Design intent
The system, in one paragraph.
FirePermaFuse is an FM Global- and UL-listed bolted fire-protection reservoir sized for NFPA 22 static fire reserve — the tank that has to work on the one day of the decade the building burns. Because the interior coating is a fired glass and not a solvent-borne paint film, nothing on the wet side can blister, mud-crack, or shed particulate into the pump suction. Factory pre-piped sidewall flanges match common Viking, Victaulic, and ANSI inlet and anti-vortex geometries; seismic anchor chairs are stamped to the installing jurisdiction. Lead time to a filled, commissioned, FM-witnessed reservoir is one quarter of a welded steel equivalent.
Specification
Governing values.
Published specifications reflect the base fused-envelope configuration. Application-specific deviations — nozzle pattern, gasket compound, coating color — are documented in the commissioning binder signed at hydrotest.

Coating service life is warranted — not estimated. No recoats, no refurbishment, no scheduled interior paint. The glass that leaves our furnace is the glass that retires with the tank.
