Rhuav lub npe
Lub npe nws tus kheej yog txoj cai uas qhia koj txhua yam txog cov yeeb nkab cov khoom thiab tsim qauv:
S355: Qhov no yog tusteem nqintawm cov hlau. Tus 's' sawv rau "cov qauv" hlau. Tus lej '355' qhia txog tusYam tsawg kawg nkaus xwb ZogNtawm cov hlau, uas yog 355 megapascals (MPa) lossis kwv yees li 355 n / mm². Qhov no txhais tau tias cov hlau tuaj yeem tiv taus ntau qhov kev ntxhov siab tseem ceeb ua ntej nws pib deform to taub tas li.
Joh: Cov Placix no qhia tau tusCov khoom siv tawv thiab sivRaws li European txheem en 10219.
J: Tsim qauv tsawg kawg v -} negch cuam tshuam lub zog ntawm 27 joules ntawm0 QibCov. Qhov no txhais tau tias cov hlau muaj qhov zoo tsis kam rau brittle baciture thaum tsis kub.
O: Sawv rau "Normalized" lossis "Nonicized dov". Nov yog tusKev Kho Cua Sovmob. Li qub koom nrog cua sov cov hlau mus rau qhov ntsuas kub tshwj xeeb thiab tom qab ntawd tso cai rau nws kom txias rau hauv huab cua. Tus txheej txheem no ua kom cov qauv sib dhos, txhim kho kev ua kom muaj zog, lub zog, thiab tag nrho cov khoom siv tshuab.
H: Sawv rau "hollow ntu". Qhov no tshaj tawm cov khoom yog npaj rau cov qauv hollow hauv (cov kav dej zoo li cov raj).
Tussaw: Qhov no yog tusCov txheej txheem tsim khoomCov. Nws sawv rauMuab kauv submerged arc vuamCov. Hauv cov txheej txheem no, ntev, txuas ntxiv cov hlua khi ntawm cov hlau (skelp) yog spirmed zoo nkauj thiab sab nraud siv cov txheej txheem arcergle arc vuam. Qhov no tsim kom muaj zog, txuas ntxiv mus ntxiv raws qhov ntev ntawm cov yeeb nkab.
Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig zoo
Siab zog - rau - qhov hnyav. Piv:Lub 555 MPa paib lub zog ua rau nws muaj zog tsis tau tus poj niam, uas yog qhov zoo tagnrho rau cov qauv loj.
Zoo tsawg - kub ceev:Lub 'J' kev ntsuas xyuas nws ua tau zoo nyob rau hauv ib puag ncig uas kub tau poob rau ib puag ncig 0 degree, ua rau nws txias thiab txias} kev kho vaj tse.
Zoo heev Weldability thiab Formaty:Cov tshuaj lom neeg muaj kuab lom ntawm S3555joh hlau yog tswj hwm kom nws yooj yim rau weld thiab fabricate yam tsis muaj kev ncaj ncees.
Tus nqi -} Siv tau zoo rau txoj kab uas loj loj loj:SSAW cov txheej txheem yog qhov ua tau zoo heev rau kev tsim loj- txoj hauj lwm uas hla hla (40 hli rau ntau dua 2,500 hli).
Qhov yooj yim tshaj plaws:SSAW cov kav dej tuaj yeem tsim tau ntev ntev, txo tus naj npawb ntawm cov teb uas xav tau nyob rau hauv ib qho project.
Cov Kev Siv Cov Ntawv Siv
S3555joh ssaw kav yog feem ntau siv nyob rau hauv hnyav - cov ntawv thov ua haujlwm:
Piling:Dav siv raws liFoundation pilesRau cov vaj tse, txuas hniav, thiab offshore qauv. Lawv lub zog thiab kav ntev ua rau lawv zoo tag nrho rau kev tsav tsheb tob hauv av.
Civil Engineering thiab kev tsim kho:Siv raws liCov Qauv Qauv Qauvthiab txhawb nqa hauv vaj tse loj, chaw ntau pob, chav tsev muaj kev nyab xeeb, thiab tus choj Piers.
Dej Kis Tau Dej:Rau qhov loj -} txoj kab uas hla thiab cov penstocks hauv cov dej num hydroelectric.
Pipelines rau cov roj thiab roj:Feem ntau siv rau onshore raj thiab offshore rajhorine tshuab rau kev thauj cov roj, roj, thiab lwm yam kua, zoo li API 5L) kuj muaj ntau nyob hauv txoj haujlwm no.
Cua Turbine Yees:Yuav siv tau rau hauv kev tsim kho pej thuam rau cov cua tshuab.
Cov Qauv Muaj Feem
S3555joh ssaw kav yog ib txwm tsim ua raws li cov qauv European, nrog cov:
EN 10219:Txias tsim Welded cov txheej txheem Hollow ntawm tsis -} Alloy aliroks.
En 10210:Kub ua tiav Welded cov txheej txheem Hollow ntawm tsis -} Alloy aliroks.
Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum cov khoom siv thiab cov neeg kho mob tau txhais los ntawm cov qauv txheej txheem (piv txwv li, kab npoo av) kuj yog cov tseem ceeb hauv cov qauv no.
Piv nrog lwm cov qib / cov txheej txheem

Tseem ceeb takaway:S3555joh muaj zoo dua qis - kub nrawm piv rau S355jrh, ua rau nws cov huab tais tsim nyog rau cov huab cua txias.
Lub ntsiab
Nyob rau hauv essence,S35555joh swsaw steel yeeb nkabyog ahigh - Lub zog, qis {- cov yeeb nkab tiv thaiv steel yeeb nkabua los ntawmMuab Weld ProgramCov. Nws yog lub tsev tsim lub tsev rau niaj hnub tsim kho, muaj nuj nqis rau nws txoj kev ntseeg tau, lub zog, thiab versatility.
Thaum ua tiav cov khoom no, nws yog qhov tseem ceeb los qhia kom meej cov qauv tiav (piv txwv li, thiab qhov yuav tsum muaj (nyob sab nraud) kom ntseeg tau tias koj tau txais cov khoom lag luam kom raug rau koj qhov project.
