FAQ
Q1: Dab tsi yog qhov txawv ntawm C12200 thiab cov raj tooj liab tsis tu ncua?
A: C12200 muaj ib qho me me ntawm phosphorus (0.015-0.040%) uas ua raws li deoxidizer. Lub raj tooj liab tsis tu ncua (xws li C11000) tsis muaj phosphorus thiab tuaj yeem raug kev txom nyem los ntawm hydrogen embrittlement thaum welded. C12200 tshwj xeeb yog tsim los rau kev siv vuam thiab kub exchanger.
Q2: C12200 puas tuaj yeem siv rau hauv dej hiav txwv?
A: Tsis yog C12200 tsis pom zoo rau kev pabcuam dej hiav txwv. Nws muaj kev tiv thaiv zoo rau cov dej tshiab tab sis yuav corrode hauv dej hiav txwv. Rau cov ntawv thov dej hiav txwv, xav txog C70600 (90/10 tooj liab-nickel) lossis C71500 (70/30 tooj liab-nickel).
Q3: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau C12200 raj?
A: C12200 tuaj yeem ua haujlwm tsis tu ncua txog li 200℃(400℃F). Tshaj qhov kub no, lub zog txo qis heev. Rau kev siv kub dua, lwm yam alloys yuav tsum xav txog.
Q4: Yuav ua li cas khoov C12200 tooj liab raj?
A: Siv annealed temper (O61). Qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yog feem ntau 2.5 × OD rau annealed raj. Mandrel dabtsi yog khoov yog pom zoo rau nruj radii. Hard drawn tube yuav tsum tsis txhob khoov yam tsis muaj annealing ua ntej.
Q5: Yuav ua li cas rau vuam C12200 tooj liab raj?
