Rupture discs protect various high pressure processes

Louise Smyth

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.

Rembe HPRD rupture discs protect various high pressure processes around the world. The company was recently approached by one of the leading multinational companies to protect its polymer plant in Belgium and help to bring it in line with European regulations on pressure equipment.

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 the tightest burst tolerances up to +/- 3% and lower. Therefore, the burst pressure is defined only by well known factors such as material thickness.

“The challenge of high pressure applications such as LDPE production is one that our engineers relish and we are proud to be able to protect such processes,” says Claire Lloyd from Rembe.
