Model 321 In-Line – Flame Arresters
Safety · Flame Arresters
The Storagetech Model 321 in-line detonation flame arrester (also referred to as a flame arrester or fire arrester) is designed for installation in gas pipelines. Detonation occurs when a flame traveling through the pipeline reaches supersonic speeds, typically as a result of pipeline configuration or surface roughness. Changes in gas density and pressure cause the flame velocity to transform from subsonic to supersonic. The flame arrester element is designed to have a surface area three to four times greater than that of the pipeline in which it is installed and is mounted between two flanged reducing spools. The element consists of one or more tightly wound spirals of corrugated stainless steel ribbon forming the passages through which the vapor flows. The area of each passage determines the level of protection provided by the element. The Storagetech Model 321 in-line detonation flame arrester has a Maximum Experimental Safe Gap (MESG) according to the standard and is suitable for gas groups IIB and IIA.
