Vim tias Pipeline Failure raug nqi ntau dua li txheej txheej puas yuav
Ib tug liab qab steel yeeb nkab pib corroding lub sij hawm nws kov av los yog dej. Kaum xyoo underground thiab ib txoj kab uas tsis muaj coated tuaj yeem poob cov phab ntsa tuab txaus los ua tsis tiav nyob rau hauv siab - thiab cov kav xa dej tsis ua haujlwm tsuas yog them nyiaj xwb, lawv kaw cov haujlwm thiab ua rau muaj kev tshawb nrhiav kev nyab xeeb. PebFBE (Fusion Bonded Epoxy) coatedLSAWcev steelmuaj los nres lub moos ua ntej nws pib.
Peb siv longitudinally submerged arc welded (LSAW) yeeb nkab - twb yog qhov kev xaiv muaj zog tshaj plaws rau loj - txoj kab uas hla, siab - cov kab siab - thiab khi rau 250-500μm epoxy txheej ncaj qha mus rau cov hlau ntawm qib molecular. Qhov tshwm sim tsis yog ib txoj haujlwm pleev xim. Nws yog cov tshuaj foob uas ua rau cov pa oxygen, noo noo, thiab cov tshuaj lom neeg hauv av tsis tuaj yeem ncav cuag hlau liab qab.
Vim li cas Engineers Specification FBE Over Ordinary Coatings
Feem ntau cov teeb meem corrosion tsis yog los ntawm cov hlau tsis zoo - lawv yog los ntawm cov txheej uas tev, tawg, los yog disbonds ntawm weld seam. FBE txheej daws qhov tsis ua hauj lwm taw tes cov neeg sib tw tsis quav ntsej:
- Molecular bond, tsis yog daim ntawv cog lus:Cov hmoov epoxy yog electrostatically sprayed rau steel preheated rau 180-250 degree, kho rau saum npoo es tsis zaum saum nws. Tsis muaj delamination, tsis muaj cathodic disbondment ntawm hnub so.
- Cathodic tiv thaiv tau tshaj:FBE yog kev lag luam - txheej txheem txheej rau cov raj xa dej uas tseem ua haujlwm cathodic tiv thaiv kab ke - ob qho tib si ua haujlwm ua ke, tsis yog tawm tsam ib leeg.
- Chemical thiab abrasion resistant:Tuav tawm tsam cov av acidic, dej qab ntsev hauv av, thiab cov neeg kho tshuab kev nyuaj siab ntawm backfilling thiab directional drilling.
- Dielectric zog:Ib txheej FBE siv tau zoo tiv taus 1500V + kev kuaj xyuas hnub so, lub ntsiab lus xoom pinholes rau corrosion los siv.
- Dual - txheej thiab 3PE kev xaiv muaj:Rau cov av pob zeb lossis dej hla dej, peb siv 3-txheej polyethylene (3PE) system hla FBE puag rau ntxiv cov cuab yeej cuab tam.
Ua los ntawm LSAW: Cov Yeeb Nkab Lub Cev Ua Lub Hnyav Lifting
Cov txheej tsuas yog qhov tseem ceeb yog tias cov yeeb nkab hauv qab tuaj yeem nqa lub siab. LSAW yeeb nkab yog tsim los ntawm ib lub phaj steel, nias rau hauv U, ces ib qho O, ces welded longitudinally nyob rau hauv submerged arc - ua ib tug ncaj, ntau dimensionally zoo ib yam yeeb nkab dua kauv -welded (SSAW) lwm txoj nyob rau tib txoj kab uas hla. Yog vim li cas LSAW dominates nyob rau hauv:
| Specification | Paub meej |
|---|---|
| Txuj | API 5L, ISO 3183, GB/T 9711 |
| Qib | X42–X80, B, PSL1/PSL2 |
| Sab nraud | 406mm-1420mm (16 "-56") |
| Phab ntsa Thickness | 6mm-40mm |
| Txheej Thickness | 250–500μm ib zaug - txheej FBE; 3PE mus txog 3.0mm tag nrho |
| Ntev | 6m, 12m, lossis ib qhov project kos duab |
| Xaus | Beveled, tiaj, lossis ib tus neeg siv khoom spec |
Qhov Pipe no mus ua hauj lwm
- Ntev -cov roj & roj kis kab- qhov twg txheej tsis ua hauj lwm txhais tau hais tias muaj ntau -kilometer excavation
- Lub nroog dej thiab dej khib nyiab infrastructure- qhov twg av corrosivity yog unpredictable thiab kev pab cuam lub neej yog ntsuas nyob rau hauv kaum xyoo
- Offshore pipeline shore ze ze- qhov twg FBE ua cov txheej txheem hauv qab hnyav dua 3PE lossis 3PP systems
- Industrial txheej txheem kav- chemical nroj tsuag, refineries, thiab desalination kab nqa corrosive media
FAQ
Q: Dab tsi yog qhov txawv ntawm FBE thiab 3PE txheej rau cov yeeb nkab steel?
A: FBE yog ib qho kev sib xyaw ua ke -cov txheej txheem epoxy muab cov tshuaj adhesion muaj zog thiab cathodic tiv thaiv kev sib raug zoo. 3PE ntxiv cov nplaum nplaum thiab polyethylene topcoat hla FBE puag, muab cov khoom siv ntxiv thiab kev tiv thaiv kev tiv thaiv - feem ntau teev rau pob zeb trenches lossis siab dua txhua yam kev teeb tsa {{3}.
Q: FBE coated LSAW yeeb nkab puas tuaj yeem ua teb -welded yam tsis ua rau cov txheej?
A: Yog. Cov txheej txheem kev xyaum tawm ib cheeb tsam liab qab (feem ntau 100–150mm) ntawm txhua cov yeeb nkab kawg rau girth welding, uas yog tom qab ntawd teb-coated nrog tshav kub-shrink tes tsho los yog kua epoxy thaj tshuab kom rov qab tau tag nrho.
Q: Dab tsi yog qhov kev pab cuam lub neej ntawm FBE coated pipeline?
A: Kev siv FBE txheej zoo ua ke nrog kev tiv thaiv cathodic feem ntau xa 30+ xyoo ntawm kev tiv thaiv corrosion nyob rau hauv faus thiab submerged kev pab cuam, uas yog vim li cas nws tseem yog lub neej ntawd kev xaiv rau loj kis pipelines thoob ntiaj teb.
Q: Koj puas muab LSAW yeeb nkab tsis muaj txheej, rau cov neeg siv khoom siv lawv tus kheej?
A: Yog - Bare LSAW yeeb nkab rau API 5L muaj, nrog rau txheej txheej - tsuas yog cov kev pabcuam yog tias koj muab koj tus kheej cov yeeb nkab.
