45000E/ 46000E Series In-Line Deflagration Flame Arresters, ATEX / CE / ISO

Protectoseal Series 45000E and 46000E In-Line Deflagration Flame Arresters are designed to withstand low, medium and high pressure deflagrations (subsonic). These arresters are bi-directional and capable of stopping a flame approaching from either direction in a piping system and can be mounted vertically or horizontally in the pipeline. Suitable for varying distances from the unprotected side of the vent pipe, maximum distance (Lu/D=50), and within determined operating pressure, consult factory for specifics. These arresters prevent confined deflagrations from passing the arrester and entering a protected area.

• Bi-directional design stops a flame approaching from either direction in a piping system
• Crimped metal arrester element minimizes pressure drops and reduces overall weight
• Straight through flow pattern minimizes arrester element fouling and simplifies the cleaning process
• Removable and interchangeable arrester element facilitates ease of inspection and maintenance
• High strength, welded steel housing hydrostatically tested at 235 PSIG
• Pressure retaining housing components are welded in accordance with ASME Pressure Vessel Code, Section IX requirements
