Coatings and insulations are amongst the most critical components to overall asset integrity. Visual inspection, holiday testing, surface preparation, bonding, application, repairs, and recommendations under the supervision of qualified QA/QC personnel are essential to the success of the applied coating.
Certification Requirements:
- NACE level 1, 2, 3 for inspection & applications.
- Coating application experience.
- Media Blast for removals.
- Irata level 1, and 2, with 3.
Coating Applications:
Rope access is an effective method to do coating repairs and replacements in tight windows.
Coating Inspection:
Visual inspection is the most effective method to inspect coatings. This should be reinforced with holiday testing, thickness measurements (DFT/WFT), environmental controls, proper surface conditions, and QA/QC during the application and inspection periods.
Coating Inspection and Application Results:
- Application in accordance with governing standards.
- Adequate surface preparation.
- Maximized coating life.
- Repairs to achieve intended service cycles.
Insulation Inspection:
Corrosion under insulation can have a detrimental effect on equipment.
Inspection Planning Checklist:
| Asset Component | Required Action |
|---|---|
| Type of Coating | Verify through company records, nameplate data and drawings. |
| Dry Film Thickness | Measured with a coating thickness gauge. |
| Wet Film Thickness | Wet film thickness gauge. |
| Visual Defects | Verify with flashlight and magnification as required. Ensure sufficient cleaning. |
| # of Holidays | Examination performed with low or high voltage holiday detection tool at a voltage determined by coating type and thickness. |
| Application Errors | Check for runs, uneven thickness, fisheyes, lack of adhesion, poor work practices. |
| Remaining Life | Verify application date and intended life cycle with service, and as found field results. |
| Insulation Cladding | Check for structural integrity, holes, other damages. |
| Insulation Material | Verify if CUI is present, and the overall condition of insulation material. |
| Banding | Check for tightness and damage. |
| Fasteners | Verify the condition of fasteners. |
| Hardware | Verify if all hardware is present and operating. |
