Lub ntsiab
API 5ct P110 hais txog qib tshwj xeeb ntawm seamless steel yeeb nkab qauv los ntawm covMiskas lub koom haum (API)Cov. Nws yog feem ntau siv hauv cov roj thiab roj kev lag luam rauZoo casing thiab tubing.
API spec 5ct:Nov yog pab txhawb nqa cov npe "casing thiab tubing." Nws txhais cov txheej txheem kev mob, qhov loj me, kev ua kom muaj kev thev naus laus zis, thiab kev kuaj mob rau cov kav hlau siv hauv cov dej hlau.
P110:Nov yog tusQib kev tsim.
"P"Sawv rau "PIPE cov khoom siv nyob qib. "
"110"kos npe rau lubYam tsawg kawg nkaus xwb ZogNtawm cov yeeb nkab, uas yog 110,000 psi (phaus ib square nti). Hauv cov koog metric, qhov no yog kwv yees li 758 MPA (megapStascals).
Cov yam ntxwv tseem ceeb ntawm qib P110
1. Cov Khoom Siv Neeg Kho Tshuab
Qhov no yog qhov tseem ceeb tshaj plaws ntawm qib P110.
| Ntiag tug | Yam tsawg kawg nkaus yuav tsum tau ua | Sau ntawv |
|---|---|---|
| Paib lub zog | 110,000 psi (758 MPA) | Kev ntxhov siab thaum cov khoom pib deform plastically. Nov yog cov cuab yeej txhais. |
| Lub zog tensile | 125,000 psi (862 mpa)lub min | Qhov siab tshaj plaws kev ntxhov siab cov khoom tuaj yeem tiv thaiv thaum tab tom ncab. |
| Kev nyuaj | Ntau tshaj plaws 295 HBW (Brinell) lossis 31 hrc (rockwell c) | Kev siv tawv tawv txwv yog qhov tseem ceeb los tiv thaiv sulfide kev ntxhov siab tawg (SSC) hauv cov chaw pabcuam qaub.Tus Qauv P110 tsis pom zoo rau Sour kev pabcuam. |
2. Tshuaj lom neeg sib xyaw
Thaum API 5ct tso cai rau qee qhov kev hloov kho tshiab rau cov kws tsim khoom lag luam kom ua tiav cov neeg kho tshuab uas xav tau, muaj xws li:
Cov pa roj carbon (c): 0.25 - 0.35%
Manganese (MN): 1.00 - 1.50%
Phosphorus (p):Tsawg dua los yog sib npaug rau 0.020% (max)
Sulphur (s):Tsawg dua los yog sib npaug rau 0.015% (max)
Lwm cov ntsiab xws li chromium (CR), Molybdenum (mo), thiab npib tsib) yuav muab ntxiv rau txhim kho lub zog thiab cov tawv nqaij tawv.
3. Kev kho cua sov
P110 yog aquenched thiab tempered (Q & T) hlauCov. Qhov txheej txheem thermal no yog qhov tseem ceeb rau kev ua tiav nws lub zog siab thiab tawv:
Quenching:Cov yeeb nkab yog rhuab mus rau qhov kub thiab txias thiab tom qab ntawd sai sai (piv txwv li, hauv dej). Qhov no tsim ib qho nyuaj heev tab sis brittle qauv (Martensite).
Tempering:Qhov quav quenched yog ces reheathed rau ib qho kub tsawg dua thiab txias. Cov txheej txheem no txo cov brittleness thiab nce nruj zuj zus thaum tswj lub zog siab.
Cov kev qhia tshwj xeeb thiab qhov ntev
P110 kav yog tsim hauv cov qauv ntau raws li txhais los ntawm API 5ct. Cov tsis muaj xws li:
Hom:Seamless (xaiv raws li "-s" hauv cov khoom lag luam tag nrho cov khoom lag luam, piv txwv li, p110-1).
Od (sab nraud ntawm lub taub):Ranges los ntawm kwv yees li 2-3 / 8 "txog 20".
Wt (phab ntsa tuab):Yuav sib txawv raws li qhov poob phaus ib txhais ko taw (piv txwv li, L-80, N-80, P-110 yog cov qib kawm uas muaj kev sib txawv nrog cov nyom tib yam rau tib OD).
Xov:Muaj peev xwm muab nrog ntau hom api xov (eg, api buttress, eci puag ncig, lossis hwm cov kev sib txuas los ntawm cov tuam ntxhab nyiam VAM, Hydril, thiab lwm yam).
Cov Ntawv Thov
P110 Casing yog siv rau hauv nruab nrab thiab cov hlua sib xyaw hauv cov roj thiab roj ua kom muaj kev kub siab thiab muaj cov neeg kho tshuab siab.
Nruab nrab casing:Tiv thaiv cov qauv tsis muaj zog los ntawm kev ntsuas siab dua tau ntsib ntawm ntau dua qhov tob.
Ntau lawm Casing:Txoj hlua ntawm cov yeeb nkab uas los ntawm cov roj uas siv roj lossis roj. Nws yuav tsum tau tiv thaiv cov peev txheej siab thiab cov khoom siv ua tiav thiab cov khoom siv tsim khoom.
Cov kev txiav txim tseem ceeb thiab kev txwv
Qaub kev pabcuam (H₂S ib puag ncig): Tus Qauv P110 feem ntau tsis haum rau cov kab ke muaj cov roj hydrogen sulfide (h₂s).Nws lub siab tawv ua rau nws raug rau sulfide kev ntxhov siab tawg (SSC). Rau cov kev pab cuam hauv cov kev pab cuam tshwj xeeb uas muaj kev tswj nruj heevC110(uas muaj tib lub zog tab sis ib qho siab tshaj plaws ntawm 275 HBW / 29 HRC) lossisL80Hom 1 & 9 (uas muaj lub zog qis ntawm 80,000 psi tab sis zoo ssc tsis kam) yog siv.
Cov khoom lag luam qib tshwj xeeb (PSL):API 5CT muaj ob daim PSLS:
PSL-1:Cov qauv yuav tsum tau ua.
PSL-2:Kev tsim kho ntau dua rau cov tshuaj lom neeg, muaj kev sib raug zoo (charpy cuam tshuam kev xeem), thiab kev sim ua tsis tau zoo. P110 muaj nyob rau hauv ob qho tib si PSL-1 thiab PSL-2.
Tsis yog rau Drilling:API 5CT Yeeb (Casing thiab tubing) tsis yog tsim los tiv thaiv torsional thiab dabtsi yog khoov kev ntxhov siab ntawm kev drilling. Txog Drilling,API spec 5dp (laum yeeb nkab)yog siv.
