Kev Yuav Qhia: F51 duplex steel feem ntau xaiv thaum 316 stainless hlau tsis ua haujlwm vim chloride corrosion lossis kev ntxhov siab tawg.
Yuav ua li cas kom tsis txhob vuam tsis ua hauj lwm?
Vuam txoj kev: GTAW (TIG) - nyiam rau precision piping; SMAW - tshav welding; FCAW - txwv kev siv
F51 yuav tsum tau welded nrog ER2209 muab tub lim hlau. Khaws cov khoom siv hluav taws xob ntawm 0.5–1.5 kJ / mm los tiv thaiv kev tsim cov nkig intermetallic theem (sigma theem) hauv tshav kub- thaj chaw cuam tshuam (HAZ).
Weld Failures Case:
| Qhov teeb meem | Ua rau | Kev daws |
| Sigma theem tsim | Kub kub | Tswj interpass temp (<150°C) |
| Poob ntawm corrosion kuj | Tsis tsim nyog muab tub lim | Siv ER2209 nkaus xwb |
| Kub tawg | High tshav kub input | Txo cov cua kub nkag |
| Ferrite imbalance | Cov cua txias tsis zoo | Tswj cua txias |
Cov teeb meem hauv teb
- "316L fittings ua tsis tiav hauv seawater txias loops hauv 18 lub hlis"
- "Tshuaj galling pom nyob rau hauv stainless couplings thaum kho"
- "Weld discoloration ua rau ntxov corrosion nyob rau hauv duplex piping"
Engineering Lessons
- Duplex fittings feem ntau nyob rau hauv - qhia hauv kev yuav khoom (tus nqi - hloov pauv nrog 316L ua rau tsis ua haujlwm)
- Threaded couplings xav tau los tiv thaiv -galling lubrication
- Welding txheej txheem tsim nyog (WPS/PQR) yog qhov tseem ceeb, tsis yog xaiv tau
- Material traceability (PMI testing) yog qhov tseem ceeb rau kev tshawb xyuas offshore

FAQ:
Q: Dab tsi yog ASTM A182 F51 coupling nqi hauv 2026?
A: Tus nqi feem ntau yog li ntawm $ 3.8- $ 8.5 / kg nyob ntawm qhov loj me, qhov ntsuas siab, thiab cov txheej txheem tsim khoom.
Q: Qhov txawv ntawm ib nrab coupling thiab tag nrho coupling yog dab tsi?
A: Ib nrab coupling yog welded ntawm ib sab ntawm cov yeeb nkab, thaum tag nrho coupling txuas ob lub kav dej rau inline txuas ntxiv.
Q: Puas yog F51 zoo dua li 316 stainless hlau?
A: Yog, F51 muaj cov tshuaj chloride ntau dua, lub zog, thiab kev pab lub neej ntev dua hauv dej hiav txwv thiab ntug dej hiav txwv.
Q: Qhov twg yog ASTM A182 F51 nquag siv?
A: Nws yog siv rau hauv cov roj & roj, cov nroj tsuag desalination, chemical processing, thiab marine engineering systems.
Q: Vim li cas duplex steel nqi ntau dua carbon steel?
