James Walker has launched two multi-purpose gaskets certified as fire safe to ANSI/API Standard 607 and ISO 10497-5:2004 for critical CPI/HPI applications.

Metaflex SG/IR Fire-Safe is a spiral-wound gasket constructed from a 316L stainless-steel inner support ring, winding strip with PTFE inner seal, graphite outer seal material and carbon-steel outer ring material on standard design.

The second product is a corrugated gasket variant, the Corrusafe FS, which comprises a 316L stainless-steel corrugated ring with PTFE inner envelope and graphite outer seal material.

Both products are available in sizes from 1/2in to 48in in accordance with all relevant gasket standards and flange designations.

Both gaskets are capable of tolerating continuous operating temperatures of up to 260C.

The Metaflex SG/IR Fire-Safe has a maximum pressure of 350 bar, while Corrusafe FS has a maximum pressure of 50 bar.

The Metaflex SG/IR Fire-Safe and Corrusafe FS products completed the independent fire type-test recording zero leakage under all conditions against a permissible figure of 17ml during the fire and 500ml post-burn.

Metallic and semi-metallic gaskets are said to be a key strength within the James Walker sealing product range, which also includes graphite, PTFE and non-metallic gaskets for all sealing applications and industry sectors, particularly those with extreme mechanical and thermal performance demands.

The company also provides a 24-hour emergency breakdown service specifically to cater for the operational environments and needs of worldwide oil, gas, petroleum and chemical processing industries.
