Product Introduction
In-line Detonation Flame Arrester
In long-distance transportation or complex-layout flammable gas pipeline systems, the highest level of flame propagation threat — stable and unstable detonation — requires the most top-level protection solution. The In-line Detonation Flame Arrester is the ultimate safety device designed for this purpose, representing the highest specification of flame arrester protection. Installed directly in series in the pipeline, it can reliably quench detonation flames propagating at supersonic speed accompanied by extremely high pressure, serving as the last and most solid line of defense to protect critical process equipment and the entire pipeline network from catastrophic explosions.
Core Functions & Working Principle
This flame arrester is specifically designed for working conditions with detonation risks, such as long straight pipelines, multi-elbow pipe sections or complex pipe networks, where deflagration is likely to accelerate into highly destructive detonation. Its core adopts a high-strength, precision-calculated spiral-wound metal corrugated strip flame arrestor grid. When stable or unstable detonation occurs in the pipeline, the supersonic flame front and extreme pressure wave impact the flame arrester simultaneously. The unique flame arrestor grid structure instantly absorbs and dissipates the huge energy of the flame through its extremely large specific surface area, while decomposing and attenuating the explosion pressure wave. Based on the combined effect of quenching and pressure drop, it completely extinguishes the flame within milliseconds and prevents its continued propagation, thereby protecting upstream or downstream equipment.
Key Product Advantages & Customer Value
- Top-level Detonation Protection: Specifically designed to stop the most severe stable and unstable detonations, complying with strict standards such as ISO16852 and GB/T13347. It provides protection for gas groups IIA, IIB, and IIB3/C to cope with extreme working conditions.
- Excellent System Performance: The advanced flow channel design ensures maximum flow capacity and minimum permanent pressure drop while providing unparalleled safety protection, minimizing the additional impact on normal system operation and energy consumption.
- Extreme Durability & Maintenance-Friendly: The shell and flame arrestor grid materials can be selected from carbon steel, 304/316L stainless steel and Hastelloy, with excellent mechanical strength and corrosion resistance. Flange connection is adopted, allowing the flame arrestor grid assembly to be disassembled without cutting the pipeline, facilitating inspection, cleaning and maintenance, and achieving optimal total life-cycle cost.
- Comprehensive Design Features: Standard configuration includes a temperature detection port for easy system monitoring. The bidirectional flame arresting structure can resist detonation threats from any direction of the pipeline. Flange connections support global mainstream standards such as ANSI, DIN, and HG/T20592~20635-2009, enabling hassle-free integration.
- Proven Reliability: As a high-end product of the "FA-Det" series, its design has undergone strict theoretical calculations and physical verification (such as detonation resistance tests), ensuring foolproof protection performance under nominal working conditions and providing authoritative safety endorsement for your project.
Typical Application Scenarios
- Long-distance natural gas transmission pipelines or process gas pipelines.
- Complex flammable gas pipeline systems with multiple elbows, tees or diameter changes in chemical plants and refineries.
- Flare gas collection main pipes and discharge systems.
- Closed pipeline systems that may have the risk of deflagration-to-detonation transition.
- Any critical safety location that requires the highest level of flame arrestor protection.
