API 5L X70 qib longitudinally submerged arc welded
Khoom Taw Qhia
X70 Lub Zog Muaj Zog Tso cai rau kev kis cov khoom siv siab dua, txhim kho cov khoom siv roj av siab dua, lossis txo cov ntaub ntawv tib yam ntawm tib lub siab, txuag cov ntaub ntawv thiab cov nqi. X70 Qib Pib Kav Muaj Cov Khoom Kub Zoo Tshaj Plaws {} Taug Kev Kub (xws li EQUE}}}} Cov tog kev puas tsuaj), thiab muaj cov khoom siv tau zoo. Tsis tas li ntawd, lawv nthuav tawm qhov zoo corrosion tsis kam; Los ntawm kev ntxiv cov ntsiab xws li Cu, NI, thiab CR, lossis los ntawm kev sib txuas sab nraud ntawm cov av (xws li ua kom muaj kev txhim kho hauv av los ntawm av thiab cov xov xwm thauj.
Cov Khoom Siv Neeg Kho Tshuab
| Kev Kawm Tshwj Xeeb | Yuav tsum muaj (qhov tseem ceeb) | Hais lus |
|---|---|---|
| Paib lub zog | Ntau dua los yog sib npaug rau 483 MPa (70,000 PSI) | Cov tub ntxhais qhia tshwj xeeb, ua kom cov raj xa hluav taws xob siab - bearing muaj peev xwm. |
| Lub zog tensile | Ntau dua los yog sib npaug rau 565 mpa (82,000 psi) | Paub meej lub zog tag nrho ntawm cov raj xa dej. |
| Tos - rau - muaj zog piv | Tsawg dua los yog sib npaug rau 0.93 | Lub siab siab - - Lub zog piv yog cov qauv hluav taws xob, tab sis cov qauv teeb tsa ib qho kev txwv sab saud kom ntseeg tau tias muaj kev nyab xeeb. |
| Elongation | Ntau dua los yog sib npaug rau 20% | Ua kom cov yeeb nkab steel muaj qee yam℃ntawm cov khoom muaj peev xwm yas ntxiv. |
| Kev Cuam Tshuam | Cov cai nruj yuav tsum tau (feem ntau -10℃lossis -20℃lossis qis dua) | Cov tub ntxhais qhia tshwj xeeb, tiv thaiv brittle bacleure ntawm cov raj xa dej thiab muab cov khoom raug ntes ntes ntes sai. |
Qhov loj me thiab cov duab tshuaj xyuas
Yog qhov tseeb Geometric Qhov ntev yog qhov yuav tsum tau ua ua ntej rau kev ua kom muaj kev txhim kho cov raj xa hluav taws xob ua haujlwm thiab kev nyab xeeb kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv lub caij nyoog ntawm kev siv vuam vuam. Cov kev soj ntsuam no siv cov cuab yeej ntsuas ua laser xws li laser ntawm txoj kab uas hla, phab ntsa, thiab qhov ncaj ncees (chreg qhov siab) ntawm lub qhov ntev tag nrho. Kev tswj nruj ntawm cov taub sab nraud thiab ovality ua kom tau qhov tseeb ntawm-}}}} Cov kev sib dhos ntawm kev sib dhos; Qhov kev sib txuam ntawm cov phab ntsa thickness ncaj qha cuam tshuam kev puas siab {{pearing} cov kabmob muaj peev xwm; Thiab cov kab ncaj heev yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua kom zoo nkauj ntawm kev tso pipeline ntov, tshwj xeeb tshaj yog rau cov raj xa xov hlau traversing complex struts. API cov qauv muaj kev nruj heev rau cov qhov loj me no; Ib qho kev sib txawv ntawm cov kev tsim tawm no yuav ua rau tsis lees txais ntawm cov yeeb nkab steel.
