Long term protection against corrosion for fire mains reducing piece
Scope Of Work
Protection required from sea water for reducing piece
forming part of a fire mains system. Without
protection, severe corrosion would occur rapidly in this
aggressive sea water environment.
Corroglass 600 series.
Grit blast internally and externally to ISO 8501-1 SA 21/2.
Corroglass 600 series applied internally to a minimum
dft of 1.5mm, carried through into flange rebates and
finished flat. 100% spark tested and thickness checked.
Two coats of Plasmet ZF applied externally Top gloss
coat of Corrothane AP1 (color green 14 e 53 to
Protecting this component using Corroglass will give
outstanding long term performance, with exceptional
resistance to solvent and sea water attack.
Corroglass is a high build glass flake vinyl ester resin.
The reducing piece will now meet the 15-year life
expectancy specified by the customer. This far exceeds
the capabilities of most other coated or uncoated
components used in such aggressive environments.
