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 and pusher plates, for a total of ten pressure zones. This ensures even pressure distribution and allows the shoe to conform well to local anomalies in shell roundness.
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 is 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.
Remains level as rim space varies
Each shoe expands and contracts at the same level regardless of local rim-space variations. This ensures no “shoe drop” in wider rim spaces (which could lead to gapping issues at shoe joints).
Handles a wide range of rim spaces
The HMT Scissor Shoe Seal handles rim spaces from 3.5 to 18 inches and can be customized to handle up to 24-inch rim spaces.
