P355Q Siab Vessel Phaj Qhia ntxaws qhia
P355Q steel phaj yog European txheem tempered thiab weldable zoo grain steel phaj, uas yog siv rau cov khoom siv siab. Tus naj npawb "355" qhia qhov qis qis ntawm cov khoom muaj zog ntawm lub thawv steel phaj. P355Q steel phaj siv tus qauv EN10028-6: 2017.
Kev tsim ntawm P295GH siab nkoj steel phaj
Hauv kev tsim cov txheej txheem, P295GH European txheem siab lub nkoj steel phaj yuav tsum tau mus los ntawm ntau yam txheej txheem, xws li txiav, sib sau, vuam, thiab lwm yam. kev khiav hauj lwm tsis thiab txheej txheem txheej txheem. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem vuam, nws yog ib qho tsim nyog los xaiv txoj kev vuam tsim nyog thiab cov khoom siv vuam los xyuas kom meej tias qhov zoo thiab kev ua tau zoo ntawm cov welded sib koom ua ke nrog cov khoom siv hauv paus.
Cov tsis tseem ceeb ntawm P355Q Siab Vessel Phaj yog raws li hauv qab no
1. Lub zog siab: P355NH petrochemical steel phaj muaj lub zog muaj zog thiab lub zog tensile, thiab tuaj yeem tiv taus siab dua thiab tensile quab yuam kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv.
2. Corrosion kuj: Los ntawm kev ntxiv ib qho nyiaj ntawm chromium, npib tsib xee thiab lwm yam khoom hauv cov hlau, P355NH petrochemical steel phaj muaj corrosion kuj zoo, tuaj yeem tiv taus kev yaig ntawm ntau cov kua qaub, alkali, ntsev thiab lwm yam tshuaj lom neeg, thiab txuas ntxiv kev pabcuam. lub neej ntawm cov khoom siv.
3. Kev ua haujlwm kub qis: P355NH petrochemical steel phaj tseem tuaj yeem tswj tau zoo toughness thiab ductility nyob rau hauv qhov kub thiab txias ib puag ncig, thiab tsis yooj yim rau nkig tawg, uas yog haum rau qee cov khoom siv petrochemical uas xav tau kev khiav hauj lwm hauv qhov kub thiab txias.
4. Vuam kev ua tau zoo: P355NH petrochemical steel phaj muaj vuam zoo, yooj yim rau txheej txheem thiab vuam rau ntau yam khoom siv, thiab vuam seam zoo yog siab, uas tuaj yeem ua tau raws li kev tsim khoom ntawm ntau yam qauv.
