Q & A > Question Details
We are planning to carry out new Aux. HP steam Boiler hydrostatic test. Currently we do not have any demineralised or soften water available on site except with portable water via water tanker from desalination unit supply by contractor. (New Plant)
1) What type of chemical should be added to this water and in what concentration?
2) How do we dispose of the used water after hydro test?
3) After draining the boiler, how do we dry up the superheater tubes? Is using dry instrument (tool) air acceptable (no N2 easily available on site)?
