Overview
The HMT SM1 Heavy Duty Shoe Plate Rim Seal is a liquid mounted primary shoe plate seal with a shoe mounted secondary seal. This robust seal is specially designed for arctic heavy snow load conditions. The scissor mechanism is designed and tested for a snow load of 10KN/m2.
Key Benefits
The SM1 Seal’s primary benefits include:
Complete product compatibility— all construction materials are selected to be compatible with the stored product.
Worry-free operation — centers the floating roof and dampens horizontal roof movement.
Designed to remain in contact with the tank at all times — the R(-X/+3X) design working range feature is a TankSystems innovation. Under all circumstances the SM1 seal will stay in contact with the tank shell.
Flame retardant and UV resistant seal— materials on the seal are flame retardant in accordance with DIN 22100/22188. Additionally, materials subject to the atmosphere are UV resistant.
Gas tight seal — with the shoe plate overlap membrane thermally welded to the primary seal membrane, this seal is gas tight.
