Flame Arrestor In Gas Welding, Same and Next Day Delivery. Flashbacks occur when a flame travels backward into the gas supply system, often originating from the cutting or welding torch. Part 1: Incorporating a flame (flashback) arrestor. a flame arrestor which quenches the flame front. Choose from our selection of flame arresters in a wide range of styles and sizes. Protect regulators and gas cylinder against flashback and detonation. 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. Dec 14, 2025 · Oxyfuel gas processes, such as welding, cutting, and brazing, involve mixing fuel gas and oxygen, creating a significant risk for fire and explosion hazards. Its durable construction and combined flame arrestor and non-return valve ensure safe, dependable performance when mounted directly at the torch. It protects the user and equipment from damage or explosions. WITT is a high-quality manufacturer of gas safety and gas control equipment. This is the major reason for using other fuel gases such as MAPP, propylene, propane, and natural gas which may be safely used at higher operating pressures. Mar 30, 2021 · When a flammable mixture of fuel gas and oxygen or air is present in a gas line upstream of a welding or cutting blowpipe, flame can travel backwards in the form of flash back into the gas line, and there is the possibility of a serious accident. WITT flashback arrestors or flame arrestors are used to protect single cylinders, outlet points or pipelines and can be used for almost all technical gases such as acetylene, propane, propylene, ethylene, methane, hydrogen or oxygen. These indispensable safety devices provide reliable protection during oxyfuel welding, cutting and related processes. When more than 15 pounds of pressure is used, acetylene becomes unstable and decomposes explosively. Feb 10, 2026 · Flashback arrestors for gas welding equipment needed to meet ISO 5175-1:2017 safety device requirements and tests, while Australia required conformity to AS4603 and compliance support under AS4839 for portable and mobile oxy-fuel gas systems. Safety devices. 5 days ago · For sale is a brand new set of 2 flashback arrestors (gas fuses / individual fuses) from Borris. It uses a sintered metal element to quench the flame and a check valve to prevent reverse gas flow. Gas can flow through the arrestor ‘filter’, but good thermal conductivity and high porosity of the sintered metal elements of the ‘filter’ lead to flame quenching. The product range includes gas mixers, gas analysers, package leak detection equipment as well as flashback arrestors and non-return valves made of brass and stainless steel, safety relief valves, dome pressure regulators, gas filters and quick couplers. It is widely used in fabrication workshops, metal cutting operations, maintenance facilities, and industrial environments where safe gas control is essential. The FT Type flashback arrestor is classified as a non-resettable safety device and is specifically designed for oxygen service in oxy-fuel welding and cutting systems. . One cause of fires and explosions is high acetylene pressure. No. A flashback arrestor is a safety device designed to stop a flame in its tracks. Jun 11, 2024 · What is a flashback arrestor? In contrast to the check valve's uni-directional flow control, the flashback arrestor serves a more specialized purpose: preventing and mitigating the risk of flashback incidents. It prevents flashback by cooling the flame to below the ignition temperature of the gas or gas mixture. The Wescol Type 84 (T84) Torch Mounted Oxygen Flashback Arrestor provides reliable protection against uncontrolled combustion in oxyfuel applications. 1 Choice for Flame Arrestors (Flashback Arrestors) certified and under surveillance by The Federal Institute for Materials Research and Testing (German: Bundesanstalt für Materialforschung und -prüfung, or BAM) and OCIMF/RIGHTSHIP compliant. Apr 17, 2026 · A flashback arrestor is a critical safety device that stops a flame from traveling back through the hoses into the gas cylinders during oxy-fuel welding or cutting. Flashback arrestors are safety devices mandated by federal occupational standards to prevent flame propagation from traveling back Gas welding equipment. They effectively prevent dangerous gas leakage or flame flashback into the hoses and pressure reducers, which significantly increases occupational safety on the welding system. Discover flame arrestor price deals with CE-certified brass & stainless steel models for gas pipelines, cutting torches, and industrial use. This combination of high-pressure gases and a working flame necessitates specialized protective equipment.
