1-800-328-2720 A Game Changer Flexitallic invented the spiral wound gasket in 1912, there was nothing like it. 100 years later, They introduced the Change gasket-an incredibly resilient metal-wound gasket that’s designed to deliver the most dynamic seal ever. Today there are thousands of Change gaskets in service. Change is manufactured with proprietary equipment, using a 5 X thicker metal spiral and a unique laser welding process that penetrates completely through the winding so it requires no inner or outer ring. Best of all, it’s proven to perform without fail at least 60% longer than any other gaskets, CGI Spiral Wound, Double Jacketed, CMG, or Kammprofile. Thermal cycle test Across a 24-day, 24-cycle pressure vs thermal cycle test at 608°F (302º C ) replicating industry application conditions, the Change gasket lost just 1.5 PSI. total, never coming close to the failure point. 4” Class 300, RF, B16 studs • Thermal Cycle Phase – Purge and Heat up to 608°F (302°C) at 3.5°F/min Pressurize to 480 psi Hold 1 hr Unassisted Cooling to Ambient Repeat 24 times unless gross failure occurs – Approximately 24 hours per cycle • Record pressure drop every cycle • Max allowable P drop: 14.5 psi Change Gasket Summary Construction is more robust than a Spiral and Kammprofile Compression is more consistent than a Spiral and Kammprofile Creep is VERY low Recovery is VERY high Seals with exceptional tightness, especially thermal cycles Crush resistant; no inner ring/compression stop required Fits most – if not all – flange arrangements • Available in all industrial metals April 8, 2016dooley Post navigation Previous Previous post: Thermiculite, a Breakthrough in Both Heat and Chemical Resistance Categories Uncategorized Archives April 2016 February 2016 January 2016 December 2015 November 2015 May 2013 Home About Products Services & Capabilities Resources Blog Contact Terms & Conditions Privacy Policy 838 Sussex Blvd. Broomall, PA 19008 Phone: 1-800-328-2720 Fax: 610-328-6599 Office Hours Monday to Friday 8:30 AM to 5:00 PM Copyright © 2021 dooleygasket.com Website Design by IQnection - A Digital Marketing Agency
