Yam khoom no yog dab tsi
IbFBE coated LSAW yeeb nkabyog qhov loj - txoj kab uas hla, longitudinally welded steel yeeb nkab - tsim los ntawm dov phaj thiab koom nrog submerged arc vuam - uas muaj ib txheej sab nraud (thiab qee zaum sab hauv) txheej ntawm fusion bonded epoxy thov ntawm lub zeb ua ntej khoom xa tuaj. Cov hlau thiab cov txheej yog ob qhov kev tsim khoom sib cais tsim nyog raws li ob qho kev sib cais ntawm cov qauv, thiab cov neeg yuav khoom ntsuas qhov kev tsocai yuav tsum tau kho lawv txoj kev ntawd es tsis yog ib qho khoom tshwj xeeb.
Qhov twg cov khoom no feem ntau tshwm sim hauv ib qhov project:
- Hla -cov roj thiab roj hauv lub tebchaws
- Cov kav dej siv lub cev
- Sib sau cov kab thiab flowlines ntawm qhov chaw tsim khoom
- Raws li cov txheej txheem primer hauv qab 3LPE lossis 3LPP lub tsho sab nrauv ntawm ntau qhov xav tau
Yuav ua li cas cov txheej tiag tau siv
Qhov no yog feem ntau cov nplooj ntawv cov khoom hla dhau, tab sis nws tseem ceeb rau kev ntsuam xyuas cov khoom lag luam zoo:
- Cov yeeb nkab yog abrasive moj tej tawg huv si (feem ntau yog Sa 2.5) kom tshem tawm cov nplai zeb, xeb, thiab roj, thiab tsim kom muaj ib qho kev ntxhib los mos.
- Cov yeeb nkab yog induction-rhuab mus rau lub hom phiaj ntau yam, feem ntau qhov chaw ntawm 200℃thiab 250℃nyob ntawm cov hmoov txheej.
- Epoxy hmoov yog txau electrostatically rau ntawm cov yeeb nkab kub, qhov twg nws melts ntawm kev sib cuag.
- Cov zaj duab xis molten ntws mus rau hauv lub moj tej tawg profile thiab pib hla -txuas (kho) yuav luag tam sim ntawd thaum cov yeeb nkab txias.
- Cov yeeb nkab coated yog dej-quenched, thiab cov txheej yuav raug kuaj xyuas qhov tuab, hnub so (pinholes), thiab adhesion ua ntej tso tawm.
Vim tias cov tshuaj tiv thaiv kho tau tshwm sim ntawm kev sib cuag nrog cov hlau kub, FBE tsis tuaj yeem siv qhov tseeb hauv qhov chaw ua kua txheej txheej tau - qhov no yog lub khw- siv txheej, thiab cov yeeb nkab kawg yog ib txwm tso liab qab rau qhov kev ncua deb kom tso cai rau girth welding ntawm qhov chaw.
Cov ntawv sau ua haujlwm (nrog rau qhov twg nws tsis yog qhov kev xaiv zoo tshaj)
FBE lub zog tseem ceeb yog adhesion: vim hais tias zaj duab xis yog chemically bonded es tsis yog mechanically daig rau saum npoo, nws tuav tau zoo nyob rau hauv cathodic tiv thaiv nyob rau lub sij hawm ntev kev pab cuam, thiab nws tsis nyiam disbond txoj kev ib co kab xev los yog thee -tar systems ua tau.
Qhov twg nws tsis muaj zog: ib txheej FBE tsuas muaj kev tiv thaiv tsis zoo rau gouging thiab cuam tshuam piv rau 3LPE. Ntawm pob zeb backfill, kab rov tav directional drilling rub seem, los yog txoj kev / dej hla qhov twg cov yeeb nkab tau rub los yog ntaus thaum lub sij hawm installation, ib leeg -txheej FBE feem ntau tsis yog txoj cai spec ntawm nws tus kheej - ob qho tib si - txheej abrasion- tiv thaiv FBE system los yog tag nrho 3{ PE / PP system. Tus neeg muag khoom uas pom zoo ib txheej FBE rau txhua qhov teeb meem kev teeb tsa yam tsis tau nug txog kev rov qab ua dua thiab kev teeb tsa yog hla ib kauj ruam uas tseem ceeb.
