QP5 Compliant Coating & Lining Inspection

TechCorr's QP5 Compliant Coating & Lining Inspection service provides independent, third-party verification that protective coating and lining systems are specified, applied, and verified in accordance with AMPP QP5 requirements and project specifications. As a QP5-certified inspection organization, TechCorr delivers the qualified personnel, documented procedures, and quality controls necessary to meet owner, regulatory, and warranty requirements.

The QP5 Standard

AMPP QP5 is the industry-recognized standard for coating and lining inspection companies. Certification requires verified inspector qualifications, documented quality procedures, and the organizational capability to deliver consistent, defensible inspection results. TechCorr's QP5 certification demonstrates that our processes, personnel, and reporting meet this rigorous standard.

What We Inspect

• Surface Preparation — Verification of cleanliness, profile, and surface conditions per SSPC-SP specifications and project requirements.
• Material Verification — Coating and lining product identification, batch control, and confirmation that materials match the approved specification.
• Application Monitoring — Environmental conditions, mixing ratios, application sequence, and wet-film thickness verification during application.
• Cure Verification — Dry-film thickness measurement, cure assessment, adhesion testing, and final visual acceptance inspection.
• Holiday & Continuity Testing — High- and low-voltage holiday testing to locate pinholes, voids, and discontinuities in lining systems.
• Lining Integrity — Inspection of tank, vessel, and pipe linings for holidays, thickness, and bonding to ensure long-term corrosion protection.

Documentation & Traceability

Every QP5 inspection is documented with detailed, traceable reports — including daily inspection logs, thickness readings, adhesion results, and deficiency records. These reports support project acceptance, warranty validation, and ongoing integrity management, giving owners a defensible record of compliance.

Applications

We support new construction, maintenance, and turnaround projects across storage tanks, pressure vessels, pipelines, structural steel, and marine assets — wherever coating and lining compliance is required.
