Dab tsi PSL2 Tiag Ntxiv Tshaj PSL1
PSL1 teeb tsa cov cuab yeej cuab tam yam tsawg kawg nkaus thiab tawm qhov kev sim feem ntau rau tus neeg yuav khoom qhov kev txiav txim siab. PSL2 hloov pauv uas nyob rau hauv ntau txoj kev tshwj xeeb, kuaj tau:
- Tighter thiab bounded chemistry.PSL2 txwv tsis pub qis carbon sib npaug (CE) ntau dua li PSL1 rau tib qib, uas yog qhov ua rau PSL2 yeeb nkab nws qhov kev kwv yees, qis -preheat field weldability.
- Ib lub yield zog qab nthab, tsis yog hauv pem teb.PSL1 tsuas yog teeb tsa lub zog tsawg kawg nkaus. PSL2 teeb tsa qhov tsawg kawg nkaus thiab qhov siab tshaj plaws. Qhov kev khi sab saud yog qhov tseem ceeb rau kev lim-raws li kev tsim cov raj xa dej, qhov twg ntau tshaj - lub zog yeeb nkab lub cev tuaj yeem hloov pauv qhov sib sib zog nqus weld coj li cas hauv kev khoov.
- Yuav tsum tau kuaj Charpy V-notch (CVN) cuam tshuam.PSL1 tsis tas yuav muaj kev cuam tshuam kev sim txhua. Raws li PSL2, txhua lub yeeb nkab raug sim rau qhov tawv, uas yog cov cuab yeej txiav txim siab seb puas muaj qhov tsis xws luag tuaj yeem ua rau qeeb, muaj kua muag los yog ceev ceev - khiav nkig tawg.
- Yuav tsum tau ua, puv -ntev NDT.PSL1 tawm tsis yog- kev sim ua kom puas tsuaj loj heev kom pom zoo. PSL2 xav kom tag nrho ntev ntawm txhua cov yeeb nkab yuav raug tshuaj xyuas, tsis muaj kev hloov pauv ntawm cov qauv rau kev pov hwm.
- Yuav tsum tau kuaj hydrostatic ntawm txhua cov yeeb nkab, uas tsis muaj lwm txoj kev txais nyob rau hauv qhov chaw ntawm nws.
Tsis muaj qhov no xaiv tau thaum PSL2 tau teev tseg - nws yog lub ntsiab lus ntawm PSL2, tsis yog pob khoom hloov kho rau saum nws.
Vim li cas LSAW Cov Neeg Yuav Khoom Yuav Tsum Tau Nyeem Cov Seam Requirements tshwj xeeb
Ntawm seamless yeeb nkab, PSL2 toughness kuaj yog lub hauv paus- lus nug hlau. Ntawm LSAW yeeb nkab, nws tsis yog - vuam seam thiab tshav kub- thaj chaw cuam tshuam (HAZ) yog cov chaw sib cais uas nqa lawv tus kheej toughness thiab soundness yuav tsum tau:
- CVN kev ntsuam xyuas ntawm welded PSL2 yeeb nkab yog muab los ntawm cov hlau vuam thiab HAZ, ntxiv rau cov hlau hauv paus, vim hais tias cov seam yog qhov chaw ntawm cov kav dej tsis zoo yog qhov tseeb feem ntau yuav tshwm sim.
- 100% NDT kev pab them nqi ntawm LSAW yeeb nkab txhais tau hais tias ob leeg niam txiv phaj thiab ua tiav ob chav submerged arc weld raug tshuaj xyuas raws lawv qhov ntev, feem ntau los ntawm kev ntsuas ultrasonic automated supplemented los ntawm radiography ntawm phaj kawg thiab seam pib / nres cov ntsiab lus.
- Rau cov qib siab dua thiab txoj kab uas hla loj dua, poob- qhov hnyav dua qhov ntsuas (DWTT) feem ntau ntxiv rau saum CVN kom paub meej tias cov yeeb nkab lub cev tiv thaiv kev sib tsoo, tsis yog ib qho - taw tes cuam tshuam.
- Kev cob qhia khoov kev kuaj ntawm cov qauv weld paub meej tias cov seam muaj qhov txaus ductility, cais los ntawm thiab ntxiv rau nws qhov kev ntsuas toughness.
Ib lub zeb quoting PSL2 LSAW yeeb nkab tsis muaj seam meej-thiab-HAZ kev sim kev npaj yog hais cov ntaub ntawv qib PSL1- nyob rau hauv daim ntawv lo PSL2 - qhov sib txawv uas tsuas yog tshwm sim thaum thov cov ntaub ntawv xeem tiag tiag.
Sour Service thiab Offshore: PSL2 yog pem teb, tsis yog tag nrho cov lus teb
PSL2 yog qhov yuav tsum tau ua ua ntej rau ob txoj haujlwm sib xws- qib yuav tsum tau ua, tab sis nws tsis tuaj yeem suav nrog ib qho:
- Kev pabcuam qaub (NACE MR0175 / ISO 15156).Cov yeeb nkab npaj rau H2S- muaj cov kev pabcuam xav tau cov kua qaub- pabcuam ntxiv rau qhov kev xaiv qib (piv txwv li, X60QS lossis X65NS), uas ua rau muaj cov tshuaj lom neeg ntxiv, hardness, thiab cua sov- tswj kev kho mob dhau qhov kev xav tau ntawm PSL2. Kev txiav txim siab PSL2 X60 tsis xa cov qaub{10}}kev pabcuam- cov yeeb nkab ntsuas.
