Yog vim li casLSAW steel yeeb nkabQhov tseem ceeb rau Kev Tsim Kho Chaw Nres Nkoj thiab Chaw Ua Lag Luam?
Cov chaw nres nkoj niaj hnub thiab cov chaw tsim khoom hnyav yuav tsum muaj cov khoom siv uas muaj peev xwm txhawb nqa cov khoom loj thaum tuav lub sijhawm ntev - kev ntseeg siab hauv qhov xav tau ib puag ncig. Txawm hais tias tsim kev sib sib zog nqus- dej dav hlau, cov nroj tsuag petrochemical, chaw txais LNG, chaw nres tsheb sab nrauv, lossis cov chaw tsim khoom loj, cov kws ua haujlwm yuav tsum xaiv cov khoom siv hlau uas muaj zog, qhov tseeb qhov tseeb, thiab ua haujlwm ntev.
Longitudinal Submerged Arc Welded (LSAW) steel yeeb nkab tau dhau los ua ib qho ntawm cov khoom siv zoo tshaj plaws rau cov haujlwm no vim tias nws muab cov cuab yeej tsim khoom siab heev nrog kev ua haujlwm tshwj xeeb. Tsim los ntawm siab - zoo steel daim hlau los ntawm JCOE los yog Yob Bending Expansion (RBE) tsim, ua raws li ob chav submerged arc vuam, LSAW steel yeeb nkab muaj superior weld kev ncaj ncees thiab ruaj khov kev ua tau zoo.
Tsis zoo li cov pa welded yeeb nkab, LSAW steel yeeb nkab tuaj yeem tsim nyob rau hauv loj diameters thiab hnyav phab ntsa thicknesses thaum tuav zoo heev roundness thiab meej qhov ntev kam rau ua. Cov txiaj ntsig zoo no ua rau nws tsim nyog tsis yog rau kev thauj mus los ntawm cov kua dej xwb tab sis kuj rau cov qauv tsim, cov yeeb nkab steel, cov chaw nres nkoj hauv hiav txwv, kev cob qhia kev lag luam, cov tshuab ntim khoom, thiab kev tsim vaj tsev hnyav.
Niaj hnub no, LSAW steel yeeb nkab tau dav tsim raws li API 5L, GB / T 9711, ASTM, thiab EN cov qauv, tso cai rau nws ua tau raws li cov kev cai ntawm cov kev tsim vaj tsev loj thoob plaws ntiaj teb.

Yuav ua li cas LSAW Steel Yeeb Nkab Txhim Kho Cov Txheej Txheem Kev Ruaj Ntseg Hauv Kev Lag Luam hnyav?
Cov chaw ua haujlwm hnyav feem ntau ua haujlwm nyob rau hauv cov xwm txheej uas muaj cov khoom siv loj, kev vibration, kub hloov pauv, thiab kev tsim khoom tas mus li. Cov ntaub ntawv tsim qauv yuav tsum yog li ntawd muab sijhawm ntev - lub sijhawm ruaj khov thaum tswj xyuas kev ua haujlwm zoo ib yam nyob rau ntau xyoo ntawm kev ua haujlwm.
Lub peev xwm muaj peev xwm muaj peev xwm txhawb nqa loj Engineering Structures
Ib qho ntawm qhov zoo tshaj plaws ntawm LSAW steel yeeb nkab yog nws cov khoom zoo heev -cov kabmob muaj peev xwm. Ua los ntawm cov hlau hnyav nrog qib siab - lub zog steel, LSAW yeeb nkab muaj qhov ua tau zoo heev rau kev khoov, compression, thiab kev thauj khoom sab nraud.
Rau kev tsim kho chaw nres nkoj, LSAW steel yeeb nkab feem ntau yog siv los ua steel yeeb nkab pawg txhawb nqa wharves, thawv terminals, offshore platforms, choj foundations, thiab marine lug.Txoj kab uas hla loj tso cai rau lub hauv paus muaj peev xwm ntau dua thaum txo cov pawg uas xav tau thaum tsim kho.
Hauv kev lag luam cov nroj tsuag, LSAW steel yeeb nkab tau dav siv rau cov kav dej siv hluav taws xob, cov kab ke, cov khoom siv hauv paus, cov txheej txheem kav dej, thiab siab - cov tshuab xa hluav taws xob siab uas ob qho tib si kev ntseeg tau thiab qhov ntsuas qhov tseeb yog qhov tseem ceeb.
Advanced Manufacturing kom ntseeg tau tias kev ua tau zoo ntawm cov qauv
Cov txheej txheem tsim khoom pib nrog precision ntug milling ua ntej steel daim hlau tsim siv JCOE lossis RBE thev naus laus zis. Ob chav submerged arc vuam tom qab ntawd ua tiav ob qho tib si sab hauv thiab sab nraud weld seams raws li kev tswj xyuas zoo.
