Coating inspection

FROSIO Level III inspection of protective coatings, from blast cleaning to final release. Every hold point is measured, recorded and reported against the coating specification.

  • Surface cleanliness, profile, soluble salts and dust
  • Climate monitoring: steel and air temperature, humidity, dew point
  • Wet and dry film thickness
  • Pull-off and cross-cut adhesion, holiday detection
  • FBE, polyurethane, zinc and field joint coating systems
  • Daily inspection reports, NCRs and the final coating dossier

ISO 8501, ISO 8502, ISO 8503, NACE SP0188, ISO 21809

  • Visual inspection of welds (VT2, ISO 9712)
  • Penetrant (PT), magnetic particle (MT) and ultrasonic (UT) testing, level 2
  • WPS and PQR review against the project specification
  • Review of NDT reports and heat treatment records
  • Pressure vessels, shell and tube heat exchangers, valves, pipe spools, structures

Forged rings coming out of heat treatment

Forgings, materials and mechanical testing

Inspection at forges, foundries and machine shops, from the furnace to the test lab, so the material certificate matches what was actually made.

  • Heat treatment witnessing and temperature checks
  • Brinell hardness testing
  • Tensile and Charpy impact test witnessing
  • Ultrasonic testing of forgings and bars
  • Dimensional inspection of forgings, shafts, studs and bolts
  • Positive material identification (PMI) of alloys
  • Marking, traceability and MTC verification

Supplier quality surveillance

RINA trained in SQS for the equipment that most often holds up a project. Regular visits to the vendor, early warning on quality and schedule risks, and reports the client can act on.

  • Valves
  • Pressure vessels
  • Shop fabricated piping
  • Shell and tube heat exchangers
  • Supplier quality audits

RINA SQS004, 006, 007, 008, 010

Technical consultancy

Support before the work starts, so that inspection finds fewer problems later.

  • Writing and reviewing inspection and test plans (ITP)
  • Coating specifications and anti-corrosion advice to NACE/AMPP and ISO 21809
  • WPS and PQR evaluation
  • Quality documentation and final QC dossiers

How an inspection runs

  1. RequestYou send the scope, location, dates and specification.
  2. ReviewSpecification and ITP reviewed, hold and witness points agreed.
  3. EquipmentCalibrated instruments checked and certificates ready.
  4. InspectionWork inspected on site or in the vendor’s shop.
  5. ReportFindings recorded with measurements and photographs. Non-conformities raised as NCRs.
  6. ReleaseRelease note signed and documents handed over for the dossier.
