Retro PMI (Positive Material Inspections)
An inspection system adapted to perform retro positive material identification of components of a multi-feature system while at the same time minimizing the amount of insulation needed to be removed.
Application:
- Identify systems to be inspected
- Identify number of piping spools per drawing
- Identify number of components (nipples,fittings,valves,etc..)per drawing
- Identify number of piping spools and components (nipples,fittings,valves,etc..)per drawing to be Inspected
- Enter all points into tracking spreadsheet
- Strip insulation at known components and scaffold as needed
- Prepare surface for PMI
- Take surface temp. readings and record
- Take PMI readings at designated locations and record
- Use Weld detection tool at stripped areas to locate any unknown welds
- Strip areas found using weld detection tool and take appropriate PMI readings(if any found)
- Document all findings on report format and tracking spreadsheet
- NDT TOOLS USED:
- EMAT Weld detection AXIAL tool HIGH Temp (HT-2200)
- INNOV-X Alpha 2000 PMI Instrument
- Cordless Drill with appropriate grinding stone (surface prep)
