Elastagraph™ gaskets are produced by infusing seamless layers of flexible graphite at varying densities and thicknessess over a corrugated metallic core. Elastagraph™ utilizes a unique corrugated pattern which increases the depth of the groove and the pitch at the peak of the corrugation. This greatly improves the gaskets sealability over traditional corrugated designs.
Elastagraph SG is designed specifically to solve fugitive emission and compliance problems. It also has excellent performance in bolted joints that experience thermal cycling or limited initial bolt load. Elastagraph™ is the most economical way of meeting low emission requirements.
Excellent sealing against vaporous and media like gases and thermal (hot) oil.
Elastagraph SG flange gaskets can be used in a wide variety of media, i.e. a pH range varying from 0-14. Application / compatibility guide is available on request. Pressure from vacuum to ASME class 600lbs and DIN/EN class PN40. Temperature from -400 ºF to 850 ºF (steam 1200 ºF).
All non-standard pipe flange configurations with and without bolt holes according customer specifications or Edrawing.
