36 Rupture Disc System Protection Devices Rupture Disc assemblies are designed to burst open and relieve an over pressure or vacuum condition at a predetermined differential pressure, and specific temperature. Applied between Mueller's RELIEFMASTER Change-Over Manifold and SAFETYMASTER Pressure Relief Valves, a rupture disc indicates which pressure relief valve has discharged. A rupture disc remains open after bursting, but when combined with a pressure gauge or high pressure switch, a visual or electronic indication of the burst is revealed. ASME Code Guidelines for the application of Rupture Disc Devices in combination with pressure relief valves is provided by ASME Code. The following is an excerpt from the ASME Code, Section VIII, Division I, UG-2. A rupture disc device may be installed between a pressure relief valve and the vessel provided: The marked capacity of a pressure relief valve, when installed with a rupture disc device between the inlet of the valve and the vessel, shall be multiplied by a factor of 0.90 of the rated relieving capacity of the valve alone. The space between a rupture disc device and a pressure relief valve shall be provided with a pressure gage, or suitable telltale indicator. This arrangement permits detection of disc rupture or leakage. Users are warned that a rupture disc will not burst at its design pressure if back pressure build up in the space between the disc and the pressure relief valve which will occur should leakage develop in the rupture disc due to corrosion or other cause. Compliance to ASME Code is the responsibility of the User. Look for these Mueller advantages: One piece brass construction. Non-fragmenting Rupture Disc. Dual Access Ports.

51 Technical Data Fitting Designations 4 o Flare Fittings TEES are described by first sizing the run ( to 2) and then the branch (). CROSSES are described by sizing the runs ( to 2 and to 4).. The first letter in the catalog number is derived form the name of the fitting, thus U for union, E for elbow, N for nut, etc. 2. The numeral following the letter symbol designates the combination of threads on the fitting: denotes external pipe to flare fitting U, E, T; 2 denotes a flare to flare fitting U2, E2, T2 and the letter R preceding the figure denotes internal pipe to flare fitting except in the Tee where denotes pipe thread to flare on the run.. The last two characters in the catalog number designate the size. Flare sizes are designated by numerals and pipe size by letters. 4. Flare nuts are NS4 for short forged nut, and N4 for long forged flare nut. R following the N denotes a reducing flare nut.. Pipe threads for refrigeration flare type fittings are in conformance with SAE J. Flared Tube Fittings Refrigeration Ful-Flo 4 Flared Tube Fittings are fabricated from brass forgings or drawn brass rod, eliminating the possibility of seepage by porosity.
