Article: Creating reliable, durable seals in glass-lined steel equipment

United States

Equipment made of glass-lined steel is used when manufacturing or processing aggressive chemicals such as aniline derivatives and strong acids such as sulfuric, nitric or hydrochloric acid. The Achilles heel of such glass-lined systems is the gaskets needed to seal the joints between components. Exposure to aggressive media causes the seals to degrade over time, resulting in damage to equipment and posing a health risk to operators. Replacing the seals costs a great deal of time and effort, with a corresponding drop in production output. A newly developed gasket tape made of ePTFE (expanded polytetrafluoroethylene) is specifically designed to address the challenges of creating reliable seals in large glass-lined steel equipment.
