Under Pressure - how to safeguard high pressure processes Usual high pressure rupture discs: Pressure loaded weld seam (red), affected by tension forces due to their position. New REMBE HPRD high pressure rupture disc: The weld seam (green) is not affected by tension forces thanks to the innovative rupture disc design. EMBE HPRD rupture discs protect various high pressure processes around the world. They were recently approached by one of the leading multinational companies to protect their polymer plant in Belgium and help to bring them in line with European regulations on pressure equipment. R “The challenge of high pressure applications is one which our engineers relish and we are proud to be able to protect such processes” said Claire Lloyd, Business Development Europe at REMBE. 96 PECM Issue 32 High Pressure applications require special overpressure protection due to the demanding process conditions including pressures up to several thousand bar and temperatures over 300˚ C which mainly occur in autoclaves. Related compressors face similar pressures. Therefore, the burst pressure is defined only by well known factors such as material thickness. By moving the weld seam out of the pressure loaded area of the disc, REMBE HPRD rupture discs have a much longer life time than comparable discs as the pressure load applies only on the seat of the disc which also allows tightest burst tolerances up to +/- 3% and lower.
