Non-reclosing pressure relief device actuated by differential pressure and designed to function by the bursting of the bursting disc(s), and which is the complete assembly of installed componentsincluding, where appropriate, the bursting disc holder.
Conventional domed bursting discs shall be designed so that they burst due to tensile stresses when the bursting pressure is applied to the concave side of the bursting disc.
This type discs shall be domed by a means sufficient to cause a permanent set such that no further plastic flow occurs initially when the bursting disc is subjected to its intended operating condition.
Forward-acting, tension-loaded rupture disk design without score lines. Mounts into a 7A – Angle Seat Holder.
Features a state-of-the-art laser slotted metal top section. Mounts into a 7A – Angle Seat Holder.
The SFAZ forward acting rupture disks (bursting discs) are solid metal scored disk design. Designed to be used in the UHZ Holder.
Reverse domed bursting discs shall be designed to function due to buckling, bending or shearingstresses when the bursting pressure is applied to the convex side of the bursting disc
Covers the majority of medium pressure range rupture disk applications. Designed to be used in the RAH Holder.
Scored design covers the majority of high pressure range rupture disk applications. Designed to be used in the RAH Holder.
Covers the majority of high pressure range rupture disk applications. Designed to be used in the RAH Holder Designed to be used in the RAH Holder.
ARD Disks provide simple, inexpensive protection against any condition. No holder required.
Best Graphite Choice for Applications Involving Highly Oxidizing Agents and Halogens.
Dual Rated to Protect Against Two Different Pressures in Opposite Directions.
Designed for use with Inverted Type rupture disks.
Best Graphite Choice for elevated temperatures. Required for temperatures exceeding 430°F (221°C) to 700°F (371°C).
In addition to the standard type rupture discs, there are also special type discs which can be produced in variable types according to engineering requirements.
Many customer applications cannot be met using standard type rupture discs. In such cases special solutions are needed. A wide range of explosion discs are available with special fittings for demanding applications such as ultra high vacuum, OEM markets, military, aerospace and many other applications.

Extrusion Burst Plugs are pressure relief devices designed for over-pressure protection of plastic extrusion processes.
Designed for overpressure protection for Railroad Tank Cars and Tanker Trailers.
Disc holders are not required by all standards, but most applications. The biggest advantages of using a disk holder can be listed as follows;
It is a two-piece unit consisting of a base flange (inlet) and a fixing flange (outlet). The flat or 30 ° angled housing surfaces of these flanges are machined to grasp the bursting discs. When mounted, the top of the disc (domed portion) protrudes from the fixing flange and is metal-to-metal sealed.
The PTFE Sleeved holder utilizes a Teflon Encapsulated Viton O-Ring as standard. Ideal for corrosive applications and relieving the effect of product build-up.
Pre-Torque holder design allows removal of the assembly from the piping system for inspection without disturbing the seal intensity of the rupture disk.
The UHZ Type Rupture Disk (bursting disc) Holder is an insert type holder for flat seat style rupture disks (bursting discs).
Such holders have inlet and outlet elements which are screwed together with the bursting discs. The output element is also available in closed outlet design.
Designed for use with Inverted Type rupture disks. Ideal for pressure ratings from 20 psig (1.38 barg) to 1000 psig (68.97 barg).
Screw-Type are reusable type holders available in standard 30º angel or flat seat designs.
One-Time Use Rupture Disk Assemblies. Brass unit that comes pre-assembled with Rupture Disk and tested to meet your relieving pressure requirements.
Rupture indicators are used to provide immediate notification of rupture disc activation or disc leakage. Depending on the selected device, rupture indicators can be used to activate alarms, horns, remote warning devices, or interfere with existing control systems to ensure appropriate safety measures are taken.
Re-usable Rupture Disk Burst Sensor. Over-pressure indication for rupture disk or relief valve applications
Integral Rupture Disk Burst Indication. Over-pressure indication for rupture disk or explosion vent applications.
The Rupture Disk (bursting disc) Indicator or RDI Series is a simple and effective means of indicating when the process media ruptures a disk or opens a safety relief valve.
Used to monitor the space between a rupture disk (bursting disc) and safety relief valve or the presence of backpressure in a header system.
Gaskets are used to provide sealing and insulation. Sealing elements are used in leather, cork felt, lead, plastic, asbestos, paper, construction insulation and pipelines and chemical materials.
The PG Series Pipe End Covers install without tools and are meant to withstand severe weather conditions like rain, ice and snow and seals out insects, birds, nests, sand, dust and salt spray.
