Fike Poly-SD Rupture Disc

Scored, Forward-acting

The versatile Poly-SD rupture disc can be used in liquid, vapor and two phase flow and is available in a large variety of materials.

Poly-SD

Specifically designed to help prevent material buildup on the rupture disc, the Poly SD is ideal for polymerization processes.

  • Provides pressure relief at or below its rated burst pressure, even if damaged or installed upside down
  • Different scoring configurations offer optimized performance over a wide range of pressures.
  • Operates in liquid, vapor and multi-phase media applications
  • Can be operated as high as 90% of rated burst pressure
  • Can withstand full vacuum without vacuum support, in a wide range of pressures
  • Non-fragmenting
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves


How Rupture Discs Work

A rupture disc is a non-closing pressure relief device used to protect industrial applications from overpressure- or vacuum-related events. Learn about how rupture discs work and what sets Fike apart in its rupture disc manufacturing process.
