End Of Line Deflagration Flame Arresters, CNC540

Motherwell Tank Protection Deflagration In-Line Flame Arresters are certified compliant with European ATEX and PED directives where applicable.

Motherwell Tank Protection can supply different types of end of line deflagration arresters, suitable for a wide variety of industries and applications. EVA, EVB, and AVC arresters have replaceable elements and are suitable for IIA, IIB3, and IIC gas groups respectively. SV and SVE arresters are small, light-duty arresters with fixed elements, whilst FE-IE arresters are for use with pressure and/or vacuum relief valves.

End-of-line deflagration arresters are designed to be installed at the end of a pipeline or exit vent from a vessel, where the ignition source is external, to provide protection against atmospheric deflagration.

We offer a series end-of-line deflagration arresters specifically designed to be used in conjunction with pressure/vacuum relief valves, to prevent propagation of flames in gas or vapour mixtures. These arresters are specifically designed to be located below the inlet of a pressure/vacuum relief valve, thereby providing an extra layer of tank protection.

APPLICATION

These end of line units are designed to be used as a venting device for installation at the end of a pipeline or exit vent on a vessel. They allow for an unrestricted flow of gases into the atmosphere and clean air into the tank/pipe therefore preventing possible vacuum conditions whilst ensuring protection to the vessel from any possible atmospheric deflagration.

PRINCIPLE OF OPERATION

An ‘end of line’ unit is designed to prevent an unconfined deflagration in the surrounding atmosphere from entering the pipe or system and is not suitable for preventing a flame from within the pipe or system igniting the surrounding area.
