Hais txogSA-213 T12cov yeeb nkab tsis sib xws φ44.5 * 5.6 cov yeeb nkab tsis sib xws cov yeeb nkab hlau sib xyaw, cov hauv qab no yog cov lus teb ntxaws ntxaws los ntawm ntau yam:
1. Txheej txheem cej luam ntawm cov khoom
SA-213 T12cov yeeb nkab tsis sib xyaw yog cov yeeb nkab hlau sib xyaw uas ua tau raws li cov qauv ntawm American Society for Testing and Materials (ASTM) thiab American Society of Mechanical Engineers (ASME). Ntawm lawv, "SA-213" sawv cev rau tus lej txheem, thiab "T12" yog qib khoom siv tshwj xeeb, uas feem ntau yog siv rau hauv boilers, superheaters, heat exchangers thiab lwm yam khoom siv hauv qab qhov kub thiab txias siab thiab qhov chaw siab.
φ44.5 * 5 cov yeeb nkab hlau txhais tau tias lub cheeb sab nraud ntawm cov yeeb nkab hlau yog 44.5 hli thiab phab ntsa tuab yog 5 hli.
2. Cov kev siv tseem ceeb
SA-213 T12cov yeeb nkab tsis sib txuas φ44.5 * 7 yog siv dav hauv cov teb hauv qab no vim nws qhov kev ua tau zoo heev:
Kev tsim khoom boiler: Ua ib qho tseem ceeb ntawm lub boiler, xws li lub superheater thiab reheater, nws tiv taus qhov kub thiab txias siab thiab cov pa roj flue.
Petrochemical: Hauv cov txheej txheem ntawm kev ua roj av, kev tsim tshuaj lom neeg, thiab lwm yam, nws yog siv los thauj cov kua dej kub thiab siab.
Kev lag luam fais fab: Hauv cov chaw tsim hluav taws xob thermal, nws yog ib qho tseem ceeb ntawm cov kav dej kub thiab siab.
3. Cov yam ntxwv ntawm cov khoom
Lub zog siab:SA-213 T12Cov yeeb nkab tsis muaj hlau sib xyaw muaj lub zog tensile siab thiab lub zog tawm los, thiab tuaj yeem tiv taus lub zog sab hauv loj thiab lub zog sab nraud.
Kev tiv thaiv xeb: Hauv qhov chaw nyuaj thiab txawm tias qhov chaw hnyav, cov yeeb nkab hlau ua rau muaj kev tiv thaiv xeb zoo, uas ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua. Cov lus qhia me me muaj nyob hauv Tshuag hauv cov khoom me me, thiab cov khoom muag hloov pauv txhua hnub. Koj tuaj yeem tiv tauj Chenggang Lag Luam kom tau txais kev sab laj.
Kev vuam zoo: Nws tsis yooj yim kom muaj teeb meem xws li tawg thiab qhov hws thaum vuam, uas ua kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm qhov sib koom ua ke.
Kev ua haujlwm ruaj khov: Tom qab kev kho cua sov tshwj xeeb, cov yeeb nkab hlau muaj kev teeb tsa ruaj khov thiab kev ua haujlwm, ua kom muaj kev nyab xeeb ntawm kev siv mus sij hawm ntev.
