Kev Paub Txog Engineering
Sulfuric Acid Service
Ntau cov sulfuric acid cia tso tsheb hlau luam uas yav tas los siv 316L tau ntsib kev xeb sai. Hloov lawv nrog Alloy 20 nce kev pab cuam lub neej thaum txo kev txij nkawm zaus.
Puas yog Alloy 20 tsim nyog tus nqi ntxiv tshaj 316L?
Hauv ntau daim ntawv thov sulfuric acid, yog.
Txawm hais tias Alloy 20 feem ntau raug nqi 2-3 npaug ntau dua 316L stainless hlau, nws tuaj yeem txuas ntxiv cov cuab yeej siv lub neej hauv thaj chaw corrosive acid. Ntau cov nroj tsuag tshuaj tau pom tias hloov tsis tau 316L cov hlab ntsha lossis cov khoom siv hluav taws xob hloov pauv txhua ob peb xyoos yog kim dua li kev nqis peev hauv Alloy 20 thawj zaug.
Alloy 20 puas tuaj yeem hloov Hastelloy C276?
Qee zaum -tab sis tsis tas li.
Yog tias cov txheej txheem nruab nrab yog sulfuric acid, Alloy 20 feem ntau yog qhov kev xaiv pheej yig dua. Txawm li cas los xij, rau cov khoom siv uas muaj cov concentrated hydrochloric acid, cov chlorine ntub dej, cov tshuaj hypochlorite, los yog kev sib xyaw ua ke -acid ib puag ncig, Hastelloy C276 tseem yog cov khoom nyiam.
Puas Alloy 20 xav tau PWHT tom qab vuam?
Feem ntau, tom qab-weld kev kho cua sov tsis tas yuav tsum tau ua kom zoo welded Alloy 20 vim tias niobium stabilization txo rhiab heev.
Puas yog Alloy 20 haum rau cov concentrated sulfuric acid?
Alloy 20 ua tau zoo heev nyob rau hauv ntau daim ntawv thov sulfuric acid, tshwj xeeb tshaj yog nyob rau hauv qis rau nruab nrab kub. High concentrations ntawm qhov kub siab: Corrosion tus nqi tuaj yeem nce sai
Dab tsi muab hlau yuav tsum siv rau Alloy 20 vuam?
- ER 320 LR
- ERNiCrMo-3 (rau cov pob qij txha sib txawv lossis thaum yuav tsum tau txhim kho corrosion kuj)
Tus nqi optimization
Rau cov khoom siv tsuas yog kis rau cov xov xwm me me, 316L tseem yog qhov kev xaiv pheej yig dua. Alloy 20 dhau los ua tus nqi- ua haujlwm tau zoo thaum txo qis hauv corrosion- ntsig txog kev poob qis thiab kev saib xyuas offsets nws cov nqi pib ntau dua.
Kev hloov khoom siv
Yog tias Alloy 20 tawm ntawm cov peev nyiaj lossis cov khoom lag luam, xav txog 904L ua lwm txoj hauv kev, txawm tias nws muaj qhov sib txawv me ntsis sulfuric acid. Tham nrog tus kws tsim khoom siv rau koj qhov tshwj xeeb concentration / kub nkhaus.

FAQ:
Alloy 20 stainless hlau siv rau dab tsi?
- Alloy 20 (UNS N08020) daim hlau, cov ntawv, thiab cov coils tau teev tseg rau cov khoom siv tshuaj ua haujlwm tuav sulfuric acid, tshuaj thiab zaub mov- qib nkoj, thiab cov khoom sib xyaw ua ke.
Dab tsi yog qhov txawv ntawm Alloy 20 thiab 316L stainless hlau?
- Alloy 20 muaj 32-38% nickel piv rau 8-10% hauv 316L, ntxiv rau 3-4% tooj liab uas 316L tsis tag nrho. Qhov no txhais tau tias zoo dua corrosion kuj nyob rau hauv sulfuric acid, phosphoric acid, thiab chloride ib puag ncig.
Qhov txawv ntawm Alloy 20 thiab Incoloy 825 yog dab tsi?
