PRT has the experience and time-tested technical experts to provide your company with “value added” information and lasting solutions to your problems through condition assessment.

Level I inspection

A plan is prepared after a thorough review of the plant’s operations (both current and historical). Level I Condition Assessment involves detailed visual inspection techniques, simple NDE methods (MT, PT, UTT) and measurement tools to determine if more detailed analysis is required. The components generally inspected are:

  • Boiler structure and supports
  • Burners
  • Critical planning
  • Down-comers
  • Flues and ducts
  • Headers
  • Water-walls
  • Steam drums

 

Level II condition assessment

Based on the findings observed during a Level I inspection, more advanced NDE techniques and sampling are utilized, which include:

  • Advanced UT (PAUT)
  • Hardness / PMI
  • High temperature strain gages
  • Metallurgical and Oxide analysis of tube samples
  • Remote visual inspection
  • Surface replications
  • UT–oxide thickness
  • WFMT
