High-pressure rupture discs now have extended service life

| By Chemical Engineering



Since this company’s engineers have modified the standard rupture-disc design, its high-pressure rupture discs (photo) have become significantly more durable. The welding seam of the rupture disc is not stressed as usual, in terms of shearing and bending, but only in terms of pressure. Through the geometric separation of the stress spike and the welding seam, the rupture disc is longer-lasting and allows the lowest rupture tolerances of up to±3% at pressures of up to 5,000 bars and temperatures up to 400°C. — Rembe GmbH Safety + Control, Brilon, Germany
