Flashback arrestor for lpg cylinder, Flashback arrestors (FBA) with flame arrestor IBEDA as a manufacturer provides a wide range of flashback arrestors (safety devices with flame arrestors). Through the combination of established safety elements, flashback arrestors provide protection against flashbacks and backfire. The flashback arrestors (FBA) can be used on single cylinders (regulator mounted), torches as well as on cutting machines. They prevent dangerous reverse flame propagation—commonly known as "flashback"—from reaching the gas cylinder or storage tank. Flashback: When a backfire takes place in a mixing chamber, unless you shut off the oxygen valve, the flame burning in the torch head may ignite gases in the hoses and result in a flashback. A flashback is an explosion that progresses through the torch, hoses, regulators, and into the cylinders. They incorporate a number of features designed to protect upstream equipment from damage in the event of a flashback or sustained burn back. A flashback arrestor for LPG (liquefied petroleum gas) is a critical safety device designed to prevent the reverse flow of flame into gas supply lines, which could otherwise lead to explosions or equipment damage. Feb 19, 2026 · Flashback arrestors are critical safety devices in any LPG system, especially those integrated with diesel engines. When a flashback occurs, the flame burns rapidly ‘upstream’, generally causing a loud explosion. Discover CE-certified LPG flashback arrestors in brass for welding & cutting. Flashback arrestors have to be tested for gas non-return, for tightness and for gas flow by a qualified person depending on the country specific regulations. An easily re-settable pressure control stops gas flow in the event of reverse flow or a flash-back that creates 10 psig back pressure. If un-checked it can continue through the torch into hoses, regulators and gas bottles/cylinders. Flashback arrestors or flame arrestors also prevent the formation of dangerous gas mixtures within the pipeline. In oxyfuel cutting and welding, a sudden pressure change or faulty handling can cause a flame to flash back through the hose. What is a Flashback Arrestor? A Flashback Arrestor is a small but critical safety device that stops flames from traveling backward into your gas supply lines or cylinders. Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks for pipeline outlets and single cylinders with high-consumption users The flashback arrestors are suitable for most technical gases (fuel gases) such as acetylene, hydrogen, methane, propane, propylene and butane as well as oxygen and compressed air. Same and Next Day Delivery. Trusted safety solution for oxygen, acetylene, and LPG systems. Of importance, all regulator end models incorporate a thermal cut-off valve as a failsafe, to shut off the flow of gas, eliminating the fire. Causes that can trigger a flashback include: Worn or improperly maintained Equipment, Operator Error, improper monitoring of cylinder pressures, and many o Choose from our selection of flashback arresters in a wide range of styles and sizes. This feature alerts the user that a reverse flow or a flashback of greater than 10 psig has occurred. Furthermore, it is the ideal protection at cylinder regulators, distribution lines, tapping points and gas distributors .
