Change™ and Flexpro® Corriculite® Faced Gaskets for Heat Exchangers
Corriculite®-The Anti-Corrosion Heat Exchanger Gasket - Kammprofile and Spiral Change®Styles
Corriculite™ tackles the problem of flange face corrosion on bolted joints in seawater and hydrocarbon applications.
Responding to customer demands for an improved material with strong anti-corrosion characteristics Flexitallic has created Corriculite® – a filler material for spiral wound gaskets specifically designed for use in corrosion-sensitive environments, such as seawater and hydrocarbon services, across a number of industries, including oil and gas, power and marine.
This revolutionary, non-conductive filler material provides sealing performance and corrosion resistance unlike any other gasket material on the market. Comparative tests show Corriculite® delivers corrosion protection and sealing properties that far exceed other materials currently available.
Conventional graphite gaskets for instance, promote the initiation and propagation of corrosion of flanges due to graphite’s electrical conductivity and position in the galvanic series, leading to premature failure and leakage.
Due to recent successes in the oil and gas industry and increased customer demand, we are pleased to announce we have added API 6FB Fire-Safe approval to our Corriculite™ product portfolio as follows:
Flexpro® Kammprofile
Change™ Gasket
Metal-wound gasket designed to deliver a seal with the most dynamic recovery, in corrosion sensitive applications.
The Change™ Gasket is available is a wide range of filler and facing materials, including Flexicarb SEL Graphite, PTFE, Thermiculite and Corriculite.
The high level of stored energy gives the Change gasket extremely high recovery. In a compression test against other gaskets, the Change Gasket recovered almost five-times better than a Kammprofile or DJ gasket.
Available in Styles CG (winding with outer ring), CGI (Winding with inner and outer rings), RIR (winding with inner ring), R (winding only). Also available with pass bar configurations for heat exchanger applications. (Note, DJ (Double Jacketed) pass bar configuration is used).
Standard winding heights are .125″ and .177″. See Flexitallic Engineering for appropriate winding wire height.
