    The end-of-line flame arresters are designed to prevent unrestricted deflagration from the surrounding atmosphere from entering pipelines or systems. They are not suitable for preventing flames within the pipeline or system from igniting the surrounding area.

    Applications:

    • Ground flares

    • Hazardous chemical storage and transportation at terminals

    • Oil and gas recovery systems

    • Oil storage tanks

    • Gas pressure regulation systems

Model 6111 End-of-Line Flame Arrester

The Model 6111 End-of-Line Flame Arrester is installed at the end of a pipeline or the outlet of a storage tank (typically at the top). Equipped with an all-weather protective cover and flame arresting elements, it allows gases to freely vent into the atmosphere and clean air to enter the tank or pipeline. This prevents vacuum conditions and protects the storage tank or container from backfire, water ingress, or other foreign matter.