- Offshore Service (Annex J).Subsea thiab offshore installation ntxiv nws tus kheej txheej ntawm kev sib tsoo tsis kam, qaug zog, thiab kev teeb tsa- thauj khoom tsim nyog nyob rau sab saum toj ntawm PSL2 lub hauv paus.
Ob qhov txuas ntxiv raug hu tawm cais ntawm daim ntawv xaj xaj thiab txheeb xyuas nrog lawv tus kheej daim ntawv pov thawj - PSL2 tau txais ib txoj haujlwm feem ntau ntawm txoj kev yuav tsum tau ua, tab sis nws tsis yog qhov hloov pauv rau npe rau cov ntawv txuas ntxiv kom meej.
Ib Case Tsim Nyog Paub
Ib tus neeg cog lus tau xaj API 5L X65 PSL2 LSAW yeeb nkab rau qhov project nyob rau hauv ib cheeb tsam txias - huab cua, raug hais txog PSL2 rau qhov yuav tsum tau kuaj qhov cuam tshuam. Qhov kev txiav txim yuav tsis tau qhia meej yog CVN qhov ntsuas kub thiab cov qauv kev taw qhia. Lub zeb, ua hauj lwm los ntawm lub hauv paus API 5L yuav tsum tau, sim thiab ntawv pov thawj ntawm tus qauv siv kub thiab orientation - technically ua raws li PSL2, tab sis luv luv ntawm qhov ntsuas kub thiab transverse orientation project tus tsim code tiag tiag xav tau rau qhov kev nyab xeeb. Qhov tsis sib haum xeeb tshwm sim thaum kev tshuaj xyuas cov ntaub ntawv, tsis yog thaum lub sijhawm tsim khoom, tab sis nws tseem txhais tau tias rov- kuaj cov qauv khaws cia thiab ncua sijhawm xa khoom. PSL2 teeb tsa qhov kev sim tsawg kawg nkaus; qhov project-qhov tshwj xeeb kub, kev taw qhia, thiab qhov kev lees paub tseem yuav tsum tau sau rau hauv qhov kev txiav txim.
Nyeem daim ntawv qhia tseeb PSL2 Mill Test
PSL2 MTR uas txhawb nqa cov yeeb nkab yuav tsum pom, yam tsawg kawg nkaus:
- Thaum tshav kub kub thiab yeeb nkab traceability txuas chemistry, mechanical test results, and NDT records to the particular length of pipe.
- Muab xam cov pa roj carbon sib npaug nrog rau raw chemistry, tsis yog daim ntawv hla / tsis ua haujlwm
- CVN joule qhov tseem ceeb nrog kev ntsuas kub thiab cov qauv kev taw qhia tau teev tseg, rau lub hauv paus hlau, vuam, thiab HAZ ntawm cov khoom welded
- Ib txoj kev NDT tau teev tseg thiab kev pab them nqi (ultrasonic, radiographic, lossis ob qho tib si) lees paub tag nrho -ntev soj ntsuam, tsis pom qhov ntsuas
- Hydrostatic xeem siab thiab tuav lub sij hawm kaw rau ib lub yeeb nkab
Yog hais tias ib qho ntawm cov no ploj lawm los yog sau ua ib qho liab qab "PASS," nws tsim nyog nug lub zeb rau cov ntaub ntawv hauv qab ua ntej cov yeeb nkab nkoj, tsis yog tom qab nws tuaj txog ntawm qhov chaw.
FAQ
Q: Puas yog PSL2 tau txiav txim siab tias cov yeeb nkab haum rau kev pabcuam qaub lossis kev pabcuam sab nraud?
A: Tsis yog. PSL2 yog lub hauv paus zoo tier cov kev pabcuam tsim los ntawm, tab sis kev pabcuam qaub (NACE MR0175 / ISO 15156, nrog rau qib NS / QS / MS) thiab kev tsim nyog ntawm ntug dej hiav txwv (Annex J) yog cais cov cai uas yuav tsum tau muab npe rau ntawm qhov kev txiav txim.
Q: Puas yog CVN kuaj tau ua tiav ntawm qhov vuam seam rau LSAW yeeb nkab, lossis tsuas yog lub hauv paus phaj?
A: Ob leeg. PSL2 welded yeeb nkab yuav tsum muaj kev ntsuam xyuas ntawm cov hlau vuam thiab cua sov- cuam tshuam cheeb tsam ntxiv rau cov hlau hauv paus, vim tias cov seam yog qhov chaw feem ntau yuav tswj tau qhov kev ua tau zoo ntawm cov khoom siv welded.
Q: PSL1 yeeb nkab puas tuaj yeem rov- ntawv pov thawj rau PSL2 tom qab nws tau tsim lawm?
A: Feem ntau tsis muaj. PSL2 yuav tsum tau ua rau hauv kev tsim khoom, kev sim, thiab cov ntaub ntawv txheej txheem txij thaum pib; cov yeeb nkab twb tau ntawv pov thawj nkaus xwb rau PSL1 yuav tsum tsis txhob sawv cev li PSL2 yam tsis muaj cov ntaub ntawv tsim khoom qub thiab kev sim siab txhawb nqa nws.
Q: Qhov ntsuas kub thiab kev taw qhia dab tsi kuv yuav tsum qhia rau CVN kuaj?
A: API 5L teeb tsa lub neej ntawd, tab sis qhov ntsuas kub thiab kev taw qhia qhov tseem ceeb rau koj lub raj xa dej yog nyob ntawm tus qauv tsim qauv, qhov ntsuas qhov tsawg kawg nkaus, thiab qhov project specification - lees paub qhov no nrog koj tus kws tsim qauv tsim thiab muab tus nqi tseeb ntawm kev yuav khoom es tsis tso siab rau tus qauv lub neej ntawd.
