Flexicarb is an exfoliated graphite material with standard grades at 95% to 98% and a nuclear grade available at 99.5%. It can be supplied with an inorganic passivating inhibitor to increase its oxidation and corrosion resistance. Recent experiences and tests have shown that Flexicarb will oxidize over time. Care should be taken when considering the use of Flexicarb foil for applications above 330°C (650°F).
(Note: Flexicarb ST, SR and NR are the equivalents for Flexicarb RGS1, RGS3 and RGS4 which are the brand names used in the UK.)
> Flexibility of a proven spiral wound, low seating stress of a kammpro
> Graphite filled like a spiral wound, graphite faced like a kammpro
> Sigma PTFE inner ring barrier protects the flange from acid corrosion and also fills any existing corrosion damage
> Unique wire profile stores more elastic energy to create better dynamic performance and superior load retention in cyclic applications
> Excellent recovery (tested with 34% recovery @ 18K PSI [124 MPa], 30% compression)
> No spring washers needed, no re-torque required*
> Cycle over & over, and maintain sealability
Incredibly robust and resilient, metal-wound Change heat exchanger gasket is designed to deliver the most dynamic seal ever. Manufactured with proprietary equipment, using a 5-times thicker metal spiral and a unique laser welding process that penetrates completely through. So it requires no inner or outer ring, and is as easy to handle and install as a double-jacketed gasket. Best of all, it’s proven to perform without fail at least 60% longer than any other heat exchanger gasket, spiral wound, double jacketed, CMG, or Kammprofile, and that is a game changer.
