Aluminum Floating Roof Seals
Primary Shoe Seals
The patented ALLENTECH stainless steel mechanical shoe with its Teflon vapor barrier is the only shoe seal specifically designed for aluminum internal floating roofs. It offers a 20-year design life and excellent overall performance because of its resistance to most chemical products and ability to stand up to extreme temperature variations. Tightly spaced hoop springs exert a nearly constant force against the tank shell to maintain the seal even around peaked vertical seams and abrupt tank distortions. In fact, capacity loss is reduced by 6" with the ALLENTECH shoe when compared to a double wiper seal.
ALLENTECH's shoe seals can be retro-fitted on most existing aluminum internal floating roofs.
ALLENTECH's primary shoe seal meets current U.S. Environmental Protection Agency requirements without a secondary seal but is available with an independent secondary shoe or wiper seal.
