoo corrosion tsawg heev.
Siab -Hloov Formations:Siv los ua cov txheej txheem los yog cov khoom tsim los tiv thaiv kev tsim kom muaj kev sib tsoo siab.
Directional & Kab rov tav Wells:Lub zog yield zog pab tswj cov axial loj loads ntau nyob rau hauv kab rov tav drilling seem.
