Flame Arrester - Metal | Red Fire Fighting Application Flame Blocking Mesh Element

A flame arrester also known as a deflagration arrester or flame arrestor is a safety device designed to prevent the propagation of flames in equipment where flammable gases vapors or dust may be present. It is commonly used in industrial settings such as chemical processing plants oil refineries and storage tanks. The primary function of a flame arrester is to protect personnel equipment and the environment from the potentially catastrophic consequences of an uncontrolled combustion.

Key features and functions of flame arresters include:

1. **Preventing Flame Propagation:** Flame arresters are installed in pipes ducts or openings of vessels to stop the transmission of flames from the external environment to the interior or vice versa.

2. **Construction:** They typically consist of a metal housing with a series of metal plates mesh or other flame-resistant materials. The design of the arrester allows the passage of gases or vapors while inhibiting the progress of flames.

3. **Mesh Element:** Many flame arresters incorporate a mesh or perforated plate as the main flame-blocking element. This element disrupts the flame front and dissipates heat preventing the flame from continuing to burn.

4. **Installation:** Flame arresters are installed at locations where there is a risk of deflagration (rapid combustion). Common installation points include the openings of storage tanks pipelines and ventilation systems.
