End-of-Line Deflagration Flame Arresters
End-of-Line Deflagration Flame Arresters
Chemoil End-of-Line Deflagration Flame Arresters are engineered to prevent the propagation of atmospheric deflagration flames through vent openings, protecting storage tanks, process vessels, and vent systems handling flammable gases and vapors. Installed at the open end of vent pipelines, these flame arresters safely extinguish flames by dissipating heat through a precision-engineered crimped ribbon flame element, preventing ignition from reaching protected equipment while allowing unrestricted venting under normal operating conditions.
Manufactured from premium-grade stainless steel, carbon steel, aluminum, and corrosion-resistant alloys, Chemoil End-of-Line Deflagration Flame Arresters provide reliable performance in hazardous environments with low pressure loss and minimal maintenance. They are widely used in chemical plants, petroleum terminals, refineries, pharmaceutical facilities, biofuel storage, solvent handling systems, and tank farms, complying with international standards for explosion protection and flame arresting.
