Storagetech seal systems are designed to prevent product loss and atmospheric contamination from Aboveground Storage Tanks as well as provide a weather shield. Our seal systems meet or exceed environmental regulations and are custom designed to ensure effective operation in specific tank conditions. Storagetech Seal Systems can be installed while the tank is in-service. It is easy to install and has no need for a special tool.
API test programs for evaporative loss and emission show that emissions from roof (deck) fittings without seals or gaskets can be a significant portion of the total emissions from ASTs. A well-designed and maintained peripheral rim seal may not always keep the tank in compliance. Wind factors can increase VOC emissions, particularly from roof fittings that are not properly sealed.
Storagetech seal systems are engineered, tested, and manufactured to meet EPA-AST Environmental Compliance requirements. Different types of seals & combinations are available to suit pontoon & double deck external floating roof tanks & fixed roof tanks with pan deck roofs or aluminum decks.
