HPX-Ta™ Rupture Disc

HPX-Ta™ Rupture Disc

The HPX-Ta™ Rupture Disc 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 sulfuric acid. In certain concentrations, temperatures and moisture conditions, Tantalum is frequently the only suitable rupture disc material for the application.
 
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

Features


• 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)
• 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)
• Non-fragmenting design
• Fluoropolymer liner is available for corrosion protection on the process side of the rupture disc* (see note)
• 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

* Fluoropolymer liners are available on the process side of the rupture disc for:   
    1”, 1 ½” discs rated > 30 psig @ 72°F
    2” - 12” discs rated > 25 psig @ 72°F

**RATINGS, RANGES, TOLERANCES & MAXIMUM RECOMMENDED OPERATING RATIOS The HPX®-Ta Rupture Disc is available with the same ratings, ranges, tolerances and maximum recommended operating ratios as the (-90) version of the HPX® Rupture Disc. For details, please see the HPX® Product Family Standard Burst Pressure Ratings section of the HPX® Product Family literature.

***To optimize service life and rupture disc performance, Continental Disc Corporation manufactures and tests each HPX®-Ta Rupture Disc order for compressible or incompressible relief conditions as required by your application. HPX®-Ta Rupture Discs manufactured and tested only for compressible (gas/vapor) relief conditions may not function properly in an incompressible (liquid) application. Please state in your specifications and orders if a scenario exists for relief of incompressible media or if relief conditions exist only for compressible media.
