Flexitallic Change™

Originally designed to solve the issues associated with sealing thermally and pressure cycling shell and tube heat exchangers, Change gaskets are BAT sealing technologies for Pressure and Thermally cycling applications, providing at least eight times the reliability of other sealing technologies. Change is fire safe to API 6FB. The Change gaskets outstanding resilience and strength enable the necessary stress to be maintained in the bolted connection and therefore reliable sealing, even under the most arduous temperature & pressure cycling conditions. Change can be manufactured with both Corriculite® and Thermiculite® windings and facings, to meet application demands.
Change gasket technology is written into the piping specification of a major gas producer, for Hydrogen service.
Shell Thermal Cycle test – Change sealing performance was tested and compared with other gasket sealing performance - 24 thermal cycles, ambient to 320oC and back to ambient, ⁄2 day per cycle. 33Bar Nitrogen applied. Test fail at 1 bar pressure drop – 32Bar.
Flexitallic’s Change technology reliably outperforms other market alternatives in cycling applications.
