API 5L X65 Welded Kab Yeeb Nkab

Tsis pub dhau lub api 5l tsev neeg,X65Feem ntau xaiv thaum cov neeg tsim tawm xav tau kev khiav hauj lwm siab dua thiab ntev} Deb Seev kis, tab sis tseem xav tau qib uas tuaj yeem welded thiab teeb tsa zoo rau ntawm qhov chaw. Nws yog dav tau teev tseg rau cov raj hluav taws xob crude thiab offshore export, thaum siab}}}}} puas ntxiv cov khoom tsis tsim nyog thiab cov khoom sib dhos.

Ib zaug x65 yog xaiv, kev txiav txim siab tom ntej yog lubKhoom daim ntawv: ERW / HFW, LSAW / SAWL lossis SSAW / SAMH. Qhov kev xaiv ntawd yog nyob ntawm seb yuav ua li cas txoj kab yuav ua rau- nteg {} nteg- lay}} Cov tshuab sab nraud yuav tsum muaj rau kev pabcuam.

Cov QibX65yog txhais hauvAPI 5L(kaw kom haum nrogISO 3183), tus qauv tseem ceeb rau kev sib khi thiab cov kav dej welded siv hauv kev thauj hluav taws xob rau cov roj thiab roj kev lag luam. Cov kev tsim qauv xws li "x65m" lossis "x65q" muaj kev cuam tshuam ob qho tib si muaj zog thiab tus me nyuam muaj mob:

• X65 (PSL1)- Baseline Kab Yeeb Qeb
• X65m (PSL2)- Thermo - mechchically ua, txhim kho kev nruj
• X65q (PSL2)- quenched thiab tempered rau cov kev pab xav tau heev

Rau cov ntu kev xav tseem ceeb - xws li ib puag ncig rhiab thiabKev Pab Cuam Tshuam Tawmexport cov kab {{{}}} specifications feem ntau hu rauPSL2 X65Vim tias nws yog kev ntsuas meteristry, yuav tsum muaj cov ntaub ntawv sib tw nruj thiab cov ntaub ntawv kom ntxaws ntxiv. Seamless X65 tau tso cai los ntawm tus qauv, tab sis loj- diam thiab ntev} deb npaum li cas pipelines xaiv xaivWelded X 65Txhawm rau sib npaug muaj peev xwm, weld zoo thiab ua haujlwm tus nqi.

Hauv API 5L system,X65sib raug rau ib qho kev txwv tsawg kawg zog zog (smys) ntawm65,000 psi (≈ 450 mpa)Cov. Tus nqi ntawd ncaj qha mus rau hauv lub phab ntsa - tuab thiab siab cov qauv hauv asme B31.4, B31.8 thiab cov cim zoo sib xws.

Cov lus 1 - Cov yam tsawg kawg nkaus cov tshuab kho mob (siv):

Hauv kev tsim cov kev suav, cov smys yog sib npaug los ntawm kev tsim qauv los muab cov hoop pub dawb, thiab qhov no tau teeb tsa qhov siab tshaj plaws.Tus luagMuab cov npoo ntxiv tawm tsam qhov tsis ua tiav thaum sab hauv siab yog sib xyaw ua ke nrog kev khoov, kub nyuab thiab khoom sab nraud.ElongationYog qhov tseem ceeb thaum lub sij hawm tsim kho thiab ua haujlwm, vim tias cov yeeb nkab tau ua li cas, backfilling thiab ntev}}} lub hauv av txav yam tsis muaj kev tawg.

Rau PSL2 X65, Cov ntaub ntawv ua haujlwm feem ntau qhia meejCharpy V - Cov Lus Cuam Tshuam Tsis Yooj YimNtawm qhov kub thiab txias, thiab, rau cov phab ntsa tuab lossis qis {- Cov kab kub,Dwt(Tso {- hnyav kua muag kua muag) los txhawb kev ntsuas kev ntsuas pob txha.

Yuav ncav cuag x65 lub zog yam tsis muaj kev sib tw dhau nyuaj, qib kev ntseeg tau ntawm kev siv tshuaj phob nti ntau dua li cov ntsiab lus zoo heev. Cov pa roj carbon, Manganese thiab Microalloying ntsiab yog kho ua ke kom tau lub zog thiab cov sulphorus thiab cov leej faj yog txwv weld thiab ha ha ha ha ha had ua tau.