Cov Qauv: Yeeb Nkab vs. Txheej (Tsis txhob Confuse Cov no)
| Tswj | Hom qauv |

| Txheej zaj duab xis thickness (typical) | 300-600 microns, ib txheej |
| Cov qib hlau feem ntau ua ke nrog FBE | API 5L Qib B txog X80 |
| OD ntau yam (LSAW) | 406.4 hli-1,626 hli (16 "-64") |
| Nto prep qib | Sa 2.5 nyob ze -White blast |
Daim ntawv pov thawj zeb xeem uas tsuas yog hais txog cov qauv yeeb nkab, yam tsis muaj daim ntawv tshuaj ntsuam xyuas txheej txheem (thickness readings, holiday test results, adhesion test), tsis tiav rau FBE-coated khoom.
Kev Qhia Txog Kev Yuav Khoom: Yuav Ua Li Cas Ua Ntej Ua Ntej Order
Xaiv txoj cai FBE LSAW yeeb nkab yuav tsum muaj ntau tshaj qhov kev lees paub txoj kab uas hla thiab phab ntsa tuab. Cov neeg yuav khoom yuav tsum tshuaj xyuas cov ntsiab lus hauv qab no nrog lawv tus neeg muag khoom:
- Paub meej cov txheej txheem txheej, tsis yog "FBE."Cov qauv sib txawv (ISO 21809-2, CSA Z245.20, AWWA C213) qhia cov txheej txheem sib txawv ntawm qhov kev npaj, tuab, thiab hnub so (pinhole) kev xeem cov cai. Nug tus neeg muag khoom uas tus txheej txheem txheej txheej tsim nyog thiab raug sim rau.
- Txheeb xyuas qib kev npaj nto.Sa 2.5 moj tej tawg tu yog tus qauv rau FBE daim ntawv thov; blasting tsis txaus yog ib qho ntawm feem ntau ua rau cov txheej txheem ntxov ntxov. Thov mills cov ntaub ntawv qhia txog qhov profile thiab kev huv huv.
- Tshawb xyuas txheej tuab thiab cov ntaub ntawv kuaj xyuas hnub so.Thov kev tshawb nrhiav hnub so (kev sim ntsuas hluav taws xob) cov lus ceeb toom rau txhua qhov sib koom ua ke, nrog rau cov ntaub ntawv ntsuas tuab ntawm ntau lub ntsiab lus nyob ib puag ncig.
- Match qib steel rau cov kev pabcuam.Rau kev siv cov kav dej, qib steel (piv txwv li, X60, X70) yuav tsum raug xaiv raws li kev tsim siab, tsis yog qib siab tshaj plaws muaj - tshaj -qhia txog qib nce nqi yam tsis muaj txiaj ntsig zoo rau qis dua - kev pabcuam siab.
- Nug txog girth weld txheej compatibility.Txij li thaum FBE tsis tuaj yeem ua ntej- siv rau thaj tsam ntawm thaj chaw weld, paub meej tias cov yeeb nkab kawg puas yog sab laug liab qab rau thaj tsam sib koom ua ke thiab qhov liab qab li cas - qhov kawg ntev uas tus neeg muag khoom muab.
- Thov thib peb -txoj kev tshuaj ntsuam xyuas.Rau kev txiav txim loj, thib peb-kev tshuaj ntsuam xyuas (SGS, BV, TÜV, lossis zoo sib xws) ntawm ob lub hauv paus yeeb nkab vuam (ib API 5L / ISO 3183) thiab daim ntawv thov txheej (raws li txheej txheem txheej txheej) yog cov qauv kev coj ua rau cov neeg yuav khoom.
