  • Wearflex® Q-Chem Expansion joint

    Wearflex® Q-Chem expansion joints are specially designed for applications in which resistance against wet flue gasses and a high acid content is critical.

    Q-Chem expansion joints are produced through the process of heat-sealing.The special shape of Q-Chem expansion joints is obtained by sealing special shaped reinforcements into the base material. In this way a 100% gas tight expansion joint is achieved. By using a combination of different materials, special designs are being made for flue gas systems with chemical or abrasive components and for systems operating under extreme conditions.

    Our Wearflex® Q-Chem expansion joints are available in four standard classifications:

    * Q-Chem LT up to 250°C

    * Q-Chem MT up to 540°C

    * Q-Chem HT up to 1370°C

    * Q-Chem GTX up to 650°C (specially developed for gas turbine outlets)
