Model No: 321
Storagetech’s Model 321 In-line Detonation Flame Arrestor (also called flame arrester or fire arrestor) is designed for installation in gas pipelines. Detonation occurs when a flame traveling through the pipeline reaches supersonic velocities, usually as a result of the pipeline configuration or pipeline surface roughness. Changes in gas density and pressure cause the flame velocity to metamorphose from subsonic to supersonic.
The flame quenching element is designed to be three or four times the area of the pipe in which it is installed, and is assembled between two flanged reducing spools. The element comprises a tightly rolled scroll or scrolls of crimped stainless steel ribbon to form passages through which the vapour passes. The area of each passage determines the level of protection that the element provides. Storagetech’s Model 321 In-line Detonation Flame Arrestor has a maximum experimental safe gap (MESG) as per the standard and is suitable for gas groups IIB and IIA.