- Paub meej txog kev thauj khoom thiab kev tuav pov hwm.FBE txheej tuaj yeem raug puas tsuaj los ntawm kev sib tsoo tsis raug, saw slings, lossis UV raug thaum lub sij hawm ntev cia sab nraum zoov. Nug seb kev tiv thaiv dab tsi (padded cradles, coating fix kits) suav nrog.
- Qhia kom meej cov txheej txheem kho.Kev puas tsuaj me me thaum tuav yog muaj; nug seb tus neeg muag khoom puas muab FBE thaj / kho cov ntaub ntawv thiab seb cov txheej txheem kho puas tau sau tseg raws li kev tswj hwm txheej txheem.
FAQ
Q: Puas yog FBE tib yam li cov xim epoxy?
A: Tsis yog. Epoxy xim yog kua, hnyav- lossis dej-raws li txheej siv los ntawm txhuam lossis tshuaj tsuag thiab cua- lossis cua sov- kho. FBE yog cov hmoov hmoov uas yog electrostatically sprayed rau steel rhuab zoo saum cov hmoov melt point, yog li cov ntaub ntawv los ntawm fusion es tsis yog los ntawm hnyav evaporation. Ob leeg muaj qhov sib txawv adhesion mechanisms thiab tsis hloov rau ib leeg hauv cov kav dej spec.
Q: Vim li cas thiaj tso cov yeeb nkab xaus tsis muaj coated?
A: Girth welding nyob rau hauv daim teb yuav tsum liab qab hlau. Yog tias FBE npog tag nrho cov yeeb nkab ntev, qhov chaw vuam yuav xav tau cov txheej txheem ua ntej vuam, thiab cov cua sov los ntawm vuam yuav ua rau cov txheej uas nyob ib sab tsis hais. Tawm ntawm qhov liab qab- qhov kawg nyiaj pub dawb (ntev sib txawv ntawm qhov project spec) yog qhov yooj yim dua thiab zoo ib yam dua li daim teb - stripping.
Q: Yuav ua li cas tus neeg yuav khoom paub tias cov txheej txheem yuav kav ntev, tsis yog qhov zoo ntawm kev xa khoom?
A: Tsis muaj cov txheej txheem txheej txheem tuaj yeem lav qhov kev ua haujlwm ntawm kev ua haujlwm tsis muaj kev teeb tsa zoo - uas yog qhov kev txwv ncaj ncees, tsis yog evasiveness. Qhov koj tuaj yeem txheeb xyuas ua ntej xa khoom yog qib kev npaj ua ntej, kho lub xeev (ntawm cov kuab tshuaj rub lossis DSC kuaj yog tias tau teev tseg), tuab, thiab hnub so - pub dawb txuas ntxiv. Ntev- kev ua tau zoo tom qab ntawd nyob ntawm qhov hnyav ntawm kev tuav thaum thauj / stringing thiab ntawm cathodic tiv thaiv kab ke raug txib kom raug tom qab faus.
Q: Lub neej kev pab cuam ntawm FBE -coated LSAW yeeb nkab yog dab tsi?
A: Kev pabcuam lub neej yog nyob ntawm qhov zoo ntawm kev teeb tsa, cov av hauv av, thiab seb puas muaj kev tiv thaiv cathodic kom raug, yog li cov neeg muag khoom feem ntau tsis hais txog pes tsawg xyoo. Kev thov kom raug thiab teeb tsa FBE txheej, ua ke nrog kev tiv thaiv cathodic, yog tsim los txhawb kev tsim cov raj xa dej uas feem ntau tau teev tseg hauv 20-50 xyoo hauv kev ua lag luam, tab sis qhov no yuav tsum tau soj ntsuam ntawm ib qhov project- tshwj xeeb hauv paus.
