Flame arrestors are safety devices used to prevent the spread of flames in flammable gases and liquids and to prevent backfire-induced explosions. They are typically employed in the following scenarios:
(1) Pipelines transporting flammable and combustible gases;
(2) Oil tanks for storing petroleum and petroleum products;
(3) Ventilation outlets of systems with explosion risks;
(4) Oil vapor recovery systems;
(5) Gas networks for combustion in regenerative furnaces;
(6) Exhaust systems of internal combustion engines;
(7) Torch systems.
They are suitable for storing petrochemical products with a flash point below 60℃, such as gasoline, kerosene, light diesel, and toluene.
Operating temperature ≤ 180℃
Shell material: carbon steel, aluminum alloy, stainless steel: SUS304, SUS304L, SUS316, SUS316L
Flame arrestor core material: stainless steel corrugated plate.
Explosion-proof grade: BS5501: IIA, IIB, IIC.
Operating pressure: 0.6MPa - 5.0MPa, high pressure requires customer specification.

Explore Our Flame Arrester Products
Our comprehensive catalog features various safety solutions tailored to different operational demands. Whether you require localized protection or heavy-duty network safeguarding, our flame arrester products deliver uncompromising performance. They ensure reliable operation in critical environments.
Pipe Flame Arresters
Designed for localized pipe protection, our pipe flame arresters are ideal for standard industrial applications. We construct these units from durable materials like stainless steel and carbon steel. This ensures excellent corrosion resistance and longevity. They seamlessly integrate into existing piping networks. As a result, they provide a reliable barrier against accidental vapor ignition without restricting normal gas flow.
Pipeline Flame Arresters
For complex industrial networks and high-pressure environments, our heavy-duty pipeline flame arresters offer robust protection. We specifically design these advanced units to handle continuous flow conditions. They effectively mitigate risks associated with volatile gas mixtures. By utilizing precision-engineered internal elements, they quench flames rapidly. This keeps even the most demanding chemical and petrochemical processing facilities safe.
Flame Arrestor Working Principle & Technical Specifications
Understanding the technical mechanics behind vapor control helps you select the right safety equipment. Our engineering team designs each unit to meet rigorous international standards. We prioritize effective flame quenching, heat dissipation, and pressure management.
How Does a Flame Arrester Work?
The core function of these safety devices relies on a highly engineered permeable matrix. We typically construct this as a crimped metal ribbon element. When a gas mixture ignites, the resulting flame travels through the piping until it reaches this matrix. The narrow channels of the crimped ribbon absorb and dissipate heat rapidly. This drops the temperature below the ignition point. Ultimately, it extinguishes the fire before it can spread further.
Deflagration vs. Detonation Arresters
Choosing the correct equipment depends on the speed and pressure of the potential flame front. A deflagration involves subsonic flame propagation. This can be safely managed by an in-line deflagration flame arrestor placed near the ignition source. In contrast, a detonation involves supersonic flame speeds and massive pressure shockwaves. For these extreme conditions, a robust in-line detonation flame arrestor is required. It withstands the mechanical impact and quenches the high-velocity flame.
In-Line vs. End-of-Line Configurations
Installation location dictates the structural configuration of the arrester. In-line models are installed within enclosed piping systems. They prevent flames from traveling between different sections of a facility. End-of-line units are designed for atmospheric tank venting. We install them at the end of a vent pipe. This prevents external flames, such as those from a lightning strike, from entering the storage tank.
Download Flame Arrester Sizing & Selection Guide
Proper sizing is critical to ensure maximum safety. It prevents unacceptable pressure drops in your system. We offer a comprehensive, downloadable PDF guide tailored for B2B engineers and procurement managers. This resource includes detailed sizing charts and vapor control data. It also provides complete technical specifications to help you specify the exact model. Accessing this guide will streamline your procurement process and ensure compliance with industry safety standards.

Frequently Asked Questions (FAQ)
What is the difference between a flame arrestor and a breather valve?
A breather valve regulates pressure and vacuum in a storage tank. Meanwhile, a flame arrestor prevents external flames from entering the tank. We often recommend using them together for comprehensive tank safety and vapor control.
Do you offer custom pipeline flame arresters?
Yes, NIPO provides non-standard customization for pipeline flame arresters. Our elite engineering team can design solutions tailored to your specific pressure, material, and sizing requirements.
How often should a flame arrestor be inspected?
We recommend inspecting these safety devices at least annually. Highly corrosive or dirty environments require more frequent checks. Regular maintenance ensures the internal element remains clear and functions correctly during an ignition event.
