Leader ElastaGraph®Emission Reduction Gaskets

Leader ElastaGraph SG Pipe Flange Gaskets

Description

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.

Product Data Sheet

Application

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.

Advtantages

Excellent sealing against vaporeus and media like gases and thermal (hot) oil

Chemical Compatiblity

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).

Delivery Options

All non standard pipe flange configurations with and without bolt holes according customer specifications or E drawing
