SAF-T-GRAF? Replaceable Element Graphite Disks - 2

I IEATURES & IIOTES SAF·T·GRAF®FEATURES OPERATING RATIO • Fail-safe -the same burst pressure in either direction (Model RE). Up to 80% operating pressure to burst pressure ratio. • Offers superior sealing characteristics to process gases and fluids. • Burst pressures of armored disks are unaffected by excessive or uneven torquing of the flange studs. The disks are designed to be assembled into separate safety heads before insertion between standard pipe flanges. • Higher operating temperatures than other graphite disks (up to 205°C/400°F). FLANGE RATINGS • Operating temperatures to 427°C...

I•OIEL RE, REL DISKS & RE·7R, REL·7RSAFETYHEADSI MODEL RE The unique fail safe design of the RE type disk assures the disk cannot be installed incorrectly in the safety head as the disk will burst at its rated burst pressure in either direction. Additionally the disk and safety head assembly may be installed in either direction between pipe flanges. A disk with a burst pressure of 1.52 bar (22 psig) or above will withstand full vacuum. RE·7R SAfETY HEAD The RE type disk is installed in a precision machined RE-7R safety head for direct installation between standard international pipe...

[MODEL REV DISKS & REV·7R SAFETY HEADS MODEL REV The REV type disk is suitable for applications where vacuum conditions exist and when the burst pressure is less than 1.52 bar (22 psig). Type REV graphite disk in REV-7R graphite safety head. A REV disk inserted in a REV-7R safety head is used in applications where vacuum conditions exist and when the rated bursting disk pressure is less than 1.52 bar (22 psig). A locating pin on the disk mates with a location hole in the safety head thus eliminating incorrect installation. The REV-7R safety head is provided with an integral non-opening...

ltiRDERIIIG INFORMATION DISK STYLES CORROSION RESISTANCE Impregnated graphite is resistant to most corrosive media. A bursting disk can be supplied with a TFE liner attached to the process side of the disk for extra protection against corrosion and prevention of product build-up. Specify Model REL. FLANGE RATING The safety head can be supplied to fit flange ratings ANSI, DIN, AFNOR, BS, and JIS. Please advise flange specification when ordering. Order replacement disks by lot number (or part number) indicated on disk tag. SAFETY HEAD STYLES OPERATING RATIO SIZES 25mm (1 ")to 600mm (24"),...

ORDERING INfORMATION TEMPERA TURf BURST TOLERANCE SAF-T-GRAF graphite bursting disks are suitable for use at temperatures from -73°C (100°F) to 205°C (400°F). Higher temperatures up to 427°C (800°F) are accommodated using a high temperature assembly. The burst tolerance is the maximum variation from the rated burst pressure. RATED BURST PRESSURE less than 0.07 bar ( 1 psi g) If a disk is ordered with a burst temperature within 4.5°C (40°F) to 38°C (1 00°F) it will be burst tested and rated at 22°C (72°F). If the requested temperature is outside this range (4.5°C (40°) to 38°C (l00°F)) the...
