Poly-SD Series Rupture Disc
Brand: Fike CorporationThe Fike Poly-SD rupture disc is a versatile disc. The Poly-SD can be used in liquid, vapor and two phase flow and is available in a large variety of materials.
The patented, smooth design of this rupture disc (free from ledges or crevices preventing material buildup on the disc), also makes the Poly-SD ideal for polymerization processes.
In addition, the non-fragmenting Poly-SD rupture disc is well suited for pressure relief valve isolation from process contaminants and corrosion.
Features- Patented, smooth annular seating design helps prevent material build-up on disc
- Created with a fail safe design which provides pressure relief at or below its rated burst pressure even if damaged or installed upside down
- Scoring on the downstream side controls the burst pressure and opening characteristics.
- The Poly-SD series includes 3 different scoring configurations to optimize performance over a wide range of pressures
- Can be used in liquid, vapor or multi-phase media applications
- Can be operated as high as 90% of its rated burst pressure
- Withstands full vacuum without a vacuum support in a wide range of pressures
- Designed to be non-fragmenting
- Available with a zero manufacturing range
