1. Tus qauv 1163 tus qauv
Tus txheej txheem tag nrho yogRaws li 1163: {2016 - Cov qauv hlau hollow cov ntuCov. Nws npog peb hom welded kav dej:
CHS (Vas Hollow ntu ntu): Kav dej.
Shs (square hollow ntu ntu): Box tshooj nrog sib npaug sab.
RHS (duab plaub Hollow tshooj): Box tshooj nrog cov khoom sib xws.
Tus qauv txhais tau tias yuav tsum muaj rau:
Cov cim hlau:Cov cuab yeej kho tshuab (tawm los lub zog, tensile lub zog).
Qhov loj me thiab kev ua kom ntev:Sab nraum txoj kab uas hla (OD), Phab Ntsa Thickness (WT), thiab ntev.
Kuaj:Tshuaj lom neeg cov tshuaj lom neeg, kev ntsuam xyuas txhua yam (tensile, flattening, flaring), thiab tsis yog - kev sim siab ntawm Weld.
2. LSAWW Cov Txheej Txheem Tsim (JBOe Txoj Kev)
Cov txheej txheem feem ntau rau kev tsim ua 1163 lsaw kav yog tusJcoe Txheej Txheem:
Kev npaj phaj:Cov phiaj hlau ua raws li Australian cov qauv (piv txwv li, AS / NZS 3678) raug txiav rau qhov dav dav thiab ntev.
Ntug Milling:Cov npoo ntawm lub phaj yog milled los xyuas kom muaj huv, meej haum -}}}}}}}}}}}}}}}}}}}}}} Up rau vuam.
Txoj Kev (Dabtsi Yog Khoov):Lub phaj yog nce zuj zus nyob rau hauv ib qho nias los tsim ib qho "j" duab, tom qab ntawd "C" C "C" C ", thiab thaum kawg qhib" O ". Qhov kev kawm maj mam ua rau cov yeeb nkab polras nrog kev ntxhov siab tsawg.
Vuam (pom):Qhib sab npoo yog kaw thiab ruaj ruaj vuam yog ua siv covSubmerged Arc Vuamtxheej txheem. Qhov no cuam tshuam:
Ib lub arc hluav taws xob raug tsoo hauv qab daim pam ntawm granular fusible flux.
Flux melts, tsim lub tiv thaiv cov txheej tiv thaiv thiab thaiv cov ntaub thaiv weld los ntawm covmosceric kis.
Qhov no ua rau muaj kev sib sib zog nqus, siab - zoo, thiab muaj zog weld.
Nthuav (sizing):Welded yeeb nkab yog siv hlau lossis hydraulic nthuav ("e" hauv jcoe). Qhov theem tseem ceeb no:
Ua kom ntseeg tau ib puag ncig hla -} seem.
Txhim kho qhov tseeb ntawm qhov tseeb.
Relieves sab hauv kev ntxhov siab los ntawm kev tsim thiab vuam cov txheej txheem.
Kuaj thiab tshuaj xyuas:Cov yeeb nkab undergoes nyuaj sim, suav nrog:
Tsis - Kev sim tshuaj (ndt):Kev sim ultrasonic (et) lossis xov xwm ntsuas (RT) ntawm Weld Seam los xyuas txhua qhov tsis zoo tag nrho.
Kev ntsuam xyuas txhua yam:Tensile, flattening, thiab flaring kev sim kom paub tseeb kev ua siab loj thiab lub zog.
Hydrostatic kuaj:Tso tawm nrog dej los xyuas nws lub peev xwm los tuav lub siab (yog tias yuav tsum tau).
Kawg ntsib thiab txheej:Cov yeeb nkab xaus yog txiav kom ntev thiab bevelled yog tias xav tau. Lub tsho loj sab nraud (piv txwv li, primer) feem ntau tau thov rau corrosion tiv thaiv thaum lub sijhawm cia thiab thauj khoom.
3. Cov qhab nia ntawm li 1163 rau lsaw kav
Tus qauv txhais tau ob peb qib kawm raws li tsawg kawg yog lub zog muaj zog (qhov kev ntxhov siab ntawm cov khoom pib ua kom muaj kev tawm tsam plastically). Cov qib kawm rau LSAWW kav suav nrog:
C250:Yam tsawg kawg nkaus los lub zog ntawm 250 MPa. Ib tug dav - lub hom phiaj qib.
C350:Yam tsawg kawg nkaus los lub zog ntawm 350 MPA. Lub siab - lub zog qib, muaj ntau rau cov qauv txheej txheem thiab trusses.
C450:Yam tsawg kawg nkaus los lub zog ntawm 450 MPa. Siv rau hauv cov ntawv thov uas yuav tsum tau muaj zog heev - rau {{3} Qhov hnyav sib piv.
"C" txhais tau tias qib yog tsim nyog rautxias - kev sib sau.
4. Cov yam ntxwv tseem ceeb & Cov txiaj ntsig
Qhov ntau thiab tsawg tshaj:LSAWaw kav tuaj yeem tsim nyob rau hauv ntau diameters (feem ntau los ntawm 16 ntiv nplhaib / 4025 hli lossis ntau dua cov phab ntsa, uas ERW kav tsis tuaj yeem ua tiav.
Lub zog siab:Cov txheej txheem pom thiab kev siv ntawm qhov siab -} Lub zog hlau ua rau hauv cov yeeb nkab nrog cov khoom siv neeg kho zoo tshaj plaws.
Qhov Tseeb Docensional:Cov txheej txheem nthuav dav ua kom meej meej kev sib tw zoo heev thiab muaj qhov ntev.
High - Zoo Weld:Lub submerged Arc Weld yog zoo dua hauv kev ua tau zoo, muaj zog, thiab kev ntseeg tau piv rau lwm txoj kev vuam zoo li ERW.
Haum rau cov ntawv thov tseem ceeb:Lawv lub zog ua rau lawv zoo tshaj rau kev thov cov txheej txheem thiab cov kev siv tshuab.
5. Kev thov
Raws li 1163 lsaw kav yog feem ntau siv nyob rau hauvyam xwm txheejthiabkev tsa tsevCov Ntawv Thov:
Lub tsev kev tsim kho:Txhua, kab teeb, thiab trusses hauv cov tsev lag luam, chaw ua haujlwm, tshav dav hlau, thiab siab {}} NCO TXAJ.
Muaj cov txheej txheem:Txhawb nqa ntas rau cov nroj tsuag muaj kev muaj muag, mining cov chaw, thiab conveyor tshuab.
Choj tsim kev tsim:Raws li pawg, piers, thiab cov tswv cuab.
Tubrog Tubrog Tubrog Tubrus:Piling rau cov warves, jetties, thiab ntug dej hiav txwv.
Hnyav Machinery:Raws li cov khoom siv hauv kev sib xyaw thiab kev ua liaj ua teb cov txheej txheem siab uas yuav tsum muaj kev ntseeg siab.
* Nco tseg: thaum LSAWaw kav tuaj yeem siv rau tsawg - qhov kev sib kis kua dej tsawg, lawv txoj kev ua lag luam tseem ceeb yog cov qauv. Txog siab - cov roj siab thiab roj pipelines, API 5L tus qauv muaj ntau dua. *
