API 5CT J55 Petroleum Casing Pipe
API 5CT J55 Petroleum Casing Pipe yog dab tsi?
Txhais:J55 yog ib feem ntawmPawg 1Raws li API 5CT specification. Nws yog ib qho qis - mus rau - nruab nrab lub zog steel.
Cov yam ntxwv tseem ceeb:Nws yog ntau yam thiab raug nqi -zoo. Vim tias nws lub zog qis dua piv rau N80 lossis P110, nws yog siv nyob rau hauv ib puag ncig uas tsis muaj kev ntxhov siab lossis lub siab sab hauv.
Kev sib piv:Nws zoo ib yam li QibK55. Thawj qhov sib txawv yog tias J55 muaj qhov tsawg kawg nkaus tensile zog yuav tsum tau (75,000 psi) piv rau K55 (95,000 psi).

API 5CT J55 Kev sib txuas
J55 kav dej feem ntau siv tus qauv API xov profiles, txawm hais tias cov xov zoo tuaj yeem siv tau yog tias thov.
Rau Casing:
STC (Short Thread Coupled):Feem ntau rau J55 vim yog cov ntawv thov dej ntiav.
LTC (Long Thread Coupled):Siv thaum xav tau kev sib koom ua ke ntau dua.
BTC (Buttress Thread Coupled):Siv rau cov hlua hnyav dua los tiv thaiv xov "rub- tawm."
Rau Tubing:
NU (Tsis yog{0}} chim siab):Threaded ncaj qha mus rau lub yeeb nkab kawg.
EUE (Sab Nraud Upset End):Qhov kawg yog thickened ua ntej threading kom muaj zog sib koom ua ke (feem ntau cov tubing kev twb kev txuas).
Kev tshuaj ntsuam xyuas rau J55
J55 ua raws li cov txheej txheem tshuaj xyuas cov txheej txheem rauPSL-1(Product Specification Level 1):
Kev tshuaj xyuas qhov muag:Tshawb xyuas qhov tsis xws luag xws li seams, pits, thiab mechanical puas.
Hydrostatic Test:Txhua qhov sib koom ua ke yog siab- sim nrog dej kom paub tseeb tias muaj kev sib khi.
Dimensional Check:Kev ntsuas sab nraud (OD), Phab Ntsa Thickness, thiab Ntev.
Drift Test:Hla lub mandrel los ntawm cov yeeb nkab kom ntseeg tau tias kev tshem tawm sab hauv rau cov cuab yeej.
Xov Gauging:Txheeb xyuas cov xov hlau lead, taper, thiab qhov siab siv API- ntawv pov thawj ntsuas.
NDT (Tsis yog -Kev Ntsuas Kev Ua Phem):Feem ntau suav nrog Electromagnetic (EMI) lossis Ultrasonic (UT) kuaj txhawm rau txheeb xyuas qhov tsis zoo.

FAQ
Lub zog tawm ntawm API 5CT J55 yog dab tsi?
Qhov tsawg kawg nkaus yield zog ntawm API 5CT J55 casing yog 379 MPa (kwv yees li 55,000 psi), nrog ib tug yield zog ntau yam ntawm 379 rau 552 MPa, ua tau raws li cov neeg kho tshuab cov khoom yuav tsum tau rau cov J55 steel qib teev nyob rau hauv API SPEC 5CT tus qauv.
Dab tsi yog qhov txawv ntawmK55thiab J55?
J55 thiab K55 yog ob qib ntawm nruab nrab -lub zog carbon steel roj casing kav uas tau teev tseg raws li API 5CT tus qauv. Lawv qhov sib txawv tseem ceeb yog raws li hauv qab no:
Mechanical Properties: Ob qib sib koom ua ke ntawm 379-552 MPa; Txawm li cas los xij, K55 muaj lub zog tensile ntawm Greater los yog sib npaug rau 655 MPa-qhov tseem ceeb siab dua J55's Ntau dua lossis sib npaug rau 552 MPa- ua rau muaj kev tiv thaiv zoo dua rau kev nro thiab tawg.
Chemical Composition: Cov ntsiab lus manganese hauv K55 (1.25–1.50%) yog siab dua li hauv J55 (0.85–1.00%). Tsis tas li ntawd, qee qhov K55 variants suav nrog micro- alloying ntsiab- xws li vanadium- kom xa cov kev ua tau zoo.
Kev siv tau: J55 yog tus nqi- qhov kev xaiv zoo tsim nyog rau qhov dej ntiav thiab qis - kev ua haujlwm siab, thaum K55 yog tsim los rau nruab nrab - rau - qhov dej tob thiab siab - qhov chaw siab, muab kev nyab xeeb ntau dua.
Kev hloov pauv: K55 tuaj yeem hloov pauv rau J55; txawm li cas los xij, qhov rov qab tsis tuaj yeem ua tau.
