scope:

The material in this Standard has been selected to incorporate the safest available design criteria, as well as the highest levels of deaerator performance.

This Standard reflects the collective knowledge and experience of the Deaerator Technical Committee, and is reviewed and discussed during regularly scheduled meetings. This process insures that the Standard will be regularly updated to reflect the changes in technology, codes, and member experience. This Standard continues to be influenced by the work of other organizations, such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Society for Testing Materials (ASTM), NACE International, The Corrosion Society, and the Technical Association of the Pulp and Paper Industry. Special consideration and credit is given to NACE and TAPPI, for their extensive research on deaerator pressure vessel cracking. Particular attention and credit is given to NACE Standard RPO 590-90. Adherence to this Standard is strongly recommended. Comments and suggestions for the improvement of this Standard are always welcome and should be directed in writing to the Deaerator Section at the Institute's address.
