SELECTING A RUPTURE DISC In many cases, the type of rupture disc for a given application may be found using the following steps: 1. To select the proper rupture disc for any application, it is important to begin by writing down specific data about your system. a. Maximum allowable working pressure of the vessel (MAWP): psig, barg, kg/cm2, etc. b. Maximum operating conditions: Pressure: psig, barg, kg/cm2, etc. Temperature: degree of Fahrenheit, Centigrade, etc. c. Rupture disc burst conditions: Pressure: psig, barg, kg/cm2, etc. Temperature: degree of Fahrenheit, Centigrade, etc. d. Process media:...

TYPE OF DISC No single type of rupture disc will meet all the numerous applications of an industry. Each type of rupture disc, Tension or Reverse Acting, has its own characteristics and capabilities. Tension Type Rupture Discs Reverse Acting Rupture Discs Fig. A Fig. A Process Side Process Side Fig. B Reverse Acting rupture discs are oriented in a system with the process media pressure against the convex side of the disc (Figure C), placing the rupture disc in compression. As the burst pressure rating of the disc is reached, the compression loading on the rupture disc causes it to reverse, snapping...

REVERSE ACTING HPX™ Rupture Disc SANITRX HPX™ Rupture Disc FEATURES • The HPX™ & SANITRX HPX™ rupture discs are high precision scored reverse acting rupture discs that offer proven performance in excess of 250,000 cycles at a 95% operating ratio. • Choice of 90% or 95% maximum recommended operating ratio • Safety ratio of 1 to 1 or less. If the rupture discuss becomes damaged, it will relieve at or below the rated burst pressure. • Non-fragmenting design • All SANITRX HPX™ rupture discs include sanitary, environmentally friendly, non-toxic packaging SPECIFICATIONS: SPECIFICATIONS: Sizes: 1” -...

REVERSE ACTING ULTRX® and LOTRX® Rupture Discs These scored reverse acting rupture discs utilize our failure initiating indents, a highly accurate manufacturing method to achieve and control a burst pressure at close tolerances, plus a precision semicircular score to provide a clean, consistent opening pattern. ULTRX® Rupture Disc LOTRX® Rupture Disc Sizes: 1” - 12” (25mm - 300mm) diameter Burst pressure: 15 to 1000 psig @ 72°F (1,03 to 68,9 barg @ 22°C) Sizes: 1” - 8” (25mm - 200mm) diameter Burst pressure: 1.5 to 39.9 psig @ 72°F (0,103 to 2,75 barg @ 22°C) COMMON FEATURES INCLUDE: SPECIFICATIONS:...

REVERSE ACTING RCS Rupture Disc Assembly SANITRX® Rupture Disc The RCS Rupture Disc is a reverse acting, crossscored, solid metal rupture disc, providing reliable pressure relief protection, easy installation, and retrofit to your preexisting piping arrangement. The SANITRX® Rupture Disc is a reverse acting, solid metal rupture disc with Continental’s “failure initiating indents,” designed to provide overpressure protection in sanitary environments. Also available, the SANITRX LP® Rupture Disc, with lower pressures and a much lower KR factor, available in 1”- 3” (25-80mm) size. SPECIFICATIONS:...

TENSION TYPE MICRO X® Cross Scored Rupture Disc Composite Flat Seat Rupture Disc The MICRO X® Rupture Disc is a cross-scored flat seat tension type rupture disc. It is designed for nonfragmentation with a four-petal opening. The Composite Flat Seat Rupture Disc is designed for systems requiring a lower burst pressure than offered in a MICRO X® Rupture Disc.
