In-Line Deflagration Flame Arresters, ATEX / CE / ISO

Series No. 45000E / 46000E

Gas Groups:
45000E – IIA | D
46000E – IIA, IIB3 | D, C 

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. 

 

Description

  • 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

“We worked with the technical expert at Protectoseal on the design of the pressure protection and control systems for the reactors, vessels and tanks in the new plant. I was very impressed with their technical knowledge of the applicable codes, the products and the way they worked with us to make sure that our specific processes, materials and operating situations were fully understood.”
