STENFLEX® fabric expansion joints are chemically resistant to acid and alkaline gases and remain stable at overpressure or underpressure. They are extensively used for pipeline systems working with gaseous media at high temperatures up to +700°C. Plant and equipment engineering for conveying hot air or flue gas is a typical application.
