    ib.Txoj kev deoxidation yog tsim raws li hauv qab no:

    FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al).

    b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb.

    Hydrostatic Test

    Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj los ntawm cov chaw tsim khoom mus rau lub siab hydrostatic uas yuav tsim nyob rau hauv cov yeeb nkab phab ntsa ib qho kev ntxhov siab tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog ntawm chav tsev kub.Lub siab yuav tsum tau txiav txim los ntawm qhov sib npaug hauv qab no:
    P = 2st/D

    Permissible variations In Weights and Dimensions

    Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau ntsuas nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 10% tshaj lossis 5.5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
    Sab nraud txoj kab uas hla yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub npe nominal sab nraud txoj kab uas hla
    Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis pub ntau tshaj 12.5% ​​raws li cov phab ntsa thickness

    Helical Welded Yeeb Nkab

    1. Nkag siab S355 JR kauv steel yeeb nkab:

    S355 JR kauv steel yeeb nkabyog ua los ntawm cov qib siab S355JR steel thiab yog ib qho kauv seam yeeb nkab tshwj xeeb tsim rau kev siv roj pipeline siv.Lub kauv seam qauv muab cov raj xa dej zoo heev thiab yooj yim, ua rau nws zoo tagnrho rau kev sib kis mus ntev thiab kev thauj mus los ntawm cov pa roj.Nws cov robustness ua kom muaj kev tiv thaiv rau lwm yam xws li hauv av txav, seismic kev ua si thiab av corrosion, yog li ua kom lub neej ntev thiab kev ncaj ncees ntawm cov raj xa hluav taws xob.

    2. Kev nyab xeeb ua ntej:

    Kev ntseeg siab thiab kev nyab xeeb ntawm cov raj xa hluav taws xob yog qhov tseem ceeb rau kev noj qab haus huv ntawm cov zej zog thiab ib puag ncig.Lub zog zoo dua thiab ua haujlwm ntev ntawm S355 JR kauv steel yeeb nkab ua lub luag haujlwm tseem ceeb hauv kev txo qis kev pheej hmoo ntawm kev xau, tawg thiab kev sib tsoo tom ntej.Ua tsaug rau nws txoj kev siv cov hlua khi, cov yeeb nkab cov qauv kev ncaj ncees tseem nyob zoo txawm tias nyob rau hauv qhov nyuaj los yog huab cua huab cua.Kev sib xyaw cov kav dej no rau hauv cov raj xa hluav taws xob zoo ua rau txo qhov muaj peev xwm ntawm ib puag ncig kev phom sij thiab tso cai rau tsis muaj kev cuam tshuam ntawm cov pa roj ntsha mus rau cov neeg siv kawg.

    3. Durability ntawm sustainable infrastructure:

    Qhov ua tau zoo tshaj plaws ntawm S355 JR kauv steel yeeb nkab ua kom lub neej ntev ntawm koj cov kav dej xa hluav taws xob, txuag kev saib xyuas thiab hloov cov nqi dhau sijhawm.Lub raj xa dej yog ua los ntawm qib siab S355JR steel, uas muaj kev tiv thaiv corrosion zoo heev, cuam tshuam tsis kam thiab hnav tsis kam.Qhov kev tiv thaiv no txo ​​cov kev kho thiab hloov pauv, yog li txo cov kev cuam tshuam ib puag ncig thiab cov pa roj carbon emissions cuam tshuam nrog kev kho kav dej thiab kev tsim kho dua tshiab.Lub neej ntev ntawm S355 JR kauv steel yeeb nkab ncaj qha ua rau muaj kev nyab xeeb dua thiab ib puag ncig zoo rau cov kav dej.

    4. Txhim kho kev thauj mus los:

    Kev ua tau zoo hauv kev thauj mus los ntawm cov roj av muaj peev xwm txo qis zog thiab ua kom muaj peev xwm kis tau zoo.Lub kauv seam qauv ntawm S355 JR kauv steel yeeb nkab tso cai rau du, tas li cua ntws, txo kev sib txhuam poob thaum ua kom lub raj xa dej muaj peev xwm thauj mus los.Cov yeeb nkab muaj ib qho chaw sab hauv uas ua kom pom kev zoo ntawm cov dej ntws tawm, yog li txo kev siv hluav taws xob thiab ua kom muaj txiaj ntsig zoo.Tsis tas li ntawd, cov yeeb nkab lub teeb yuag ua rau kev tuav, kev thauj mus los thiab kev teeb tsa tau yooj yim dua, txuag lub sijhawm thiab nqi thaum tsim kho.

    Xaus:

    Kev sib koom ua ke S355 JR kauv steel yeeb nkab rau hauv kev tsim cov pa roj carbon monoxide tau raug pov thawj los txhim kho kev ua haujlwm zoo.Lub raj xa dej muaj zog tshwj xeeb, kev ua haujlwm ntev thiab kev nyab xeeb ua kom yooj yim rau seamless ntws ntawm cov pa roj carbon monoxide, txo cov kev pheej hmoo ntawm kev raug mob, kev phom sij ib puag ncig thiab cov nqi kho.Los ntawm kev ua kom zoo dua kev thauj mus los thiab txo qis zog poob, lub raj xa dej ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li qhov xav tau ntawm lub zog loj hlob thaum tuav cov kev coj ua kom ruaj khov.Kev nqis peev hauv cov kev daws teeb meem tshiab xws li S355 JR kauv steel yeeb nkab yog qhov tseem ceeb rau tsoomfwv, kev lag luam thiab cov zej zog kom muaj kev ntseeg siab, muaj txiaj ntsig zoo thiab ua rau txoj hauv kev rau lub zog huv si yav tom ntej.
