Weather Shield Secondary Seal

Name: Weather Shield Secondary Seal Manufacturer
Brand: Vyapar Infotech
Rating: 5.0 (4992 reviews)

A Weather Shield Secondary Seal is a protective secondary rim sealing system installed around the perimeter of External Floating Roof Tanks (EFRTs), between the floating roof and the tank shell. It is designed to provide an additional protective barrier over the primary rim seal, protecting it from external environmental conditions such as rain, ultraviolet (UV) radiation, dust and wind.

The Weather Shield Secondary Seal consists of metallic weather shield plates fitted with a resilient sealing element underneath. The metallic shield provides mechanical and environmental protection, while the resilient sealing element maintains effective contact with the tank shell to minimize the entry of rainwater, dust and other external contaminants into the annular rim space.
