Scope of Work
Protection of new impeller and casing, designed for use in aggressive conditions.
Internals: Corroglass 600 Series.
Externals: Plasmet ZF.
• Internal: The impeller was grit blasted to ISO 8501-1, SA 21/2and treated using Corroglass 600 Series materials.
• The casing was grit blasted internally to the same standard, followed by application of Corroglass 600 Series to a minimum dry film thickness of 1mm, carried into the flange rebates and finished flat to ensure optimum performance in use
• External: The area was grit blasted to SA 2 and protected using two coats of Plasmet ZF.
This particular unit was developed for use at a duty incorporating 1% hydrochloric acid, 500ppm monochlorobenzene and moist air at 30ºC, operating at a maximum of 1339rpm and requiring additional protection against corrosion attack.
Using Corrocoat’s Engineering facilities the impeller was fully balanced to BS6861-pt1.