Tom qab welding, ntau cov kab ntau lawm ua cov cuab yeej nthuav dav los txhim kho kev sib tw thaum txo qis kev ntxhov siab. Cov txheej txheem no txhim kho qhov sib xws thiab txhim kho cov txheej txheem kev ua haujlwm ntawm cov khoom tiav.
Kev soj ntsuam zoo kom txo qis kev pheej hmoo ntawm kev tsim kho
Txhua LSAW steel yeeb nkab feem ntau dhau mus kuaj ultrasonic, kuaj hluav taws xob, kuaj hydrostatic siab, ntsuas qhov ntev, thiab kuaj pom ua ntej xa khoom. Cov txheej txheem tswj kev ua tau zoo no ua kom ua tau raws li cov qauv thoob ntiaj teb thaum txo qis qhov tshwm sim ntawm qhov tsis xws luag thaum lub sijhawm teeb tsa.
Vim li cas Corrosion Resistance thiab Lub Neej Ua Haujlwm Ntev Tseem Ceeb?
Cov chaw nres nkoj thiab cov dej hiav txwv muaj kev lag luam txuas ntxiv raug rau cov dej hiav txwv, tshuaj tsuag ntsev, av noo, thiab hloov pauv kub. Cov cheeb tsam nruj no tuaj yeem ua rau muaj kev txhim kho corrosion yog tias cov ntaub ntawv tsis muaj kev tiv thaiv zoo.
Txhawm rau txhim kho lub sijhawm ntev ntev, LSAW steel kav feem ntau muab nrog cov txheej txheem sab nraud xws li Fusion Bonded Epoxy (FBE), Peb- Txheej Polyethylene (3PE), thiab Peb- Txheej Polypropylene (3PP). Sab hauv epoxy txheej kuj tseem raug teev tseg rau cov kav dej thauj cov dej, tshuaj, lossis lwm yam xov xwm corrosive.
Cov txheej txheem tiv thaiv no txuas ntxiv lub neej kev pab cuam thaum txo kev saib xyuas zaus thiab cov nqi khiav haujlwm. Ua ke nrog siab -kev tsim khoom zoo thiab cov txheej txheem tshuaj xyuas nruj, kev tiv thaiv corrosion ua rau LSAW steel yeeb nkab kom muaj kev ntseeg tau zoo thoob plaws tag nrho lub neej tsim ntawm cov chaw tsim khoom.
Yuav Ua Li Cas International Standards Support Engineering Quality?
Cov haujlwm loj engineering xav tau cov khoom lag luam uas ua raws li cov qauv kev paub thoob ntiaj teb. API 5L thiab GB / T 9711 tsim cov kev cai dav dav uas suav nrog cov khoom siv raw zoo, cov txheej txheem vuam, cov khoom siv kho tshuab, kuaj hydrostatic, qhov ntev ntev, thiab tsis yog - kuaj xyuas puas.
Ua raws li cov qauv no kom ntseeg tau tias txhua LSAW steel yeeb nkab ua tau raws li qhov xav tau ntawm engineering specifications thaum muab cov khoom zoo sib xws thoob plaws ntau qhov ntau lawm. Cov neeg tsim khoom nrog cov chaw tsim khoom sib xyaw ua ke tuaj yeem txhim kho cov khoom lag luam kev ntseeg siab ntxiv los ntawm kev tswj cov txheej txheem nruj thiab kev tshuaj ntsuam xyuas thoob plaws txhua theem ntawm kev tsim khoom.
Rau cov tswv hauv vaj tse, qhov kev tsim khoom sib xws no txo cov kev pheej hmoo ntawm kev tsim kho thaum txhim kho lub sijhawm ntev - kev nyab xeeb kev ua haujlwm.
Txoj Haujlwm Reference: CNOOC Terminal Project
Ib qho piv txwv ntawm LSAW steel yeeb nkab siv hauv marine infrastructure yog qhovCNOOC Terminal Project, qhov twg Huayang Steel Pipe muab kwv yees li3,000 tons ntawm LSAW steel yeeb nkab tsim nyob rau hauvL360Mqib nrog ib tug specification ntawm914 × 12 hli.
Qhov project xav tau loj - txoj kab uas hla steel kav uas muaj peev xwm los txhawb nqa cov qauv hnyav thaum tswj xyuas cov khoom siv kho tshuab txhim khu kev qha hauv ib puag ncig ntug hiav txwv. Los ntawm kev tsim cov thev naus laus zis, muab ob npaug rau submerged arc vuam, nruj tsis yog -kev kuaj kev puas tsuaj, thiab kev tswj hwm zoo, cov khoom siv tau ua tiav txaus siab rau qhov project cov kev qhia tshwj xeeb thiab kev tsim kho.
Daim ntawv thov kev vam meej no qhia tau hais tias yuav ua li cas LSAW steel yeeb nkab ua ke nrog cov qauv tsim muaj zog, qhov tseeb qhov tseeb, thiab kev vam khom vuam zoo los txhawb kev tsim kho chaw nres nkoj niaj hnub thiab kev lag luam hnyav.
