3.0 Finish (Back to Top)

3.1 Internal Internal Shell Surface Shot blasted to SA 2½
Weld Seams As welded
3.2 External External Surface Shot blasted to SA 2½ prior to painting
Weld Seams As welded

3.3 Fittings
   All fittings, including valves and pipe sections shall be degreased and then stored in clean sealed plastic bags until fitted to the tank.

3.4 Cleaning
   After shot blasting, the vessel's internal surface is vacuum cleaned with an industrial vacuum machine. After cleaning, the opening points are sealed ready for leak test and nitrogen purging.

3.5 Leak Test and Nitrogen Purge
   After cleaning, all valves, blind flanges, caps, and connected piping are installed and a leak test is performed at 4 bar using Nitrogen. The vessel will be delivered in a Nitrogen purged condition. Dry nitrogen will be used (O2 < 1% residual oxygen, at 2.0 bar pressure, with nitrogen dew point -20°C).

3.6 Painting (Hempel Coatings)
   The carbon steel frame components are shot blasted to SA 2½ and painted as follows:
