Boiler steel raj thiab kav dej yog siv rau boiler vaj tse thiab tshav kub exchangers
Boiler Style Hlab Thiab Cov Kav Pipes, Hais Txog Qhov Kawg Thiab Qhov Ntev Thiab Cov Khaub Ncaws Kub, Raws Li Cov Tub Ntsu Hlau, Steel raj Specifications Nrog Rau Sab Nraud Qhov loj me (xws li txheej txheej hla lossis sab ntev ntev) thiab phab ntsa tuab, nws qhov loj me ntawm cov kab mob capillary rau lub cheeb ntawm ob peb meters ntawm cov yeeb nkab loj.Cov cuab yeej siv hlau siv tau rau cov khoom siv, cov khoom siv thermal, kev tshawb nrhiav cov roj av, cov roj av, cov hom phiaj tshwj xeeb.
Boiler steel voos thiab kav dej khawb av, muab faib seamless steel yeeb nkab thiab welded steel yeeb nkab (leeg yeeb nkab) ob pawg.Raws li ntu cov duab tuaj yeem faib ua cov raj thiab lub voos xwmfab tshwj xeeb, tab sis muaj ob peb lub square hlau, tab sis sib npaug tshwj xeeb-raj.Rau cov yeeb nkab steel nyob rau hauv dej siab los sim tawm hydraulic kev ntsuas thiab kev nthuav dav, hauv qab cov yeeb nkab steel raws li cov qauv lossis cov cai ntawm kev kuaj sab, flaring Kuaj, mob siab ntso kuaj.
Boiler Steel Hlab Thiab Cov Kav, Qauv Ntau Lawm
Boiler txheej txheem steel voos thiab kav dej, yog hom ntawm seamless raj.Txoj kev tsim khoom yog tib yam li seamless yeeb, tab sis muaj cov cai nruj ntawm hom steel siv los tsim cov hlau yeeb.Raws li kev siv ntsuas kub tau muab faib ua ob hom kev ua haujlwm boiler boiler boiler thiab kev kub siab boiler raj.
Boiler steel voos thiab kav dej, cov cuab yeej cuab tam ua yog qhov tseem ceeb ntsuas kom ntseeg tau qhov kawg serviceability ntawm cov hlau.Nws nyob ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau thiab cov kev kho cua sov.Nyob rau hauv tus qauv yeeb nkab steel, raws li kev siv ntau yam, tawm suab, ua lub zog, raws li cov neeg siv kev xav tau ntawm kev ua tau siab thiab kub.
① Lub Tube Boiler ROULTION BOILER kub nyob qis dua 350 ℃, yeeb nkab nyeg yog ua los ntawm No.20 Carbon Steel Kub Rolled yeeb nkab los yog txias drawn yeeb nkab.
② Cov leeg Boiler siab feem ntau siv hauv kev kub siab thiab cov xwm txheej siab.Nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, oxidation thiab corrosion yuav tshwm sim.Lub Yeeb Nkab Steel yog yuav tsum muaj lub zog ruaj khov, siab oxidation corrosion tsis kam thiab zoo microstructure kev ruaj khov
Boiler cov ntaub pua ntoo hlau ib sab thiab kav dej, siv
