Carbone Lorraine Chemical Equipement Division - Graphilor® Graphite Rupture Discs

WHY BURST DISCS :

Burst discs are an accepted pressure relief device utilized to protect equipment, vessels, piping, and personnel wherever pressurized equipment is used. They are a cost effective method of providing safe and immediate venting of liquids and vapors. They may also be used in series with relief valves in which case they provide a corrosion resistant barrier protecting the relief valve.

WHY GRAPHITE BURST DISCS :

Unlike other materials such as metals, graphite is a unique material because it is not affected by thermal shock, is inert to corrosive atmospheres, is unaffected by material fatigue due to pressure cycling, and is accurate to pressures as low as 0.5 psig.

WHY GRAPHILOR® GRAPHITE BURST DISCS :

GRAPHILOR® is a resin-impregnated graphite which is virtually impervious to most corrosive liquids and vapors within its temperature/pressure rating. They are tested in accordance with the ASME code, Section VIII, Division 1, as such, they are destructively tested to confirm the burst pressure at requested temperature and records are maintained for traceability of each lot.

GRAPHILOR® GRAPHITE BURST DISCS HAVE THE FOLLOWING FEATURES :

Inert to most acids and corrosive compouds.
Burst pressure independent of temperature.
No fatigue failure - Pressure cycles to 75% of rated burst pressure without premature burst.
Accuracy to within +/- 5% of rated burst pressure at 15 psig and above.
Disc size, burst rating, venting capacity, bolt torque, temperature, and lot number clearly marked on each disc.
Full size range 1" - 24" nominal pipe size.
Standard burst ratings 5 psig through 150 psig - higher burst ratings upon request.
Standard dimensions for 150 psig ANSI flanges.
Computerized inventory for immediate shipment.
