is a Tantalum semicircular scored reverse acting rupture disc designed specifically for use in highly corrosive media, such as bromine, chlorine, HCL, nitric acid or sulphuric acid. In certain concentrations, temperatures and moisture conditions, Tantalum is frequently the only suitable rupture disc material for the application. APPLICATIONS The HPX-Ta Rupture Disc can be used in a wide range of applications in many different industries, some of which include: OFFERS RESISTANCE IN HIGHLY CORROSIVE APPLICATIONS EDITED PHOTO TO COME PETROCHEMICAL/AGRICULTURAL CHEMICAL // Reactors, Storage Vessels, Heat Exchangers, Discharge Heads, Safety Relief Valve Isolation OIL & GAS // Distillation Columns, Separators PHARMACEUTICAL // Production Vessels, Heat Exchangers INDUSTRIAL GAS // Process Columns and Vessels, Storage & Transportation Tanks SEMICONDUCTOR PRODUCTION // Specialty Gas Distribution & Storage Sizes available: 1"-12” Tantalum rupture disc material for corrosion protection 316 SS standard outlet ring material, HASTELLOY C®, Tantalum and other materials available upon request Cyclic durability designed for a minimum of 1,000 cycles from full vacuum to the maximum recommended operating pressure 90% maximum recommended operating ratio** (see note on next page) Safety ratio of 1 to 1 or less. If the rupture disc becomes damaged, it will relieve at or below the burst pressure Ideal for liquid or gas/vapor applications*** (see note on next page) Non-fragmenting design Fluoropolymer liner is available for corrosion protection on the process side of the rupture disc* (see note on next page) Fluoropolymer outlet protective cover available for corrosion protection on the vent side of the rupture disc and holder ASME Code Section VIII, Division 1 compliance available when requested. National Board Certified KR flow resistance values when installed in the HPX Insert and HPX-PT (Pre-Torqued) Holders: KRG (gas) = 0.29 and KRL (liquid) = 0.38 Available option: Cleaned for oxygen or chlorine service In compliance with the Dodd-Frank Act, our Tantalum is procurred from conflict-free smelters BENEFITS Provides lower maintenance cost, greater reliability as compared to alternate rupture disc types or materials Compatible with the HPX® Insert, HPX-PT® (pre-torqued) or HPX® Double Disc holders Holder corrosion resistance can be enhanced by Tantalum lining or coating of the holder inlet and/or Tantalum coating of the outlet holder Tantalum lined HPX-PT® (pre-torqued) holders are ideal for use on vessels or pipe spools having protective lined flanges Increased productivity of your system PERFO RMANC E
