Forward Acting Rupture Disc STAR

STAR is a triple-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.

Applications

  • Separators, autoclaves, chemical reactors, desalination plants, flare stacks, FPSOs, gas-tight pressure vessels, gas compressor modules, gas turbines for power generation
  • Hazardous goods containers, geothermal energy, high pressure applications, intermodal containers for corrosive/ aggressive media, isolation of safety valves, condensers, power plants, cryogenic applications, cryostats + transport containers, LDPE (thermoplastic)
  • Food production, mixers, oil and gas separation and treatment, petrochemical plants, process vessels, refineries, reactors, spray dryers, reverse osmosis systems, heat exchangers, water injection pumps, silos

Description

Industries

  • Breweries
  • Chemical – petrochemical
  • Food
  • Oil and gas industry
  • LNG

Advantages

  • Minimal space required due to star-shaped opening pattern.
  • Cost-effective as different materials can be used for the individual elements of the rupture disc.
  • Minimum risk of fragmentation even at high pressures.
  • Also suitable for isolating safety valves.
  • Durable, low-profile solution – ensures superior performance and long life-cycle even where pressure cycling or vacuum conditions are present.
  • Corrosion resistant and cost-effective.
  • Unique star-shaped construction – low profile enables simpler installation and reduced holder costs.
