Double Rupture Disc Assembly prevents contamination.

Elfab Limited    Tyne & Wear, NE29 8SD
Feb 04, 2013 Available in materials ranging from stainless steel to Hastelloy and Duplex, Double-Disc Assembly comprises primary and secondary bursting discs that are both reverse-acting, both forward-acting, or combination, plus pressure gauge or switch to monitor space between discs. In event of chemical attack causing pinholing of primary disc, secondary disc prevents pollution of environment, while intermediate pressure sensor alerts process managers and maintenance teams of need to replace disc.

Pre-Torque Holders facilitate rupture disc installations.

Oct 11, 2012 Supplied in forward- or reverse-acting formats, Pre-Torque Holders are specifically designed to cope with installations where it is difficult to remove disc and holder separately from flange, and to minimize risk of disc slipping or of either component being damaged. Units are made of stainless steel for corrosion resistance, and comply with all internationally recognized flange standards. Holders are compatible with Elfab's Flo-Tel™+ magnetic burst detection system.

Portable Tool confirms correct rupture disc installation.

Mar 07, 2008 Designed to work with Flo-Tel(TM)+ burst detection system, Test-Tel eliminates risk of poorly fitted discs or incorrectly wired detection systems. For maintenance managers, unit ensures accurate rupture control and continuous function of devices by allowing non-invasive checking of alarms. Test-Tel performs range of rupture disc status tests, confirming operation of Flo-Tel+'s detection capabilities and Test-Tel's battery strength.

Wireless System monitors and relays rupture disc status.

Mar 06, 2008 Radio-Tel works with Elfab's non-invasive, magnetic rupture detection system, Flo-Tel(TM)+, for real-time process monitoring of disc status and temperature. When installed, Radio-Tel transmitters are situated close to rupture disc and plug into Flo-Tel+. Transmitters sends regular updates to receiver every minute, and immediate alerts are sent when rupture is detected. Radio-Tel failsafe receiver module can receive signals from 1,600+ ft away, and repeater aerials are available.

Burst Detection System includes onboard thermistor.

Nov 08, 2007 Installed on vent side of bursting disc, non-invasive, ATEX-approved Flo-Tel(TM)+ is fail-safe and only operates when disc has ruptured, eliminating false alarms. Unit includes built-in thermistor to monitor for temperature fluctuations. Available for use with all Elfab's core product lines, Flo-Tel(TM)+ is suitable for all levels of potentially explosive atmospheres in process temperatures ranging from -100 to 300°C.

Rupture Panel ensures bucket elevators operate safely.

May 07, 2007 Lift-Gard provides venting and rupture notification to guard against damage caused by explosions in bucket elevators transporting powder and bulk solids. Made of stainless steel, flat venting system combines integral frame and Flo-Tel(TM) detection device in one unit. If Flo-Tel(TM) detects initial explosion inside elevator shaft, it automatically switches off elevator motors to reduce risk of further explosion and stop elevator operation with open explosion vents.

Bursting Disk is designed for low-pressure applications.

Elfab Limited    Tyne & Wear, NE29 8SD
Jan 04, 2007 Intended for liquid, gas, or vapor applications from 2 psig, Opti-Gard(TM) SoLo reverse-acting bursting disk features 95% operating-to-burst pressure ratio and 3% performance tolerance. Unit comes pre-fitted with integral Flo-Tel(TM) non-invasive, magnetic burst-detection system, which is fail-safe and operates only when disk has ruptured. Standard construction is of corrosion-resistant Hastelloy®, but other materials are available upon request.

Rupture Disk Holders suit forward- and reverse-acting discs.

Elfab Limited    Tyne & Wear, NE29 8SD
May 04, 2006 Universal slimline rupture disk holders for Opti-Gard(TM) and Safe-Gard rupture disks feature standard face-to-face dimensions to facilitate replacement of existing holders. Holders incorporate multi-flanged design that interfaces with both Flo-Tel(TM) magnetic burst-sensing system and excess flow valves.

Pressure Relief Assembly prevents leakage problems.

Elfab Limited    Tyne & Wear, NE29 8SD
Sep 01, 2005 Designed to prevent environmental contamination in severe process conditions, Double-Disc Opti-Gard comprises primary and secondary rupture discs, as well as pressure gauge or switch to monitor space between discs. In event of chemical attack causing pinholing of primary disc, back-up prevents pollution of environment, while intermediate pressure sensor warns maintenance teams. Disc is corrosion-resistant Hastelloy C267 and features ±5% tolerance.

Explosion Vents feature ATEX-approved detection.

Elfab Limited    Tyne & Wear, NE29 8SD
Jan 21, 2005 Explosion vents are supplied with Panel Flo-Tel burst-detection device based on magnetically-actuated detection system that provides open signal once panel has operated. Panels are made from corrosion-resistant 316 stainless steel in sizes from 0.9–25.8 ft². Offered in various shapes, products operate over pressure range of 0.7–7 psig and in temperatures from -40 to +400ºF. Non-fragmenting design is suited for use in backpressure and vacuum conditions.
