Txhuas tooj dag raj - C68700 -
Inhibited Aluminium Brass tubes - C68700 - tawm tsam kev ua haujlwm ntawm cov ntsev nrawm thiab cov dej dub thiab feem ntau siv rau cov raj dej condenser. Tus yam ntxwv tseem ceeb ntawm C68700 yog nws qhov kev tawm tsam siab rau qhov cuam tshuam nres. Cov hlab ntawm cov alloys tau pom zoo siv rau hauv Marine thiab Land Power Stations, nyob rau hauv cov dej txias ua kom dej siab.
