An arrestor is a passive safety device designed to disperse a Flame front, release its energy, and cool it to below the ignition point of that vapour.

Comparing them to competitors models reveals defi nite advantages and value in the following features: Gasket integrity Flame propagation stoppage through the full fl ame front spectrum Longest continuous-burn time ratings Eliminating fl uid traps (offset models) Approved for branch line applications that use a larger header pipe versus a smaller branch line equipped with a Detonation fl ame arrestor Guaranteed cleanabilityPatented Flame Quenching ProcessTornado s patented fl ame quenching process incorporates a ceramic bead pack to segregate and cool an approaching fl ame front, which quenches or snuffs out the combustion.

4 The ceramic bead pack is corrosion resistant. The ceramic beads can be taken out, cleaned and reinstalled, saving the end user substantial costs and restoring original pressure drops. The ceramic bead pack also is not affected by continuous burn conditions as the maximum temperature rating of the alumina ceramic is well over the melting point of carbon or stainless steels. This feature ensures the fl ame barrier between safety and danger remains broad for personnel and equipment protection 25 years we have witnessed most every possible onsite condition. More often is the chance of a continuous burn occur-ring than that of having a severe fl ash back. The majority of continuous burns are severe, but only last about 1 hour. Generally they are detected and addressed, or the process condition changes. Inadequate Detonation Arrestors can pose a real danger as during a continuous burn, if the fl ow is shut off, the fl ame can jump through the element once the velocity drops and failure can occur.

5 If you are safety minded, invest in best Tornado Sure Stop Detonation Arrestors . The Highest Regulatory ApprovalsTornado has spent countless hours, effort and dollars in research, testing and redesigning our product to achieve the highest burn ratings on the market. Tornado test methods were supervised by the USCG and CSA, culminating in the industry s highest rated Detonation arrestor for performance. No other manufacturer can parallel our burn ratings. Tested & passed for entire fl ame spectrum with no propagation of fl ame to protected side US Coast Guard approved as Type 1 Detonation arresters Tornado DA s have been tested to both the USCG standards and CSA standards and passed the tests receiving Type 1 and Class 3 burn ratings respectively Tornado assisted in creating the CSA standard test method for Inline Flame Arresters and Firebox Flame Arresters CSA Z343-98 Low, medium & high-pressure defl agrations for Group C & D gases (NEC) Overdriven & stable detonations for Group C & D gases (NEC) Installation anywhere in piping confi gurations vertically, horizontally or at any angle desiredDetonation Arrestors - IntroductionTORNADO Technologies Inc.

This ensures superior resealing during cleaning and maintenance. This rugged inline design has been very popular for a wide range of uses. The inline design must be installed at a 45 angle, due to the fact that if installed in the horizontal position there is a low spot for fl uid ILSF-A incorporates a 1 thick continuous burn grid versus a 11/2 thick grid used in the OSDF and OSSF (offset designs provide more protection because they are thicker, translating into an extra cost). The ILSF-A has been tested and independently verifi ed to pass the 2-hour continuous burn requirements of the USCG. The ILSF-A units are adequate for general applications at an affordable price.

7 Compare continuous burn times to other units on the market and see the difference. The ILSF-A is the best all-around Detonation arrestor used in many (In line Single Flame -B)The ILSF-B Sure Stop Detonation arrestor incorporates all the working features of the ILSF-A with only one difference the fl ame quenching element does not have a machined gasket face on it. Spiral wound gaskets cannot be used. The ILSF-B uses sheet gaskets compressed between two machined surfaces. This sealing system on the quenching element is the most commonly used in the oil and gas industry where economics play a key role in purchase decisions. The gasket arrangement meets all code requirements, is easy to manufacture, and these cost savings can be passed on directly to the end user. The compression seal is more than adequate for low-pressure lines carrying volatile vapors. The ILSF-B is the best buy for a general all around Detona-tion arrestor with a removable quenching (Offset Dual Flange)The OSDF incorporates dual fl anges on the fl ame quenching element section to ensure that the proper gasket can be installed to accommodate critical conditions.

8 The dual fl ange arrangement also remains intact during a severe continuous burn condition where the downstream side of the Detonation arrestor gets red hot and can suffer from heat warping and distortion. On the dual fl ange Detonation arrestor , the upstream fl anges are not subjected to the elevated heat so they remain intact and functional, keeping critical piping OSDF is manufactured with the inlet and outlet offset. This allows travelling fl uids to pass through the bottom of the detona-tion arrestor and carry on down the piping. The element section remains dry and fully open, allowing the least amount of pres-sure drop and the maximum fl ow to pass through the unit. The OSDF can be installed vertically,horizontally or on a 45 angle. The OSDF incorporates a thicker continuous burn grid (than inline models) to ensure the maximum safety window for personnel to react, or for the condition to change and cease. The OSDF also offers superior fl ame front stoppage at elevated operating pressures.

9 This rugged design is unmatched in the OSDF is the top end of the Tornado family of Detonation Arrestors . Generally they are installed in petrochemical plants, refi neries or in critical conditions that require the best equipment you can buy. It is hard to defi ne value when you are consider-ing the personnel and the equipment these devices are (Offset Single Flange)The Offset Single Flange incorporates all the working features of the OSDF except it utilizes single instead of dual fl anges on the element section. It is manufactured with a machined gasket face on the element section. The main benefi t is economics. Certain applications call for exotic metals such as Hastelloy or Tantalum to be used for chemical attack corrosion resistance. Large diam-eter fl anges of these materials can be very expensive and the OSSF reduces costs. Some integrity is lost in the bolting system, but in most of these applications they are monitored closely. The OSSF gives you superior performance at an applicable Arrestors - ModelsTORNADO Technologies Inc.
