Hauv lub ntiaj teb kev tsim kho kev lag luam uas hloov pauv tas li, qhov kev thov rau cov kav dej uas txhim khu kev qha thiab ruaj khov txuas ntxiv mus. Txhawm rau daws qhov kev xav tau no, peb lub vev xaib muaj kev txaus siab muab ntau yam yeeb nkab hlau zoo, suav nrog cov uas tau hwmASTM A335 P91, P5, P9, thiab ntau lwm tus, los ua kom tau raws li ntau yam kev xav tau ntawm kev lag luam.
Ntawm peb cov khoom muag ntau yam, ASTM A335 P91 yeeb nkab sawv tawm ua ib qho ntawm cov kev xaiv uas neeg xav tau tshaj plaws. Lub npe nrov rau nws lub zog kub thiab tiv taus xeb, nws tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev siv boiler. Peb cov yeeb nkab ASTM A335 P91 ua kom muaj kev ua haujlwm zoo tshaj plaws hauv qab qhov kub thiab txias, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem kev lag luam tseem ceeb.
Rau cov neeg uas nrhiav kev ua tau zoo tshaj plaws nrog rau kev ruaj khov, ASTM A335 P5 alloy steel yeeb nkab yog qhov kev xaiv zoo heev. Cov yeeb nkab hlau alloy seamless no muaj qhov zoo kawg nkaus weldability thiab formability, ua rau nws yog qhov kev xaiv nrov rau ntau yam kev siv, los ntawm cov tshuab boiler mus rau cov kav dej kub siab.
Cov yeeb nkab ASTM A335 P9 yog lwm lub pob zeb diamond hauv peb cov khoom sau, ua kev zoo siab rau nws qhov tiav zoo heev thiab kev tiv taus oxidation thiab scaling zoo heev ntawm qhov kub siab. Nws yog dav siv hauv cov chaw tsim hluav taws xob thiab kev lag luam petrochemical vim nws qhov kev sib xyaw ua ke ntawm lub zog thiab kev ua haujlwm ntev.
Hauv peb lub vev xaib, peb nkag siab tias cov haujlwm sib txawv xav tau cov kev cai tshwj xeeb, yog vim li cas peb thiaj muab covASTM A213 yeeb nkab.
Tsim los kom tiv taus qhov kub thiab txias thiab qhov chaw xeb, ASTM A213 yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev ua haujlwm zoo.
Peb txoj kev cog lus rau kev ua tau zoo tshaj plaws txuas ntxiv mus rau ntau yam khoom. Rau cov ntawv thov txheem, peb muab covASTM A106 yeeb nkab, ib qho kev xaiv ntau yam uas paub txog nws qhov tiav tsis muaj qhov tsis xws luag thiab qhov tseeb ntawm qhov ntev.
Ua ib qho chaw nres tsheb rau cov yeeb nkab hlau sib xyaw, peb muaj kev txaus siab rau kev muab cov yeeb nkab hlau sib xyaw 15crmo, uas paub zoo txog nws lub zog tensile zoo heev thiab tiv taus kev hnav thiab rhuav. Cov yeeb nkab no yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm uas xav tau ob qho tib si ruaj khov thiab kev siv nyiaj tsim nyog.
Ntxiv rau cov khoom lag luam uas tau hais los saum toj no, peb kuj muab ntau yam yeeb nkab P5 alloy, P9 alloy yeeb nkab, thiab T91 alloy steel yeeb nkab, txhua yam tau tsim los kom tau raws li cov kev xav tau tshwj xeeb ntawm kev lag luam.
Hauv peb lub vas sab hauv internet, peb muab qhov tseem ceeb rau kev txaus siab rau cov neeg siv khoom thiab ua ntau yam haujlwm kom muab tau qhov zoo tshaj plaws thiab kev pabcuam zoo tshaj plaws. Nrog lub koob npe nrov rau kev xa khoom raws sijhawm thiab tus nqi sib tw, peb tau txais kev ntseeg siab ntawm ntau tus neeg siv khoom thoob ntiaj teb.
Hauv kev xaus, thaum nws los txog rau kev muag khoomcov kav hlau sib xyaw ua ke siab, peb lub vev xaib tseem yog qhov chaw kawg. Nrog peb cov khoom lag luam sib txawv, suav nrog ASTM A335 P91, P5, P9, thiab lwm yam yeeb nkab hlau zoo tshaj plaws, peb txuas ntxiv txhawb nqa kev lag luam nrog cov kev daws teeb meem txhim khu kev qha uas tiv taus kev sim ntawm lub sijhawm thiab cov xwm txheej hnyav.
