STAR is a three-section solution primarily used in applications with low to high response pressures, especially in the oil and gas industry, petrochemicals and chemicals, applications with liquified gases and processes that involve pressure cycling. The standard operating ratio is up to 80 %* of the minimum response pressure. Extremely tight tolerances of +/- 5 % are possible. For applications with a burst pressure of less than 1 barg, STAR can be installed directly between flanges.
The advanced manufacturing process guarantees minimum fragmentation when opening even at the highest pressures. Its star-shaped opening pattern is flatter than that of other rupture discs so it requires less installation height. The integrated vacuum support guarantees high vacuum resistance.
STAR comprises three layers, a top section, a sealing membrane and an integrated vacuum support. As the critical burst element is not in contact with the process media, this can be sourced in less exotic materials enabling the STAR rupture disc to be a cost-effective solution even for the most corrosive operating conditions. The sealing membrane ensures high leak integrity of the disc, reducing the risk of loss of process media during normal operating conditions. Using a metallic seal ensures the long-term robustness and performance of the rupture disc even where harsh process media is present. The integrated vacuum support guarantees high vacuum resistance. The material selection of this rupture disc is fully customisable to best meet process onditions and budget requirements.
