Kev Siv Tseem Ceeb thiab Kev Lag Luam
Pressure Vessel Fabrication:Siv rau kev tsim cov boilers, cia cov hlab ntsha, thiab cov tso tsheb hlau luam uas tswj cov siab sab hauv thiab sab nraud, tshwj xeeb tshaj yog qhov xav tau lub zog tensile siab (xws li, raws li EN 13445).
Petrochemical thiab Chemical Industry:Zoo tagnrho rau fabricating reactors, tshav kub exchangers, thiab refinery khoom uas yuav tsum tau siab -siab ua hauj lwm.
Zog Tsim:Siv rau hauv kev tsim cov chav turbines thiab cov kav dej tseem ceeb.
Kev siv tus qauv:Vim nws toughness, nws yog siv nyob rau hauv engineered, welded Cheebtsam qhov twg high yield zog yog ib qho tseem ceeb, nrog rau cov qauv offshore.
Cov yam ntxwv tseem ceeb cuam tshuam rau kev siv
Siab zog:quenched thiab tempered (Q + T) txheej txheem muab kev txhim kho lub zog piv rau cov txheej txheem siab lub nkoj steel.
Tsawg-Tsub Toughness:P355Q variants, tshwj xeeb tshaj yog thaum teev nrog cov qib kub qis, yog haum rau qhov chaw txias.
Welding Performance:Cov qauv zoo -grained ua rau nws zoo heev weldable rau complex, tshwj xeeb cov khoom siv siab.
Cov txiaj ntsig tseem ceeb ntawm P355Q steel muaj xws li:
Siab zog thiab toughness:Raws li quenched thiab tempered (𝑄 + 𝑇) steel, nws muab lub zog tensile siab thiab zoo heev cuam tshuam toughness, ua rau nws haum rau xav tau siab- muaj cov khoom.
Zoo Weldability:Txawm hais tias nws lub zog siab, nws tau tsim tshwj xeeb los ua weldable, ua kom txhim khu kev qha ntawm cov hlab ntsha nyuaj.
Fine-Structured:Cov qauv zoo - cov nplej ua kom muaj zog, tshwj xeeb tshaj yog txo txoj kev pheej hmoo ntawm nkig tawg nyob rau hauv qis - qhov kub thiab txias.
Kev ua haujlwm zoo heev:Nws nta qhov txias txias- khoov thiab tsim muaj peev xwm, uas yooj yim rau kev tsim cov txheej txheem.
Cov cuab yeej siv siab ua raws li:Nws yog tsim los rau cov tshuab pressurized, muab cov kav ntev thiab kev nyab xeeb, nrog kev txhim kho hardness rau siab -load, siab - ib puag ncig siab.

P355Q yog dab tsi?
P355Q yog qib qis- alloy siab- lub zog steel qib. Nws ua raws li European cov qauv, muaj qhov zoo toughness, weldability thiab txhua yam khoom. Dav siv nyob rau hauv kev tsim kho, choj thiab siab nkoj tsim khoom uas yuav tsum tau txhim khu kev qha load- bearing peev.
Cov txheej txheem European twg P355Q ua raws?
P355Q ua tau raws li EN 10028 tus qauv, uas qhia txog cov kev cai rau cov khoom tiaj tus uas ua los ntawm cov khoom siv weldable zoo - cov qauv hlau. Cov txheej txheem no txhais nws cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov txheej txheem tshuaj xyuas kom ntseeg tau cov khoom zoo.
Dab tsi yog cov tshuaj tseem ceeb ntawm P355Q?
Cov tshuaj lom neeg tseem ceeb ntawm P355Q muaj xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab lwm yam. P thiab S yog tswj los ntawm qib qis kom tsis txhob brittleness. Cov kab mob xws li niobium lossis vanadium tuaj yeem raug ntxiv los txhim kho lub zog.
