1. Dab tsi yog qhov kev siv tseem ceeb ntawm Incoloy 800 seamless thiab welded raj?
Teb:
Incoloy 800 raj yog siv nyob rau hauv siab -kub thiab corrosive ib puag ncig, suav nrog:
Thaum tshav kub kub exchangers thiab boiler tubing nyob rau hauv fais fab nroj tsuag
Chemical thiab petrochemical ua khoom siv
Rauv thiab rhaub tubing rau siab - qhov kev pab kub
Roj thiab roj pipelines thiab cov txheej txheem kab
Nuclear thiab marine daim ntaub ntawv yuav tsum tau corrosion kuj thiab lub zog
2. Dab tsi ua rau Incoloy 800 cov raj zoo dua li cov pa roj carbon steel?
Teb:
Kev tiv thaiv zoo heev rau oxidation thiab carburization ntawm qhov kub siab
High nickel thiab hlau cov ntsiab lus txhim kho txhua yam muaj zog thiab corrosion kuj
Resistant rau kev nyuaj siab corrosion cracking thiab pitting nyob rau hauv oxidizing thiab me ntsis txo ib puag ncig
Ua tau zoo dua 304/316 stainless hlau nyob rau hauv ntev - lub sij hawm siab - kub ua hauj lwm
3. Dab tsi yog cov khoom tseem ceeb ntawm Incoloy 800 seamless thiab welded raj?
Teb:
Tensile zog: 480-620 MPa (nyob ntawm seb qhov loj me thiab kev kho cua sov)
Tawm zog: 210-310 MPa
Elongation: 30-40%, tso cai rau kev yooj yim hauv kev tsim thiab kev teeb tsa
Zoo heev creep thiab qaug zog tiv thaiv rau lub sij hawm siab siab - kub kev pab cuam
Seamless raj muab siab siab kam rau ua; welded raj yog tsim rau loj diameters los yog qis zog tshuab
4. Yuav ua li cas Incoloy 800 raj yuav tsim los yog ntsia?
Teb:
Vuam: Siv cov nickel{0}}raws li cov hlau; preheating feem ntau tsis tas yuav tsum tau
Khoov / sib sau: tuaj yeem ua txias lossis kub tsim; annealing yuav siv tau los kho cov ductility tom qab hnyav deformation
Txiav: Plasma, laser, lossis dej dav hlau txiav pom zoo kom tsis txhob muaj cua sov- thaj chaw cuam tshuam
Seamless vs Welded: Seamless raj yog nyiam rau siab - kev siv siab; welded raj yog tus nqi -zoo rau nruab nrab siab los yog loj diameters
5. Dab tsi yuav tsum tau xav txog thaum xaiv Incoloy 800 raj rau ib qhov project?
Teb:
Kev khiav hauj lwm kub: Haum rau daim ntaub ntawv mus txog ~ 700 degree; 800HT variant nyiam rau ntev ntev -kub raug
Corrosive ib puag ncig: Zoo heev rau oxidizing thiab txo qis ib puag ncig; tshawb xyuas tshuaj lom neeg
Mechanical load thiab siab: Seamless raj rau kev kub siab, welded hlab rau qis siab
Fabrication Requirements: Xav txog kev khoov, sib sau, thiab vuam xav tau
Tus nqi -kev ua tau zoo: Tus nqi pib ntau dua li cov hlau tsis muaj steel, tab sis ntev - lub sij hawm durability txo cov nqi kho thiab hloov cov nqi
