What are NACE Coating Inspections?

Purpose:

• To ensure that protective coatings are applied correctly.
• To verify that coatings meet the required standards.
• To prevent corrosion and extend the life of structures and equipment.

Inspector’s Role:

• A NACE-certified inspector checks the coating process from start to finish.
• They use various tools and methods to assess the quality and effectiveness of the coating.

Coating Inspections are Important

• Preventing Corrosion: Properly applied coatings protect metal structures from rust and decay.
• Safety: Ensures that structures, such as bridges, pipelines, and tanks, remain safe and functional.
• Cost Savings: Reduces the need for expensive repairs or replacements due to corrosion damage.
• Compliance: Helps companies meet industry standards and regulations.

Key Steps in NACE Coating Inspections

Surface Preparation Inspection:

• Before applying the coating, the surface must be properly cleaned and prepared. This might involve removing rust, old paint, or other contaminants.
• Inspectors check the cleanliness and profile (texture) of the surface.

Environmental Conditions:

• Inspectors measure temperature, humidity, and dew point to ensure conditions are suitable for coating application.

Coating Application:

• They monitor the application process, ensuring the correct thickness and evenness of the coating.
• This involves checking for uniform coverage without bubbles, blisters, or other defects.

Curing and Drying:

• Inspectors verify that the coating is allowed to cure (harden) properly, which is crucial for its protective properties.

• After the coating has cured, a final inspection ensures that the coating meets all specified standards.
