SA302GrB steel phaj yog ib hom Molybdenum alloy steels hauv ASME SA302 / SA302M, SA302 Qib B yog tag nrho sib npaug rauA302 Qib BHauv ASTM A302 / A302 steel specification.Txawm li cas los xij steel qib twg hauv Suav steel specification yog sib npaug rau SA302 Qib B steel phaj?
Kev sib piv cov cuab yeej cuab tam thiab tshuaj lom neeg muaj pes tsawg leeg los ntawm cov lus hauv qab no, peb pom 15CrMoR steel phaj hauv steel qauv GB / T713 rau boiler lub tsev siv steels zoo ib yam liSA302GRB steel phaj.Lawv txhua tus xav tau Mo % saum toj no 0.45% thaum muab khoom thiab kev kho cua sov nrog Normalized.Llse,15CrMoR steel phajmuaj kev txwv ntau dua rau P% thiab S% thaum dov.
SA302 Qib A steel phajsiv rau kev tsim cov boilers thiab siab hlab ntsha nrog Mo (Min.0.45%) alloy.15CrMoR steel phaj kuj siv rau boilers thiab nrog Mo alloy nyob rau hauv 0.45-0.6% nyob rau hauv lub tshav kub tsom xam dov.
Kev sib piv hauv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv dag zog hauv cov lus hauv qab no, nyob rau hauv feem ntau qhov xwm txheej, SA302 Qib A steel phaj yog sib npaug rau 15CrMoR steel phaj thaum tsim boilers thiab cov hlab ntsha siab.

Daim Ntawv Thov Scenario: Sib npaug hauv Kev Xyaum & Kev Taw Qhia Kev Xaiv
Ob leegSA302GrB siab nkoj steel phajthiab15CrMoR kub dov steel phajyog dav siv nyob rau hauv boilers, siab hlab ntsha, thiab tshav kub exchangers, nrog rau lawv sib npaug validated nyob rau hauv ntau yam kev lag luam tej yaam num:
Cov ntawv thov ntawm SA302GrB
Txawv Teb Chaws ASME-cov haujlwm tau ntawv pov thawj: Petrochemical reactors, natural gas processing pressure vessels, thiab boiler superheater tubes.
Siab-siab, qis- qhov kub thiab txias: Hydrogenation reactors, LNG cog cov cuab yeej pab, thiab thermal fais fab nroj tsuag siab - cov cua sov.
Qhov zoo: Kev lees paub thoob ntiaj teb tus qauv yooj yim hla- ciam teb kev yuav khoom thiab daim ntawv pov thawj qhov project, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm EPC thoob ntiaj teb.
Cov ntawv thov ntawm 15CrMoR
Hauv tsev GB-cov haujlwm txheem: Coal- tua hluav taws xob cog boiler nruas, tshuaj lom neeg kev lag luam methanol synthesis reactors, thiab dej phwj kho cov hlab ntsha.
Corrosive siab- ib puag ncig kub: Cov khoom siv sulfuric acid ntau lawm, hydrogen sulfide kho yees, thiab khib nyiab incineration boiler tshav kub txauv Cheebtsam.
Qhov zoo: Tus nqi -kev ua tau zoo (10-15% qis dua SA302GrB) thiab cov khoom lag luam loj hauv tsev, tsim nyog rau cov haujlwm hauv tsev nrog kev tswj hwm tus nqi nruj.
