Protectoseal is one of the world’s leading manufacturers in flame arresters for tanks and process lines, with a track record of over a century focused on safety against flame propagation and control of flammable vapours. Its offering is based on a very clear principle: allowing gas to pass during normal operation and stopping the flame front in the event of ignition, preventing the flame from reaching the tank, vessel or upstream installation. This function is critical in plants where the vapour-air mixture may fall within the flammable range and where an external or internal ignition would have direct consequences on asset safety and operational continuity.
Protectoseal’s flame arrester range covers end-of-line deflagration, in-line deflagration and in-line detonation configurations, allowing the solution to be adapted to the distance from the potential ignition source, type of service and expected flame behaviour. Correct selection does not depend solely on diameter or flow rate: it requires consideration of gas group, operating pressure and temperature, vapour composition, admissible pressure drop and the exact location of the equipment within the installation.
In addition to their protective function, flame arresters form part of a broader tank protection architecture, in which their integration with pressure/vacuum valves, emergency vents or inerting systems directly influences the overall vapour space behaviour. Protectoseal therefore adds value not only through the equipment itself, but through its ability to incorporate it within a complete protection solution.
