Bi-Directional Detonation Flame Arresters – ATEX / CE / ISO

Bi-Directional Detonation Flame Arresters – ATEX / CE / ISO

Series No. 26000E / 36000E

Gas Groups:
IIA, IIB3 | D, C

Protectoseal Series 26000E / 36000E Detonation Flame Arresters are designed to withstand confined deflagrations, stable detonations and overdriven (unstable) detonations. These arresters are bi-directional, capable of stopping a flame or detonation approaching from either direction in long or complex piping runs such as those encountered in vapor recovery or manifolded tank systems. They can be mounted in any location in a piping system so long as initial temperature and pressure guidelines are followed.

Description

  • Bi-directional design stops a flame approaching from either direction in a piping system
  • Crimped metal arrester element minimizes 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 475 PSIG
  • Pressure retaining housing components are welded in accordance with ASME Pressure Vessel Code, Section IX requirements
