					Note
1.일반적인 Engineering Practice로는 Duplex SS Material을 HCL에 사용하는 않습니다.
2.염산은 Boiling Point가 농도에 따라 약 90C ~ 110C사이입니다.
  120C이상인 경우 Vapor가 되는대, Operating Temp.가 120C가 맞는지 확인 필요합니다.
3.적절한 Material 선정을 위하여서는 정확한 Operating Temp. Phase, Concentration, Aeration 여부,
  Oxidizing Agents 여부 등을 알아야 합니다.
4.낮은 온도의 3%이하로 Concentrated된 HCL용으로 Duplex를 사용할 수도 있으나, Service특성을 면밀히
 검토하여야 합니다.
5.Boiling Point이하에서, 추천되는 Material은 Hastelloy-B, Monel, Glass Lined 등입니다.
6.Acid중에서는 염산이 Corrosion등의 문제로 가장 Handling하기 어려운 Service입니다.
  Basic사나, Client의 승인이 없이 Duplex를 염산 Line에 사용하지 마시기 바랍니다.
7.첨부된 Class는 참조용으로 작성한 Duplex Piping Material Class입니다.
ation, Aeration 여부,

나, Service특성을 면밀히
