Boiler Yeeb Nkab
Boiler tubes yog ib qho ntawm cov yeeb nkab seamless.Txoj kev tsim khoom yog tib yam li seamless raj, tab sis nws muaj cov kev cai nruj rau kev tsim cov kav hlau.Raws li qhov ntsuas kub, lub raj boiler tau muab faib ua cov raj boiler dav dav thiab lub siab siab boiler raj.
Txoj kev tsim khoom:
① dav dav boiler raj kub yog qis dua 450 ℃, siv cov yeeb nkab kub dov los yog txias drawn tube tsim steel yeeb nkab.
② lub siab kub boiler raj feem ntau yog siv nyob rau hauv tej yam kev mob ntawm high kub thiab siab siab yeeb nkab, cov nyhuv ntawm kub flue roj thiab dej vapor, oxidation thiab corrosion.Cov yeeb nkab steel nrog lub zog siab tawg, siab tiv taus oxygen corrosion thiab muaj kev ruaj ntseg zoo.
Boiler tubes hom phiaj:
① dav dav boiler raj yog tsuas yog siv los tsim cov phab ntsa hauv dej, cov hlab hauv cov dej kub npau npau thiab cov yeeb nkab uas muaj cua sov super, cov kav dej kub boiler, cov yeeb nkab loj thiab me me thiab cov yeeb nkab arch cib.
② high-pressure boiler raj yog tsuas yog siv los tsim kev kub siab thiab ultra-siab siab boiler super rhaub tubes, reheat tubes, pa taws, lub ntsiab chav yeeb nkab.
Qeb:
General boiler hlab thiab siab siab boiler raj boiler raj yog raug rau kub kub kev kawm.Boiler raj feem ntau, los yog lub siab-siab boiler raj raws li lawv siv tau muab faib ua ntau yam steel yeeb nkab.
Cov qauv thiab cov khoom siv rau cov yeeb nkab steel yog muaj nyob rau ntawm carbon, alloy, thiab stainless hlau khoom.
