Evidence-first editorial standard
This guide separates observed facts, engineering assumptions and data that still require confirmation. It does not promise a universal service life or replace the exact product data and project specification.
Define the inspection plan before installation begins
The drawing, lining schedule, exact materials, approved product data, surface-preparation method, attachment procedure, environmental limits, acceptance criteria and responsible parties should be available at the workface. Mark mandatory hold points. A checklist cannot replace the project specification, but it can make omissions visible before they are covered.
Accept the substrate before lining it
Verify that structural or pressure repairs are complete, dimensions and geometry match the drawing, welds and edges are suitable, and corrosion, grease, salts, dust and old lining have been addressed. Record surface condition and environmental readings required by the named attachment system. Do not hide cracks, distortion, active contamination or unsupported voids beneath ceramic.
Check materials, identity and storage
Confirm ceramic grade and format, dimensions, quantity, batch or traceability information where specified, adhesive or grout identity, shelf life, storage condition and compatibility of primers, fillers and retention hardware. Segregate damaged or contaminated pieces. Product substitution requires a documented technical review rather than a visual similarity judgment.
Inspect layout, support, joints and attachment during the work
Confirm orientation against material flow, full support, joint pattern, edge protection, transitions, penetrations, terminations and access for future repair. Check adhesive mixing and application against the approved procedure, and verify mechanical or weldable retention where specified. Photographs should show areas that will become inaccessible.
Control cure, completion and handover
Protect the installed lining from movement, moisture, contamination and premature service for the conditions stated by the exact system. Inspect for loose pieces, rocking, open joints, exposed adhesive or steel, sharp internal steps and unfinished edges. Record repairs, deviations, as-built layout, material batches, environmental checks and the release decision.
Establish an in-service baseline
Keep overview photographs and close views of high-risk zones, mark reference locations and record operating hours or throughput from commissioning. Early follow-up should look for new cracks, joint recession, tile movement, edge attack, corrosion staining and changes in flow path. Inspection frequency must follow risk, access and observed condition rather than a universal calendar.
Treat nonconformities as evidence, not cosmetic defects
Record location, extent, probable consequence and disposition, then identify who accepted repair, use-as-is or replacement. If a defect can expose neighbouring edges, steel, adhesive or pressure boundary, review the wider zone. A useful inspection record allows the next outage team to compare change over time and understand why each decision was made.
