FAQ - Lub teeb Drawn ASTM B111 C68700 0.5mm Tube
Q1: Dab tsi yog MOQ rau C68700 0.5mm phab ntsa thickness raj?
A: MOQ rau C68700 0.5mm raj yog 500 kg.Rau cov qauv loj (OD 16-25mm, WT 0.5mm), GNEE lees txais kev txiav txim me me. Qhov loj me tshwj xeeb xav tau kev sib tham.
Q2: Qhov twg kim dua, ASTM B111 C68700 lossis C44300?
A: C68700 yog 10-15% kim dua C44300.C68700 muaj txhuas thiab arsenic, muab kev tiv thaiv zoo rau siab -ceev seawater impingement. C44300 muaj cov tin thiab haum rau qis dua - cov dej tsis huv. Kev xaiv nyob ntawm koj tus nqi ntws thiab dej zoo.
Q3: 0.5 hli phab ntsa C68700 lub raj tuaj yeem khoov?
A: Yog lawm. Qhov tsawg kawg nkaus khoov vojvoog yog 2 x OD.Ib txwm sivCov kua nplaum (O61)c68700 cev. Rau 0.5 hli nyias phab ntsa, siv lub mandrel thaum khoov kom tsis txhob muaj kev sib tsoo.
Q4: Dab tsi muab tub lim hlau pom zoo rau vuam C68700?
A: Siv ERCuAl-A1 (CuAl8) txhuas bronze muab tub lim.Welding method: TIG. Parameters: 80-120A, argon purity Ntau dua los yog sib npaug rau 99.99%, preheat rau 150 degree. Hla preheating thiab koj yuav raug arsenic porosity.
Q5: C68700 muaj pes tsawg xyoo nyob hauv dej hiav txwv?
A: Design life is >15 xyoo.Raws li ASTM G48, C68700 muaj qhov tob dezincification<200μm/year. Actual life depends on seawater temperature, flow velocity, and sand content. Condenser tubes typically last 15-20 years.
Q6: Qib dab tsi tuaj yeem hloov C68700 yog tias tsis muaj?
A: C70600 (90-10 tooj liab-nickel) yog kev hloov ncaj qha tab sis raug nqi 40% ntau dua.C70600 muaj kev tiv thaiv corrosion zoo dua tab sis tsuas yog 60% ntawm C68700 thermal conductivity. Rau kev khiav ceev<2m/s, consider C44300. For fresh water, use C12200.
Q7: Dab tsi yog qhov sib txawv hardness ntawm annealed thiab tawv temper C68700?
