Category A |
Abrasive blast cleaning |
|
|
Standard: Sa2½
Surface profile: 50-75 microns |
| |
|
|
Category B |
Fresh water wash down followed by a thorough hand/power tool cleaning |
| |
|
Standard: St2 |
| |
|
|
|
Category C |
Fresh Water wash down, heavy chipping hammers to remove heavy rust, thorough |
| |
|
hand wire brushing to remove all loose scale and old coatings(conditions where St2 mechanical cleaning is not fully achievable due to condensation, deep pitting etc). |
| |
|
|
| |
