The Series 670/6670 Flame Arresters are designed to provide flame stopping protection for a tank’s vapor space when mounted to the end of a tank nozzle leading directly to atmosphere.The arresters are intended for use with vapors equivalent to Group D of the National Electric Code (NEC 500).The arresters prevent a flame front generated by an unconfined deflagration occurring outside the tank from propagating into the vapor space.

TECHNIQUE

The arrester is mounted on the end of a vent pipe from the tank. Vapors are allowed to escape into the atmosphere and air can be drawn into the tank through the specially designed flame arrester grid assembly. If an ignition source outside the tank is encountered, the flame arrester provides protection for the tank contents.

SPECIAL FEATURES

Easy Inspection, Installation and Maintenance. Design and light weight of unit permit easy, convenient handling for inspection, installation and maintenance. The weather hood is readily removable by loosening just a few extra large wing nuts. Automatic Condensate Drainage. Vertically mounted, circular plate-type flame arrester is employed for self-drainage of condensate. This prevents accumulation of condensate subject to freezing and consequent clogging of the arrester under low temperature conditions.

Positive Flame Arresting. The Series 670/6670 employs a circular-plate, precisely-spaced, type flame arrester to protect tank contents by preventing the propagation of fire into the tank. Precision embossings on alternate plates provide correct air-spacing for flame arresting function. Plates are fabricated from 1/16" to 3/32" heavy gauge metal, depending on material of construction, to resist distortion and bending during cleaning.
