I. INTRODUCTION
Groth
Corporation’s flame arresters are designed to inhibit flame propagation in gas piping systems
and to protect low pressure tanks containing flammable liquids. They protect low flash point liquids
from externally caused sources of heat and ignition, providing increased fire protection and safety.
The flame arresters consist of two main components, the arrester bases and the flame element
housing. The bases serve as the connecting interface to the piping system. The housing
accommodates the flame element and is instrumental in stopping the flame passage. The depth of the
flame element absorbs the heat from the vapor flow, cooling the vapor to prevent auto-ignition on the
protected side.
The flame element is comprised of small parallel triangular passageways aligned so that an
approaching flame front is slowed down and then quenched before it can propagate to the protected
side of the device.
Model 7618 and 7628 flame elements utilize spiral wound, crimped ribbon constructed of corrosion
resistant materials, to insure the best flame quenching performance with minimum pressure drop.
Depending on the design of the system in which it is used, the arrester bases can include optional
ports for temperature or pressure monitoring devices. These devices can activate warning or
shutdown systems if abnormal conditions are detected.
A flame arrester should be treated as a safety device and maintained by a knowledgeable repair
technician. Carefully read and understand this Manual before installing or servicing this product.
