Wearflex® Expansion Joints and Bellows

Specially designed for applications against wet flue gasses and high acid content

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)

ATEX environment

We specially designed electrically conductive fabrics, that can be applied in our Wearflex® ATEX expansion joints. These fabrics are tested and certified by an independent organization to be electrical conductive to avoid static electricity during operation. The temperature range of our Wearflex® ATEX expansion joints is 0 - 400°C, with a pressure range of -50m Bar to +150m Bar. We also deliver Wearflex® ATEX rubber expansion joints, which are mainly used in transport pipelines to transport gases, oils, food, cooling and waste water.

Special Fabric Expansion Bellow certification

Insulcon has achieved the certification of the "Gütezeichen RAL-GZ 719". This certificate is a highly recommended quality mark of manufacturers of fabric expansion joints (bellows). Please read this news item for more information.
