Extruder Rupture Disks/Blow Plugs

Extruder Rupture Disks Blow/Burst Plugs - Description:

NPH Extruder Rupture Disks (Burst Plugs) are primarily used on Plastics Extrusion Machinery to provide emergency pressure relief. Extruder Rupture Disks from NPH are designed to instantaneously rupture at a pre-determined pressure. Extruder Rupture Disks are leak tight and intrinsically safe devices that require no maintenance.

NPH Extruder Rupture Disk assemblies are manufactured from 304 SS and incorporate either an Inconel or Stainless Steel Disk which minimize the affects of varying processing temperatures. The RD Series of Extruder Rupture Disks from NPH are offered

in a wide variety of lengths and configurations. Standard stock assemblies are available in burst pressures ranging from 1,500 up to 15,000 psi, and lengths from 1.82" up to 12". Several different mounting threads are offered on the NPH RD Series Extruder Rupture Disks that are commonly found on plastics extrusion machinery.
