COATING INSPECTION SERVICES
AMPP Level 2 certified coating inspection for pipelines, pressure vessels, storage tanks, and structural steel. Surface preparation verification, DFT measurement, holiday testing, and full coating QA documentation in Edmonton and across Alberta.
Industrial Protective Coating Inspection
Protective coatings are a primary corrosion control method for above-ground and buried assets throughout Alberta's oil and gas, petrochemical, and refining industries. The performance of a coating system depends almost entirely on the quality of surface preparation and application - making independent coating inspection critical to achieving service life.
AMPP (formerly NACE International) Level 2 Coating Inspector certification is the widely recognized qualification standard for industrial coating inspection. Level 2 inspectors are trained and tested on surface preparation standards, coating application inspection, test methods, and inspection documentation for industrial environments.
Coating inspection scope ranges from external pipeline coating and structural steel painting to internal lining inspection for storage tanks and pressure vessels. Each application has distinct methods, acceptance criteria, and documentation requirements specified by owner standards, project specifications, and applicable codes including NACE, SSPC, and ISO standards.
What's Included
- -Surface preparation inspection per SSPC and NACE standards: surface profile measurement and cleanliness verification
- -Ambient condition monitoring: temperature, humidity, dew point, and surface temperature logging before and during application
- -Wet film thickness (WFT) measurement during application to verify DFT compliance
- -Dry film thickness (DFT) measurement per SSPC-PA 2 using calibrated gauges
- -Holiday (discontinuity) testing per NACE SP0188 using low- and high-voltage detection
- -Adhesion testing per ASTM D4541 pull-off method
- -Internal lining inspection for storage tanks: floor, shell, roof, and nozzle internals
- -External pipeline coating inspection: FBE, 3LPE, coal tar enamel, and tape wrap condition assessment
- -Coating inspection reports with pass/fail documentation, photo records, and non-conformance tracking
- -Coating system review and specification check against applicable standards and owner specifications
Coating Inspection Scope Areas
Pipeline External Coating
FBE, 3LPE, coal tar enamel, and tape wrap inspection. Pre-application surface preparation, application witness, and holiday detection. Critical for pipeline corrosion control programs.
Storage Tank Internal Lining
Internal lining inspection during API 653 turnarounds. Existing lining condition assessment, surface prep witness, application inspection, DFT, and holiday testing before return to service.
Pressure Vessel Internal Lining
Vessel lining inspection for ASME vessels in corrosive service. Lining condition assessment, surface preparation verification, coating application witness, and post-application testing.
Structural Steel & Facilities
Shop and field painting inspection for structural steel, process piping, and facility equipment. Surface preparation, DFT, and documentation per owner specifications and SSPC/NACE standards.
FAQ
What is AMPP Level 2 Coating Inspector certification?
AMPP (Association for Materials Protection and Performance, formerly NACE International) offers a tiered coating inspector certification program. Level 2 Coating Inspector certification demonstrates competency in surface preparation inspection, coating application inspection, testing methods including DFT measurement and holiday detection, and inspection documentation. It is widely specified by owners and EPC contractors as the minimum qualification for coating inspectors on industrial projects in oil and gas and petrochemical industries.
What surface preparation standards apply to industrial coating work in Alberta?
SSPC (Society for Protective Coatings) surface preparation standards are the primary reference in Alberta industrial coating work. SSPC-SP 6 Commercial Blast, SSPC-SP 10 Near-White Blast, and SSPC-SP 5 White Metal Blast are commonly specified depending on service environment and coating system. ISO 8501-1 blast cleanliness grades are also referenced on international projects and by some owner specifications. Surface profile is typically specified per SSPC-PA 17 or equivalent and measured with Testex Press-O-Film tape.
Is internal lining inspection different from external coating inspection?
The fundamental test methods are similar but the access, application conditions, and acceptance criteria differ significantly. Internal lining inspection for storage tanks is conducted inside confined spaces under controlled conditions. DFT requirements for internal linings are often higher, chemical resistance requirements drive system selection, and holiday testing voltage is specified based on the lining system thickness. For tanks storing corrosive products, internal lining integrity is a critical factor in API 653 fitness-for-service assessment.
Can coating inspection be provided during turnarounds in Alberta?
Yes. Turnaround coating inspection is a common service scope. During plant turnarounds, coating inspection typically covers internal inspection of vessels and tanks following decontamination and entry, assessment of existing lining condition, witness of surface preparation and recoating, and DFT and holiday testing of new lining application before the asset is returned to service. Turnaround coating inspection is closely coordinated with API 510 and API 653 inspection activities.
