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™ 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™ 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.

Delivery Options

Standard gaskets are available in accordance with ASME B16.21 (1/2” – 24”) , EN12560-1 as well as EN1514-1 (DN10- DN600). Standard thickness is 1,6 mm (1/16”) and 3,2 mm(1/8”).Non-standard, or special gaskets, can be manufactured according to patricular customer drawings, or by given sizes. Please note that tooling may be required.diameter of 4000 mm. We have a large stock in SS316L. Other materials are also available.
