Replacing the Deflagration Vent Plate

A deflagration vent is a safety device designed to protect equipment and buildings from the destructive pressure of a deflagration (a type of explosion) by providing a controlled pathway for the release of expanding gases, flames, and unburned material. It's a crucial component of explosion protection systems, particularly in industries handling combustible dust.
