OCTG yog dab tsi
Roj Lub Tebchaws Tubular Khoom, lossis OCTG, yog tsev neeg cov khoom siv yeeb nkab siv los tsim thiab ua haujlwm cov roj thiab cov qhov dej. Cov chav kawm tseem ceeb yog casing, tubing, thiab laum yeeb nkab, thiab lawv tau txhais los ntawm API 5CT rau casing thiab tubing thiab API 5DP rau laum yeeb nkab. Casing yog cov yeeb nkab uas txo qis rau hauv qhov drilled borehole thiab cemented nyob rau hauv qhov chaw kom tiv thaiv phab ntsa los ntawm collapsing thiab cais cov formations; tubing yog cov yeeb nkab khiav hauv lub casing uas nqa cov roj, roj, dej, thiab kho cov kua dej mus thiab los ntawm thaj chaw tsim khoom; laum yeeb nkab xa cov kev sib hloov thiab cov kua dej mus rau lub laum me ntsis. Kab yeeb nkab, los ntawm qhov sib txawv, yog cov yeeb nkab siv los thauj cov kua dej uas tsim los ntawm qhov chaw, npog los ntawm API 5L.
Cov Khoom Muag
Tubing yog siv rau kev tsim khoom thiab kev ua haujlwm xws li kev txhaj tshuaj dej thiab cov kua qaub tawg, thiab nws yuav tsum tiv taus lub siab sab hauv thiab cov kua dej corrosive. Casing kab cov borehole thiab nqa cov qauv thiab siab loads ntawm lub qhov dej, nrog nto, nruab nrab, thiab cov hlua ntau lawm nyob ntawm qhov zoo tsim. Drilling yeeb nkab yog cov hlua rotating drills lub qhov, nrog cov phab ntsa hnyav thiab cov cuab yeej sib txuas, thiab nws tau tuav thiab tshuaj xyuas txawv ntawm cov casing thiab tubing. Cov chav kawm raug xaiv los ntawm kev tsim qhov zoo, qhov tob, thiab cov kev pabcuam.
Qib thiab Cov Khoom
Cov qib API 5CT feem ntau yog J55, N80, L80, thiab P110, nrog tus lej muab qhov tsawg kawg nkaus yield zog hauv ksi. J55 yog qib kev lag luam rau qhov ntiav thiab qis - qhov dej siab; N80 muab lub zog nruab nrab; L80 yog ib qho kev tswj hwm- qib tawm los nrog kev txwv hardness rau corrosive thiab hydrogen{11}}sulphide kev pabcuam; thiab P110 yog qib siab - lub zog rau qhov tob, siab - qhov dej siab. Cov qib sib txawv ntawm cov khoom lag luam, kev txwv hardness, thiab tsis kam mus rau sulphide kev nyuaj siab tawg, thiab kev xaiv ua raws li qhov tob tob, siab, thiab corrosivity ntawm cov kua ua kua.
Xaus Kev Sib Tw thiab Kev Sib Txuas
Cov yeeb nkab kawg yog tiav rau cov xov txuas txuas. Sab nraud chim kawg (EUE) thickens cov yeeb nkab kawg ua ntej threading, muab ib tug muaj zog sib koom tes rau tubing; tsis yog- chim siab kawg (NUE) yog siv rau qis- kev pabcuam siab. Cov kev sib txuas muaj xws li API threads thiab premium couplings, uas yog xaiv rau lawv sealing thiab dabtsi yog khoov kev ua tau zoo nyob rau hauv lub qhov dej. Cov couplings, suav nrog EUE, AB hloov kho, tig, thiab tshwj xeeb- hom kev tshem tawm, yog muab nrog cov yeeb nkab, thiab cov pob qij txha hauv tib qib thiab kev sib txuas ua tiav txoj hlua.
Qhov ntau thiab tsawg thiab Accessories
OCTG yog tsim nyob rau hauv API qhov ntau thiab tsawg, nrog cov raj feem ntau muaj los ntawm 2 3/8 nti rau 4 1/2 nti sab nraud txoj kab uas hla thiab casing los ntawm 4 1/2 nti mus rau 20 nti thiab loj dua. Cov phab ntsa tuab thiab hom kev sib txuas yog xaiv rau cov qauv tsim. Accessories muaj xws li cov couplings, xov tiv thaiv, thiab pup pob qij txha, thiab cov hlua yog tsim los ntawm qhov tseeb torque raws li kev sib txuas lus tshwj xeeb.
Kev tsim khoom thiab kev sim
Seamless OCTG yog tsim los ntawm kev tho thiab dov, tom qab ntawd cua sov- kho rau qib, nrog cov xov xaus ua tiav tom qab kev kho cua sov. Txhua qhov sib koom ua ke tau ua tiav tag nrho -ntev thiab kawg- thaj chaw tshuaj xyuas ntawm tus qauv: kev sim hydrostatic, drifting los xyuas qhov kev tshem tawm sab hauv, tag nrho- lub cev thiab xaus ultrasonic lossis electromagnetic tshuaj xyuas, thiab qhov ntsuas qhov ntev ntawm cov xov. Thib peb-kev soj ntsuam tog tuaj yeem npaj tau raws li qhov yuav tsum tau ua, thiab daim ntawv pov thawj zeb sau cov cua sov, cov txiaj ntsig kev siv tshuab, thiab cov txiaj ntsig tshuaj xyuas rau ntau.
Cov lus nug nquag
Q: OCTG sawv rau dab tsi?
Roj Lub Tebchaws Tubular Khoom: lub casing, tubing, thiab laum yeeb nkab siv hauv cov roj thiab cov qhov dej, txhais los ntawm API 5CT thiab API 5DP.
Q: Qhov txawv ntawm casing thiab tubing yog dab tsi?
Casing kab cov borehole thiab yog cemented los tiv thaiv lub cev qhuav dej; tubing khiav hauv lub casing kom nqa cov kua dej uas tsim tau. Ob leeg muaj qhov sib txawv, qhov sib txuas, thiab kev tsim khoom thauj.
Q: Cov qib API 5CT yog dab tsi?
J55, N80, L80, thiab P110, nrog tus lej raws li qhov tsawg kawg nkaus tawm lub zog hauv ksi thiab sib txawv hardness thiab corrosion txwv.
