In response to growing industry demand and increasingly strict safety legislation, James Walker has launched two new multi-purpose gaskets certified as Fire Safe to ANSI/API Standard 607 and ISO 10497-5:2004, for critical CPI / HPI applications.

Both products are available in sizes from ½" to 48" in accordance with all relevant gasket standards and flange designations. They are capable of tolerating continuous operating temperatures of up to 260°C.

Metaflex^® SG/IR Fire Safe is a spiral-wound gasket constructed from a stainless steel inner support ring, winding strip with PTFE inner seal, graphite outer seal material and carbon steel outer ring material, on standard design. Metaflex SG/IR Fire Safe has a maximum operating pressure of 35MPa.

The second product is a corrugated gasket variant, the CorruSafe FS, composed of a stainless steel corrugated ring with PTFE inner envelope and graphite outer seal material. This product has a maximum operating pressure of 5MPa.

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