Condition assessment on power and steam plant

A comprehensive condition assessment of power-generating and steam-raising plant at a steel works in South Korea has been completed by AEAT Sonomatic Field Services. The project was carried out on behalf of Pohang Steel Company, who needed to establish the condition of its 20- year old plant before commencing a refurbishment and renewal programme.

The plant comprised the steam boiler and associated pipework, a steam turbine, a compressor and a generator. Sonomatic engineers first spent four weeks defining the scope of work, before carrying out the assessment over a four month period. This involved two technicians working on site with local labour to gather data and then transmitting this data to Risley in the UK for off-line analysis.

A wide range of assessment techniques was applied, including manual ultrasonic inspection, magnetic particle inspection and dye penetrant inspection to establish the degree of any corrosion damage. Creep damage was investigated by replication measurement, while international computer codes were applied to assess turbine condition.

All the data collected was analysed with respect to accepted codes to allow predictions to be made on the life expectancy of the various elements of the plant.
