Because rapid pressure relief is required for overpressure protection, rupture discs are a common solution; however, these challenging, high pressure/high temperature applications can cause traditional rupture discs to fatigue over time. The Rembe high pressure rupture disc (HPRD) has a much longer life than traditional discs because the pressure load applies only on the seat of the disc. By moving the weld seam out of the pressure loaded area of the disc, the burst pressure is defined only by well controlled parameters such as material thickness and it is not influenced by the strength of the weld seam. This precise control over the rupture disc response pressure also allows the tightest burst tolerances of +/- 3% and lower.
