GAS CONTROL VAREC 9 Series IN-LINE DETONATION FLAME ARRESTER The 9 Series In-Line Detonation Flame Arreresters are designed for installation in piping systems to provide explosion protection. Introduction The 9 Series In-Line Detonation Flame Arresters are tested for actual field conditions not mandated by existing standards, including momentum impulse (long run stable detonation), thermal failure and re-ignition of downstream unburned gases providing maximum protection against all modes of flame propagation. Techincal Data TEST PROTOCOL Tested in accordance with the United States Coast Guard CFR 1. PROTECTION Bi-directional. Quenches deflagrations, stable and overdriven detonations regardless of piping configuration. Complete testing through the flame profile curve. INSTALLATION The Series 9 can be installed in the vertical or horizontal position. PASSIVE OPERATION Completely self-contained with no reliance on power supplies, sensors, actuators or any external components. MULTIPLE ELEMENT DESIGN Elements easily removed, separated and cleaned in the field. MECHANICAL DESIGN Standard construction is carbon steel housing fabricated in accordance with ASME/ ANSI with 1 R.F. line flanges. Elements are 316 stainless steel. Optional Features Arrester housing fabricated in 316 SS Class 3 ANSI R.F. or DIN mating flange connections Instrument and drain connections Special alloy fabrication and internal coatings Special surface finishes Special testing and designs Copyright 21 by Varec Biogas a Division of Westech Industrial Inc. 1
