Case Histories
1
- Ethylene cracker units
- 1300ºF service
- Flexible graphite gaskets lasted
only 3 to 6 months
- Hydrocarbon leaks resulted in flash
fires and unplanned shutdowns
- Style CGI spirals, heat treated
Inconel X750 with Thermiculite 835 filler extended service beyond 1-1/2 years until scheduled shutdown
- Net result was increased production and elimination of safety related issues, resulting in savings “in the $millions”
