Cov qhab nia xaiv tau
- P11 muaj cov nqi qis dua P9, muaj cov txheej txheem vuam yooj yim uas tsis tas yuav tsum tau ua nruj me ntsis tom qab-weld kho cua sov, thiab tsim nyog rau nruab nrab- kub, nruab nrab- siab boiler dej phab ntsa, qis- kub superheaters, thiab cov txheej txheem petrochemical txheej txheem piping.
- P91 muaj qhov tso cai rau kev ntxhov siab ntawm 600℃uas yog ntau dua 30% siab dua li ntawm P9, ua kom 20% -30% txo cov yeeb nkab phab ntsa tuab; Qhov no txo qis qhov hnyav thiab qhov ntim ntawm cov khoom siv vuam vuam xav tau, ua rau nws tsim nyog rau cov boilers supercritical.
- P22 muaj qhov siab tshaj plaws kev pab cuam kub ntawm 575℃thiab superior siab - kub lub zog thiab corrosion kuj piv rau P11; Txawm li cas los xij, nws tsuas yog tsim nyog rau nruab nrab- rau- cov kab mob siab tsis zoo uas tsis muaj corrosivity thiab tsis tuaj yeem hloov P9 nyob rau hauv siab - kawg, siab - kub, thiab cov ntawv thov corrosive heev.

FAQ
Q: Puas yog P9 yeeb nkab yuav tsum tau tom qab-weld cua sov kho?
A: Yog, kiag li. Txhawm rau tiv thaiv kev tawg thiab rov ua kom tawv tawv, P9 yeeb nkab yuav tsum tau xa tawm -weld pretreatment.
Q: Qhov txawv ntawm P9 thiab P91 kav dej yog dab tsi?
A: P9 muaj cov ntsiab lus chromium thiab molybdenum qis dua P91, ua rau nws tsis tshua kim thiab haum rau nruab nrab qhov kub thiab txias, thaum P91 haum rau siab -siab thiab siab - qhov kub thiab txias.
Q: Yuav ua li cas corrosion kuj ntawm P9 piv rau stainless hlau (304/316)?
A: P9 muaj kwv yees li 9% chromium cov ntsiab lus, ua rau nws haum rau siab - kub, qhuav, los yog chav ib puag ncig, tab sis tsis yog rau qis - kub acidic, chlorine - nplua nuj, los yog ntub corrosive ib puag ncig.
