General
- Raws li API 5CT tus qauv, cov khoom siv hlau siv los ua cov yeeb nkab billet yuav tsum tau txais kev kho cov nplej. Cov hlau no yuav tsum muaj ib lossis ntau dua cov khoom ua kom zoo, xws li ib qho nyiaj ntawm txhuas, niobium, vanadium, los yog titanium, thiaj li hais tias cov austenite nplej ntawm steel Grain refinement.
- Cov kav dej xa khoom yuav tsum tau tsim hauv hom seamless lossis EW hom.
- Couplings, coupling stock, thiab coupling cov ntaub ntawv yuav tsum seamless.
- Cold-draw tubing yeeb nkab yuav tsum tau kho kom sov kom zoo; txwv tsis pub, nws tsis tau txais.
- Casing thiab tubing cov ntaub ntawv txuas yuav tsum yog cov kav dej seamless tshwj tsis yog lwm hom tau teev nyob rau hauv qhov kev txiav txim.
Kev kho cua sov
Txoj kev kho cua sov rau API 5CT casing thiab tubing yog qhov tseem ceeb ntawm qhov sib txawv ntawm txhua qib. Cov khoom lag luam uas xav tau kev kho cua sov yuav tsum tau ua kom lub cev tag nrho thiab kev kho cua sov tag nrho. Cov khoom siv kub-kho ntxhov siab yuav tsum tau kho cua sov raws li nws lub cev tag nrho thiab ntev ntev tom qab ntxhov siab.
Ib qho kev sib cais ntawm cov cua sov-kho coupling dawb paug tau txais. Yog hais tias qhov kub thiab txias yog siab tshaj qhov kub tseem ceeb ntawm cov hlau kho thiab cov yeeb nkab yog cua txias, nws yuav tsum tau normalized.
Nyob rau hauv cov ntaub ntawv ntawm welding hom, weld seam yuav tsum tau kho cua sov rau qhov tsawg kawg nkaus kub ntawm 540 degree (1000 degree F), los yog ib tug tej yam kev kho mob yuav tsum tau siv los ua kom tsis muaj untempered martensite qauv nyob rau hauv lub vuam.
N80 Hom 1 thiab Hom Q
Steel qib N80 hom 1 cov khoom yuav tsum tau normalized los yog normalized thiab tempered ntawm qhov kev xaiv ntawm cov chaw tsim tshuaj paus.
N80Q steel-qib cov khoom yuav tsum tau quenched thiab tempered.
R95
R95 steel qib yuav tsum quenched thiab tempered.
L80
Thaum tempered ntawm kub qis dua 620 degree (1150 degree F), qib L80 qib 13 Cr tej zaum yuav embrittled.
Ncaj ncaj
R95
R95 casing thiab tubing yuav tsum tsis txhob ncab lossis nthuav dav ua haujlwm txias tom qab qhov kawg tempering, tshwj tsis yog rau kev ua haujlwm txias uas tsim nyog rau kev ncaj ncaj thiab tsis pub ntau tshaj 3% ntawm compression txias ua haujlwm.
M65 thiab L80
Cov khoom siv hlau qib M65 thiab L80 yuav tsum tsis txhob ua haujlwm txias tom qab kev kho cua sov kawg nkaus tshwj tsis yog rau kev ua haujlwm txias uas yuav tsum tau ua kom ncaj ncaj.
C90 thiab T95
C90 thiab T95 cov khoom tuaj yeem ua kom txias-rotated ncaj, tab sis cov yeeb nkab yuav tsum tau muab tso rau qhov kub ntawm qhov tsawg kawg nkaus ntawm 480 degree (1000 ° F) degrees rau kev ntxhov siab tom qab straightening. Lub teeb gag straightening rau steel qib C90 thiab T95 cov khoom raug tso cai yog tias tsim nyog.
C110
Yog tias tsim nyog, cov khoom yuav tsum tau txias-rotated straightened thiab tom qab kev ntxhov siab-relieved ntawm kub ntawm 30 degree mus rau 55 degree (50 degree F mus rau 100 degree F) hauv qab no qhov kawg teev tempering kub, los yog kub-rotated straightened ntawm kub tsis ntau tshaj. 165 degree (300 degree F) hauv qab qhov kawg teev tempering kub. Yog tias tsim nyog, nws raug tso cai ua lub teeb gag straightening.
Q125
Gag-press straightening los yog kub-rotating straightening yuav ua tau rau straightening, tab sis qhov kub ntawm qhov kawg ntawm lub rotary straightening yuav tsum tsis txhob tsawg tshaj li 400 degree (750 degree F) (tshwj tsis yog qhov kub siab tshaj qhov tsawg kawg nkaus yog teev nyob rau hauv qhov kev txiav txim). Yog tias txoj kev kub rotary straightening tsis tuaj yeem siv, cov khoom kuj tseem tuaj yeem ua kom txias-tso ncaj, tab sis qhov kev ntxhov siab yuav tsum tau ua ntawm 510 degree (950 degree F) tom qab straightening. Cov khoom tsis tuaj yeem raug kev ntxhov siab tom qab txias rotary straightening tsuas yog los ntawm kev pom zoo ntawm tus neeg yuav khoom thiab cov chaw tsim khoom.
