Construction & operation
A foam pourer delivers expanded foam onto the rim seal area of a floating roof tank — the annular space between the tank shell and a foam dam on the roof. It is mounted on the shell near the top, fed by a foam maker or a foam solution line, and its deflector turns the foam down the inside of the shell so it settles into the seal area rather than onto the roof.
Maintenance
- Inspect the outlet and deflector for corrosion and blockage.
- Check the foam dam on the roof is intact — the pourer relies on it to hold the foam over the seal.
- Test at the intervals the governing code sets.
