Supplemental buoyancy to offset mechanical shoe system
Supported by a system of buoyant pontoons — each pontoon is held in place by extruded structural aluminum framing for excellent strength and rigidity
Compression ring
The Retro-Fit Mini-Shoe employs a compression ring system to tie together the existing rim and Mini-Shoe hangers to form a strong and rigid perimeter structure that is strong enough to handle the weight, centering forces, and drag forces of a quality mechanical shoe seal.
Hardened-steel pressure components
Custom-hardened steel will not fatigue over time, maintaining proper sealing pressure against the tank shell and preventing gaps over the life of the seal.
Even pressure distribution
Each shoe is equipped with three sets of pusher bars, for a total of six pressure zones. This ensures even pressure distribution and allows the shoe to conform well to local anomalies in shell roundness.
Designed for tight rim spaces
The innovative feature of this seal is the HMT Mini-Shoe hanger assembly. It successfully maintains positive gap-sealing ability while accommodating rim spaces as small as 2.5 inches.
Best-in-class vapor barriers
Premium fabric options ensure optimal product compatibility and life span, even including flame-retardant PTFE options compliant with DIN 22118 standard.
Sized to fit the tank
All tank shells are not alike, and it’s critical that seals are designed to handle unique rim-space requirements. HMT’s engineering and manufacturing automation allow each seal to be manufactured to fit the specific rim-space and/or verticality data provided by the purchaser, ensuring optimal performance and mitigating the chance of operational issues over time.
