Cov qhab nia xaiv tau
- C44300 (Naval Brass): Muab cov nqi zoo- ua haujlwm tau zoo thiab tsim nyog rau thaj chaw dej hiav txwv ntawm qhov hnyav hnyav; Txawm li cas los xij, nws tsis kam mus rau siab - nrawm yaig yog qhov tsis muaj zog.
- C70600 (90/10 Copper-Nickel Alloy): Muaj kev tiv thaiv zoo rau marine corrosion; nws yog cov khoom siv zoo tshaj plaws rau cov dej hiav txwv corrosive heev, txawm hais tias nws cov khoom siv yog tus nqi siab.
- C71500 (70/30 Copper-Nickel Alloy): Zoo tshaj plaws rau cov huab cua hauv hiav txwv thiab siab - qhov kub thiab txias, tab sis nws kim heev.
- 316L Stainless Hlau: Pom zoo tag nrho corrosion kuj; Txawm li cas los xij, nws cov thermal conductivity tsawg ua rau muaj kev hloov pauv hluav taws xob tsawg hauv cov ntawv thov condenser.
thaj chaw thov
ASTM B111 C68700 Aluminium Brass U- cov raj yog tsim los rau kev hloov pauv kub thiab kev tiv thaiv corrosion, ua rau lawv tsim nyog rau kev xav tau qhov chaw txias txias -tshwj xeeb yog cov dej hiav txwv lossis cov xov xwm txias heev. Cov ntawv thov ib txwm muaj xws li:
- Kev lag luam tsim hluav taws xob: Nto condensers hauv thermal fais fab nroj tsuag, chav turbine tso condensation systems, thiab lwm yam.
- Marine & Offshore Engineering: Onboard condenser systems thiab tshav kub exchangers.
- Petrochemical & Industrial Processing: Condensers thiab evaporators hauv cov nroj tsuag tshuaj, cua txias hauv cov chiv thiab cov chaw tsim khoom ammonia, thiab lwm yam.

FAQ
Q: Qhov txawv ntawm C68700 thiab stainless hlau yog dab tsi?
A: C68700 muaj ntau dua thermal conductivity thiab superior tiv thaiv fouling.
Q: Puas yog C68700 txhuas tooj dag raj tsim nyog siv rau hauv dej hiav txwv nrog cov xuab zeb siab?
A: Tsis yog, nws tsis pom zoo. Thaum C68700 nthuav tawm kev yaig zoo heev hauv dej hiav txwv huv, cov xuab zeb siab ua rau cov xuab zeb ua rau abrade cov yeeb yaj kiab oxide tiv thaiv, yog li ua kom nrawm dua corrosion. Rau cov ntawv thov txias uas muaj cov xuab zeb seawater, nws raug nquahu kom xaiv C70600 lossis C71500 alloy tubes hloov.
Q: C68700 puas tuaj yeem welded?
A: Yog, lawv tuaj yeem ua tau. C68700 yog tsim rau ntau yam vuam txheej txheem, suav nrog brazing, roj vuam, tsis kam vuam, thiab roj- shielded arc vuam; Txawm li cas los xij, electroslag vuam thiab submerged arc vuam tsis pom zoo.
Cim npe nrov: c68700 txhuas tooj dag raj, Tuam Tshoj, lwm tus neeg, manufacturers, hoobkas, customized, lag luam wholesale, nqe, OEM, zeb, tsim, kev muag khoom
