Common Production Standards
Ob lub alloys yog tsim nyob rau hauv nruj thoob ntiaj teb kev tswj lub moj khaum nyob ntawm seb cov khoom hom:
Tube & Tubes:ASTM B622 (Seamless), ASTM B619 / ASME SB619 (Welded)
Fittings & Flanges:ASTM B366, ASTM B564 / ASME SB564
Bars & Rods:ASTM B574 / ASME SB574

Corrosion Resistance: Oxidizing vs. Txo ib puag ncig
Cov qib sib txawv ntawm chromium thiab molybdenum dictate yuav ua li cas txhua cov hlau ua haujlwm hnyav corrosion profiles.
Oxidizing thiab Aggressive Aqueous Media (Alloy C22 Advantage)
Vim tias Alloy C22 muaj cov qib chromium ntau dua, nws pom tau tias muaj kev tiv thaiv zoo heevoxidizing ib puag ncig. Nws muaj kev tiv thaiv zoo rau cov chlorine ntub dej, nitric acid sib tov, thiab cov kab mob oxidizing acid uas muaj ferric lossis cupric ions. Tsis tas li ntawd, nws tag nrho Pitting Resistance Equivalent Number (PREN) muab nws ib qho kev tiv thaiv hnyav hauv zos pitting thiab crevice corrosion nyob rau hauv chloride- hnyav txheej txheem ntws.
Kev txo qis Media (Alloy C276 Advantage)
Alloy C276 zoo tshaj hauvtxo qis ib puag ncigua tsaug rau nws cov ntsiab lus siab molybdenum. Nws yog qhov kev xaiv tseem ceeb tshaj plaws hauv kev lag luam rau kev tuav cov tshuaj tiv thaiv hnyav xws li kub hydrochloric acid, sulfuric acid, thiab phosphoric acid. Nws kuj tseem muaj kev ntseeg tau tshwj xeeb tiv thaiv sulfide kev ntxhov siab tawg thiab cov roj qaub ib puag ncig hauv kev tshawb nrhiav roj.
Weldability thiab Thermal Stability
Thaum fabricating hnyav- cov txheej txheem phab ntsa, cov boilers muaj, los yog ua ntej -fabricated yeeb nkab spools, thermal stability yog qhov tseem ceeb.
Alloy C22yog engineered nrog optimized carbide stability. Nws tiv thaiv kev tsim ntawm cov nplej - ciam teb nag lossis daus hauv qhov kub ntawm qhov vuam - thaj chaw cuam tshuam (HAZ) zoo dua li ntau cov qauv qub. Cov cuab yeej no ua rau nws hloov tau yooj yim rau raws li -welded chemical nkoj sib dhos yam tsis muaj kev tshaj tawm tam sim ntawd -weld annealing.
Alloy C276muaj ib qho ultra-cov pa roj carbon tsawg thiab silicon los tiv thaiv kev weld-zone carbide nag lossis daus. Txawm li cas los xij, vim nws cov chemistry, ua tib zoo tswj xyuas cov khoom siv hluav taws xob thaum lub sij hawm vuam yuav tsum tau txo qis kom muaj kev cuam tshuam me me rau kub tawg lossis intergranular corrosion nyob rau hauv qhov chaw pabcuam hnyav heev.
Cov ntawv thov thiab kev lag luam siv
Alloy C22 Daim Ntawv Thov:
Cov chaw tsim tshuaj (thov kom huv-hauv- qhov chaw teeb tsa)
Flue gas desulfurization (FGD) scrubbers
Cellulose thiab ntawv pulp bleach nroj tsuag
Nuclear roj reprocessing thiab aggressive wastewater reclamation
Alloy C276 Daim Ntawv Thov:
Cov khoom siv Downhole rau cov roj qaub (H2S) oilfields
Cov txheej txheem tshuaj reactors tuav cov ntsiab lus siab ntawm cov chlorides kub
