Description

Reverse buckling bursting discs are scored, full metal components of nickel, nickel-based materials (Inconel, Hastelloy)* or stainless steel. They are mainly used in processes with medium and high pressures, high operating temperatures and considerable pressure fluctuations. The principle of the Euler buckling pin is used: reverse buckling bursting discs are domed opposite to the pressure direction. Upon reaching the burst pressure the dome reverses and ruptures along the scoring. Their special design makes reverse-buckling bursting discs very resistant against high operating pressures and alternating-pressure loads as well as high operating temperatures. The longer service life of the bursting discs and the associated, lower expenses for downtimes, maintenance and replacement bursting discs are advantages our customers appreciate. We produce reverse-buckling bursting discs in two versions: cross-scored (Type UX) or round-scored (Type U) discs in standard sizes from DN 15 to DN 300. They can withstand pressures between 1 and 400 bar and temperatures between minus 50 and plus 450 degrees centigrade. Customised versions with varying materials, pressures and dimensions are also on offer.
