ON NEWLY FABRICATED VESSELS
Vessel TAG Numbers
Our first inspection inside the vessel is to identify any sharp edges that need grinding or radiussing
And mark them up
We have achieved our 75 microns but we have a problem the most common problem that occurs after the blasting is water coming out of a porous weld after the hydrostatic pressure test
What do we do ?
Have we done a dust check and have we achieved the method statements requirement
If not achieved re-vacuum and check again
Have we done a salt check and have we achieved the method statements requirement
If we have not achieved wash the surface and re-blast

FROST BLAST

BRUSH BLAST
4 common terms used to describe a lightly grit blasted surface on the Belzona coating
The aim of the frost blast is to remove the surface gloss (shine/sheen) from the cured Belzona coating system to a frosted appearance (the same way that glass would have an etched / whitish “frosted” appearance if sand blasted) with a surface profile of around 25 microns. For the purpose of this frost blasting we recommend using a finer grit.The method we would use would be:-1. Blast nozzle pressure 50 to 80 psi 2. Abrasive grade 60/303. Recommended Abrasive type - Garnet4. Distance of nozzle from surface 400 - 500mm5. Nozzle type – 8 to 12mm diameter venturi type6. Blasting angle to surface - 45 degreesThe aim of this blasting procedure is also intended to remove any contaminants from the surface. It is not to produce a profile similar to that required on bare steel. The frost blasting of the relatively soft Belzona material will automatically produce a fine profile, giving the clean surface a satin or frosted appearance.With inexperienced operators, a test section should be evaluated before and after blasting.