Rooj 2 - Muaj pes ntau yam sib xyaw ua ke rau x65 Welded Kab Yeeb Nkab (Qhov tseem ceeb):

Los ntawm kev nthuav dav dav dav:

• Carbon (c)Muab lub zog muaj zog tab sis yuav tsum tau khaws cia ntawm qib uas ua rau muaj sib npaug carbon sib npaug (CE) haum rau kev ua liaj siv teb vuam.
• Manganese (mn)Txhawb ob lub zog thiab qis {- kub nruj.
• Phosphorus (p) thiab Sulphur (s)yog txo nyob rau hauv PSL2 kom txo qis kev coj tus cwj pwm, tshwj xeeb yog ib puag ncig ntawm welds thiab lub haz.
• Niobium, vanadium thiab titanium (NB / V / TI)Hauv cov nyiaj me me kom ua kom cov qoob loo me me thiab pab ua kom tau raws kev ua kom nruj rau cov phiaj xwm xav tau ntau dua.

Rau cov cheeb tsam txias lossis cov kev pabcuam tawm tsam hauv qhov tob lossis qis - qhov kev txwv dej kub, cov phiaj xwm kev ua tiav kom muab cov npoo ntxiv rau kev tswj hwm cov vuam thiab pob txha lov.

Nyob rau hauv project tua, kev sib tham yog tsis txhob paub daws teeb "X65 steel", tab sis hais txogX65 yeeb nkab ua los ntawm ib tus txheej txheem tshwj xeeb, txhua tus nrog nws tus kheej txoj kab uas hla, phab ntsa - tuab muaj peev xwm thiab cov nqi tus nqi.

ERW / HFW (High - zaus welded):

• Tsim los ntawm kub - rolled coil uas yog grit, tsim rau hauv puag ncig thiab welded raws txoj kev ntev.
• Feem ntau rau cov diam me me thiab nruab nrab nrog nruab nrab phab ntsa tuab hauv av pipelines thiab chaw nres tsheb piping.
• Weld Seam Zoo yog soj ntsuam los ntawm online ndt; Rau cov phiaj xwm PSL2, cov ntawv tshaj tawm hauv zos- Weld Kev Kho Tshav Kub hauv Weld thiab Haz tuaj yeem tau teev tseg.

LSAWW / SAWL (Longitudinal pom):

• Tsim los ntawm phaj siv uoe lossis jco ua, taug qab los ntawm sab hauv thiab sab nraud subs.
• Haum rauCov kab mob loj loj thiab cov phab ntsa tuabYuav tsum muaj nyob rau hauv high - heel trump kab thiab ntug dej kev xa khoom tawm.
• Cov kev qhia tshwj xeeb suav nrog - lub cev ect thiab / lossis RT, thiab kev nyuaj siab} kev kho cua sov kho mob ntawm cov ntu hnyav.

SSAW / SMHH (KAUV KAW):

• Tsim los ntawm chev ntawm ib lub siab tawv thiab txoj kev hlub ob tog ntawm cov txheej txheem ntawm cov txheej txheem arc.
• Txaus nyiam nyob qhov twg diameters thiab coil siv yog cov tsav tsheb tseem ceeb.
• Cov kauv Weld Seam yog luam tawm raws nws qhov ntev tag nrho, feem ntau yog los ntawm UT thiab, uas yuav tsum tau, RT.
• API 5L tso cai rau ob qho tib si tsis txaus thiab welded x65, tab sis rau feem ntau he- bay onshore thiab ntug kev pabcuam pipelines,Welded X 65Yog qhov zoo vim tias nws muaj cov diam dua loj dua, pheej siv weld zoo thiab sib tw sau tus nqi.

Cov "PSL1 / PSL2" BADIX ntawm X65 feem ntau yog cuam tshuamKev ntseeg tau thiab muaj kev ntxhov siab, tsis yog lub zog yooj yim. Smys yog tib yam, tab sis PSL2 ntxiv cov txheej txheem tseev kom muaj rau chemistry, toded, ndt thiab cov ntaub ntawv.

Cov Lus 3 - X65 PSL1 VS PSL2 (Yooj Yim):

Hauv kev xyaum, PSL1 feem ntau siv rau qis {{1} {{} Cov kab ke tseem ceeb thiab cov kab ntawv xa tawm ntsig txog kev tawm tsam.

X65 Welded yeeb nkab tuaj yeem raug txiav txim siab nyob rau hauv ib qho chaw seem uas npog cov kev sib sau ua ke, nrog cov phab ntsa ua kom ruaj khov, nrog nias siab sab nraud thiab ruaj khov.

Cov lus 4 - Cov kab nyob ib txwm muaj rau x65 welded kab yeeb (qhia):

RauKev Pab Cuam Tshuam Tawm, specifications specifications tuaj yeem tswj cov ovality thiab cov khoom lag luam nyob sab nraud, puas sab nraud, reel} nteg, reel} nteg) yog qhov hnyav dua li ntawm cov kab muaj nyob rau sab hauv kab. Cov yeeb nkab xaus tuaj yeem muab tau raws litiaj (PE), beveled (yuav)Los yog nrog kev cai machining kom phim ntes cov neeg raug ntes, teb {-}}} conting cov ntsiab lus lossis tshuab txuas tshuab txuas.

Txoj Kev Npaj Zoo rau X65 ib txwm ua ke hydrotesting, NDT thiab kev kuaj xyuas. Rau raj xa khoom tsim rauKev Pab Cuam Tshuam TawmLos yog ze ntawm txoj kev hauv tsev, tib hom kev sim siv, tab sis lawv cov qhab nia thiab kev lees paub yog feem ntau ua kom zoo nkauj.

Rooj 5 - Qhia kev tshuaj xyuas kev ntsuas (nrog rau kev pab cuam ntawm ntug hiav txwv):

* "Cov kev pabcuam ntawm sab ntug ntxiv" Taw Qhia cov phiaj xwm raug -} cov kab tshwj xeeb rau cov kab hauv qab lossis ze cov kab.

Dhau ntawm lub rooj, offshore kev pab cuam feem ntau xav tau kev tswj kom muaj zogSab nraud corrosion thiab tshuab kev tiv thaivPiv txwv li:

• Kev tsim nyog ntawm cov tshuab sab nraud rau hauv cov khoom siv nyob rau thaum lub sij hawm s - nteg lossis reel- nteg.
• Cov txheej txheem txheej txheej sib koom tes sib koom ua ke tau tshaj nrog cov txheej txheem tseem ceeb.
• Qhob qhov hnyav txheej los yog cov tes tsho kom ua tiav ntawm - bech sab ruaj khov.
• Yeem thib peb -} Kev ua tim khawv (BV, DNV, SGS, thiab lwm yam) rau txheej thiab tshuab kev ntsuam xyuas.

API 5L X65 Cov Yeeb Nkab Rau cov haujlwm no tuaj yeem tsim thiab kuaj hauv qab peb-}}}}}} Tus qauv tsim rau cov lej thiab qhov project QA / QC yuav tsum tau ua.

Rau ntau tus neeg ua haujlwm,X65yog cov tswv yim "qib ua haujlwm" qib yuav tsum tau ua tiav dhau ntawm thaj chaw xis nyob ntawm X52 / X60, tab sis txoj haujlwm tseem ceeb tshaj plaws. Cov ntawv thov raug muaj xws li:

• Ntev - qhov deb deb roj roj thiab cov nkev tsheb kis tau
• Offshore cov kab ntawv xa tawm los ntawm cov tsiaj yug tsiaj rau ntawm ntug dej
• Thaj chaw nyob ze av tsaws chaw thiab cov kev sib tw ua ke
• PIV NTSEG HAIV NEEG PIV TXWV PEROPS THIAB HIGH-} Kev Chaw Nres Nkag Siab} Kev Ntsuas Hluav Taws Xob
• Xaiv cov dej ntws thiab cov ntu tawmer uas x65 haum rau lub ntiaj teb kev tsim qauv

Raws li ib qhov project -} Tea cov khoom lag luam,Lub Paj Tij Pos OctalTuaj yeem muab cov API 5L X65 hauv PSL1 thiab PSL2 nrog ERW, LSAWW Kev xaiv rau cov neeg ua haujlwm, thiab muaj peev xwm npaj cov kev xaiv ntawm tus neeg ua haujlwm, thiab muaj peev xwm npaj cov neeg siv lub engineering
