Boots/Bellows Designed for Power Plants, Refineries & Chemical Plants
Gortiseal™ piping penetration seals are designed to provide a flexible and safe method of sealing process piping. The primary applications for Gortiseal piping penetration seals are to maintain pressure differentials between rooms, and to prevent water and air leakage through wall, floor, and roof openings. They have been effectively used in nuclear and conventional power plants, refineries, and chemical plants.
Manufactured of durable, elastomer-coated fabrics, these seals allow lateral and axial movement of pipes up to several inches. Both bellows type and cone shaped seals have a zipper option that permits easy installation after piping has been installed. Zippered units have an air flap seal which overlaps the zipper and may be sealed with silicone for additional sealing. Non-zippered designs can be provided upon request.
Applications: nuclear and conventional power plants, refineries, chemical plants
Bellows and cone-type designs to allow lateral and axial movement

Any other application information, e.g. min/max/ambient temperature range, environmental exposure
(1) Select proper seal
(2) Unzip bellows or cone (suggest two man operation)
(3) Place around pipe or lagging & sleeve
(4) Rezip (suggest two man operation)
(5) Seal zipper opening with RTV silicone (suggest tube type applicator with nozzle). Allow 6 to 8 hours for silicone to cure. Do not disturb bellows until cure time has elapsed as it will loosen bond.
(6) position & tighten clamps on sleeve end. Extend bellows to dimension “C” “Live Length”. Position clamps on pipe end and tighten.
(7) Seal any cracks around bellows or collars with silicone to assure pressure tight seal.
