Evitar detonaciones en tuberías

Los apagallamas a prueba de detonaciones estánn diseñados para evitar la propagación de la llama en sistemas de tuberías donde la combustión puede transformarse en una detonación de alta energía. 

A diferencia de las deflagraciones, las detonaciones implican velocidad supersónica de la llama and significant pressure waves, requiring equipment that can withstand and safely dissipate these extreme conditions. In industrial systems handling flammable gases or vapors, Detonation Arresters are typically installed within pipework to protect downstream equipment, storage tanks, and process units. Their function is to suppress the effects of a detonation, extinguish the flame, and protect non-explosion-proof components and vessels within your system.

How it works

Working principle of Flame Arresters

When a detonation reaches the arrester, the flame and shock wave enter the narrow gaps of the FLAMEFILTER® discs. The energy is dissipated within these gaps, which cools the flame below its ignition temperature Température d'allumage Lowest temperature (of a hot surface) at which ignition of a flammable gas or vapor in a mixture with air or air/inert gas occurs under specified test conditions. and extinguishes it. This prevents the flame front from continuing through the pipeline. 

For larger nominal diameters, additional design elements such as the patented SWGTE (Shock Wave Guide Tube Effect) reduce the energy of the detonation shock wave before it reaches the flame arrester unit Flame arrester unit Flame arrester casing with FLAMEFILTER® set. . This staged energy reduction improves the reliability of flame extinction under high-energy conditions and improves process efficiency.

Available Options

We provide engineered safety solutions.

Since 1954, PROTEGO® has built and provided Flame Arresters, Pressure and Vacuum Relief Valves Soupape de surpression et dépression A pressure and vacuum relief valve is a pressure equalization valve for impermissible pressure and vacuum in a closed system. and Tank Equipment, now with the help of more than 750 employees worldwide.

Engineering and Compliance

PROTEGO® Detonation Flame Arresters are type-tested and certified according to ATEX and other international standards. Each device is supplied with a statement of conformity defining its approved operating conditions.

Selection is based on key engineering parameters:

Stable or unstable detonation
Gas/vapor or liquid service
Operating pressure / temperature 

If no suitable device can be found, please contact us. Special designs and approvals are available.

Sizing is based on the relationship between flow rate and pressure drop using the p/V performance diagram.

Nominal diameter
To select nominal diameter: use flow rate and allowable pressure drop
Pressure drop
To estimate pressure drop: use flow rate and diameter

Key Features and Design Characteristics

Multiple FLAMEFILTER® discs arranged in a defined geometry create controlled narrow gaps for flame quenching Extinction Refroidissement d’un fluide par addition d’un autre fluide à température inférieure. . This ensures reliable extinction of detonations under specified process conditions.

All dry PROTEGO® Detonation Flame Arresters use a modular design. This simplifies servicing and allows configuration based on application-specific parameters such as pressure, temperature, and gas properties.

For larger nominal diameters, the patented Shock Wave Guide Tube Effect reduces detonation energy before it reaches the flame arrester unit. This improves protection performance in high-energy detonation scenarios, reducing pressure drop and improves process efficiency.

Devices are designed for stable and unstable detonations and are also tested for deflagration protection. With an additional temperature sensor Sonde de température Temperature sensor for monitoring the temperature. , they can respond to short-time stabilized burning conditions.

Configurations are available for dry gas and vapor systems as well as liquid systems using a liquid barrier. Selection is based on operating conditions, explosion group classification, and process characteristics.

Designs are available in concentric, eccentric, and 90-degree configurations. This allows integration into different piping layouts and system geometries, improves device maintainabilty and helps with challenging conditions such as condensate carryover.

A wide range of sizes, materials, and designs can be provided. If standard configurations are not suitable, custom solutions can be developed and tested at the PROTEGO® test facility.
