Flashback arrestors with different size and flow rate, and different connections. A flashback arrestor [1] or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions.
Flashback is the condition of the flame propagating down the hoses of an oxy-fuel welding and cutting system. To prevent such a situation a flashback arrestor is usually employed. [22] The flame burns backwards into the hose, causing a popping or squealing noise. It can cause an explosion in the hose with the potential to injure or kill the ...
Maximum experimental safe gap (MESG) is a standardized measurement of how easily a gas flame will pass through a narrow gap bordered by heat-absorbing metal. MESG is used to classify flammable gases for the design and/or selection of electrical equipment in hazardous areas, and flame arrestor devices. [1]
A flame arrester during testing A flame arrester made for a 91 cm (36 inch) pipe weighing 10 tons. A flame arrester (also spelled arrestor), deflagration arrester, [1] or flame trap [2] is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame.

This Detonation Flame Arrester is being tested for an 8-inch piping system at Brooker Laboratory Testing Company to the USCG 33cfr154.1325 Standard. Detonation Flame Arresters for various pipe sizes from Paradox Intellectual Inc. The largest detonation flame arrester ever built at the time, weighing 10 tons, for 30 inch pipe.
When studying or discussing explosive safety, or the safety of systems containing explosives, the terms deflagration, detonation and deflagration-to-detonation transition (commonly referred to as DDT) must be understood and used appropriately to convey relevant information.
A crack arrestor (otherwise known as a rip-stop doubler) is a structural engineering device. Being typically shaped into ring or strip, and composed of a strong material, it serves to contain stress corrosion cracking or fatigue cracking, helping to prevent the catastrophic failure of a device.
