Coating inspection is one of the processes that helps to preserve and enhance the working lifespan of equipment and structures in the industry and infrastructure maintenance. No matter whether working with pipelines, tanks, or bridges, knowing the coating inspection methods and practices can help in the proper execution of the projects. The most advanced organizations in this regard are NACE International, now part of AMPP (Association for Materials Protection and Performance).
What is NACE/AMPP?
NACE International, a member of AMPP currently, is an international society that aims towards the progress of corrosion and protection coating technologies. Members of AMPP take pride in the achievements of NACE and SSPC: their finest insights and best practices have been systematically compiled into standardized, well-structured regimes for certification and licensing of industry professionals.
Why is Coating Inspection Important?
In this regard, coating systems are meant to provide a form of barrier to the structures against environmental attack, corrosion, and to some extent wear. Inspections of this type ensure that when coatings are put on, the right procedures have been followed and will preserve their protective characteristics. If there is no inspection or an effective and efficient program to incorporate inspection, coatings may fail early, resulting in expensive repairs and possible safety Hazards.
Key NACE/AMPP Certification Levels
NACE/AMPP CIP Level 1: Basic Coatings Inspector
NACE/AMPP CIP Level 2: Certified Coatings Inspector
NACE/AMPP CIP Level 3: Senior Certified Coatings Inspector
The following are the most common steps for Coating and Inspection:
· Review Project Specification.
· Necessary Safety Precautions.
· Inspection Test Plan.
· Surface Preparation followed by inspection.
· Monitoring of environmental conditions like Temperature, Humidity, and dew point.
· Coating application inspection such as; Verify coating type and mixing, and application technique ( spraying, brushing, rolling).
· Dry Film thickness (DFT) check
· Any additional testing like pull test/Adhesion testing if required.
· Final inspection, and preparation of records/documents.
