DEMINERALIZED WATER
DEMINERALIZED WATER
(OP)
Question :
In conformity with ASME 1 Edition 2001, Addenda 2003, for a preheater in a Heat Recovery Steam Generator (HRSG), what kind of base metals (pipes and tubes) can be chosen with a view to face demineralized water (Oxygen = 5 ppm ) and a Temperature between 30 and 155 °C ?
P.S. Our first approach was to chose SA 249 T 304 and SA 312 P 304 which are not authorised by ASME 1 Code (see PG-5.5 and note 1 + PG 9.1)
Sincerely,
ATsampalas

As far heat exchanger tubing, there are typically no butt welds in the 304 ss tubing to be concerned about in service. The heat exchanger tubing is normally supplied as solution treated for maximum corrosion resistance.
