API 5CT P110yog ib qib siab -lub zog steel qib rau cov roj thiab roj qhov dej, tsim los siv covquenching thiab tempering (Q & T)txheej txheem nrog qhov tsawg kawg nkaus tawm lub zog ntawm110,000 psi (758 MPa). Tsim los rausib sib zog nqus, ultra- tob, thiab siab - ib puag ncig siab, nws muab cov khoom siv zoo tshaj plaws -cov kabmob muaj peev xwm thiab kev sib tsoo tsis zoo los txhawb qhov hnyav hnyav ntawm cov hlua ntev ntev.
Thaum nws yog "cov neeg ua haujlwm" rau cov khoom qab zib (tsis yog- qaub), nws qhov hardness siab thiab tsis muaj qhov siab tshaj plaws hardness txwv ua rau nws muaj kev cuam tshuam rau nkig tsis ua haujlwm hauv ib puag ncig uas muajHydrogen sulfide (H2S); yog li ntawd, nws yogtsis haum rau daim ntawv thov kev pabcuam qaub.
Kev xaiv ntawm kev sib txuas rauP110nyob ntawm tag nrho covzoo qhov tob, siab, thiab ib puag ncig puag ncig. Vim tias P110 yog qib siab - lub zog siv nyob rau hauv ib puag ncig nyuaj, kev sib txuas yuav tsum muaj peev xwm ua tau raws li kev ua tau zoo ntawm cov yeeb nkab lub cev.

API BTC (Butter Threaded thiab Coupled)
BTCyog qhov feem ntau "standard" kev twb kev txuas rau P110 casing.
Vim li cas BTC?Tsis zoo li STC lossis LTC xov, cov duab trapezoidal ntawm Buttress xov muab ntau duatensile zog(rub- tawm tsis kam). Txij li thaum P110 feem ntau siv nyob rau hauv qhov tob tob qhov twg cov hlua casing hnyav heev, BTC yuav tsum tau los txhawb qhov hnyav.
Qhov zoo tshaj plaws rau:Sib sib zog nqus ntsug qhov dej nrog siab axial loads tab sis nruab nrab siab.
Kev txwv:Nws tsis yog "gas- nruj." Nws tso siab rau cov xov xov sib txuas (dope) kom kaw.
Hwm Kev Sib Txuas (Tshooj Tshwj Xeeb)
Rau ntau daim ntawv thov P110, tus qauv API BTC tsis txaus. Hwm kev sib txuas (xws liVAM®, TenarisHydril, lossis tus tswv "Gas{0}}Tight" xov) feem ntau siv.
Vim li cas Premium?
Hlau -rau- Hlau Seal:Kev sib txuas hwm zoo muab 100% roj- nruj seal, uas yog tsim nyog rau siab - cov roj qhov dej siab.
Siab Torque:Nyob rau hauv kab rov tav los yog shale qhov dej (qhov twg fracking tshwm sim), cov yeeb nkab yuav tsum tau tig. Cov xov hwm zoo tuaj yeem tuav lub siab torque xav tau rau cov haujlwm no.
Flush/Semi-Flush:Yog tias lub qhov dej nqaim (slim{0}} qhov), cov kev sib txuas hwm zoo muaj qhov profile me dua li cov qauv BTC txuas.
Qhov zoo tshaj plaws rau:Siab -cov qhov dej siab siab, kab rov tav / sab nraud, sab nraud drilling, thiab thermal (SAGD) qhov dej.
Yuav ua li cas yog STC thiab LTC?
STC/LTCtsis tshua muaj siv rau P110. Cov xov no muaj ntau dua rau cov qib qis xws li J55 lossis K55. Siv STC / LTC ntawm P110 yeeb nkab tsim "tsis muaj zog txuas," raws li kev sib txuas yuav ua tsis tau ntev ua ntej cov yeeb nkab lub cev mus txog nws qhov kev txwv.

FAQ
P110 casing specification yog dab tsi
API 5CT P110yog lub siab -lub zog casing specification tsim rau qhov sib sib zog nqus thiab siab - qhov dej siab. Cov ntsiab lus tseem ceeb muaj xws li:
Yield zog:110,000 - 140,000 psi (758 - 965 MPa).
Tensile zog:Yam tsawg kawg 125,000 psi ({2}} MPa).
Kev kho cua sov:Yuav tsum tauQuenched thiab Tempered (Q & T)rau superior toughness.
Daim ntawv thov:Qhov zoo tshaj plaws rau txoj hlua sib sib zog nqus, hnyav hauv cov dej uas tsis yog- qaub; nws yogtsis yogtiv taus H2S (Sour Service).
Xim Code:Qhia los ntawm adawb bandntawm cov yeeb nkab lub cev thiab coupling.
Dab tsi yog qhov txawv ntawm casing threads?
Casing threads feem ntau muab faib ua ob pawg:API Standard ConnectionsthiabHwm Kev Sib Txuas. Ntawm no yog ib qho yooj yim tawg:
1. API Standard Connections (Common & Nqis -zoo)
STC (Short Threaded thiab Coupled):Ib qho 8- cov xov sib txuas siv rau qhov dej ntiav, qhov dej tsis tshua muaj siab. Nws yog qhov kev lag luam tshaj plaws tab sis muaj lub zog qis tshaj plaws.
LTC (Long Threaded thiab Coupled):Kuj tseem muaj 8- xov sib txuas tab sis ntev dua STC. Nws muaj zog nro zoo dua thiab yog dav siv rau nruab nrab qhov tob qhov dej.
BTC (Butter Threaded thiab Coupled):Nta cov duab trapezoidal (square-ish) xov zoo. Nws muab lub zog tensile siab thiab yog tus qauv xaiv rau cov qhov dej sib sib zog nqus thiab cov hlua hnyav hnyav.
2. Kev sib txuas hwm (High Performance)
Hlau -rau- Hlau Seal:Tsis zoo li API threads uas tso siab rau "xov dope" los kaw, kev sib txuas hwm zoo siv lub foob hlau rau100% gas- nrujkev ncaj ncees.
Nta:Tsim los rau cov xwm txheej tsis zoo, xws li siab - lub siab roj qhov dej, kab rov tav drilling (siab torque), thiab cov haujlwm sab nrauv.
Piv txwv:VAM® series, TenarisHydril, thiab ntau yam "Tshooj Tshwj Xeeb" los ntawm sab saum toj -tier mills.
