CRANE-FOIL™ - 1

CRANE-FOIL™ FLEXIBLE GRAPHITE GASKET Product Description John Crane’s Crane-foil™ is a premium grade flexible graphite gasket material used in a wide range of services, where conventional gaskets will not withstand extreme temperature and/or pressures. Crane-foil gaskets feature the benefits of graphite including resistance to most fluids, high temperatures, and pressure changes. They provide excellent sealing, preventing product leakage, and minimizing change outs. Resistance to cold flow, weathering and aging make Crane-foil ideal where increased reliability is necessary. Crane-foil has excellent compressibility characteristics under moderate loads, further reducing costs associated with installation and bolt retorquing. Technical Specification Performance Capabilities • Temperature: Oxidizing: -240˚C to 455˚C/ -400˚F to 850˚F Non-Oxidizing: -240˚C to 3000˚C/-400˚F to 5432˚F Steam: up to 650˚C/1200˚F Stainless Inserted: -240˚C to 1000˚C/-400˚F to 1800˚F • Pressure: up to 136 bar/2000 psi • Stainless Inserted: Up to 680 bar/10,000 psi • P x T Maximum: 1,600,000 (˚F x psi) / 58,000 (˚C x bar) • pH Range: 0-14 (Except strong oxidizers) Stainless steel inserted gaskets provide additional strength for higher pressure applications and additional resistance to damage from handling and installation. They are highly recommended for narrow cross section gaskets. Construction/Features Crane-foil sheet and gaskets are manufactured from high purity exfoliated graphite, precisely calendered into a foil. It contains no fillers or binders that can lead to fluid contamination.
