High Pressure Rupture Disc HPRD

The geometry of our rupture discs offers you a valuable innovation: more stable and more durable rupture discs.

By modifying the design of our existing rupture discs, we have made a crucial improvement: Unlike other high pressure rupture discs, the weld seam is not subjected to shear and bending forces – only to pressure. Anyone with a technical knowledge of this area understands that this makes a major difference. Geometrically separating the area under peak stress and the weld seam makes the rupture disc more durable and able to comply with the tightest burst tolerances – tolerances of +/- 3 % and better, depending on the specified burst pressure.

The new HPRD rupture discs provide long-term protection for processes with temperatures up to 400 °C and pressures up to 5000 barg and beyond. They have already proved themselves under real process conditions and in a wide range of customer applications. These include reactors, autoclaves and compressors in a variety of high pressure processes, such as LDPE production.



  • Autoclaves
  • Chemical reactors
  • Gas-tight pressure vessels
  • High pressure applications
  • LDPE (thermoplastic)
  • Petrochemical plants
  • Reactors
  • Water injection pumps


  • Chemical – petrochemical
  • Oil and gas industry


  • Extra-long service life even at the highest temperatures and pressures
  • Burst tolerance of +/- 3 % prevents premature rupture disc response and thus production standstills.
  • Design can be adapted in any way.
