Poly-SD Rupture Disc
DESCRIPTION
The 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 AND BENEFITS
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
