Question 1

What information do you need to size and select a flame arrester or tank protection valve?

Accepted Answer

Sizing flame arresters and tank protection equipment requires a different set of inputs to safety relief valves. We work to API 2000 for tank venting and ISO 16852 for flame arresters. Send us the following with your enquiry: Tank or vessel details Tank type (atmospheric, low-pressure, API 650, API 620) Tank diameter, height, and total volume Operating temperature range Insulation status (affects fire-case sizing) Process / fluid Stored product (fluid name, vapour pressure, flash point) Vapour density relative to air Pumping rates (maximum in and out) Process temperatures during transfer Hazardous area / fire protection (flame arrester) Gas group classification (IIA, IIB, IIC) MESG (Maximum Experimental Safe Gap) of the medium Required application: in-line (deflagration or detonation) or end-of-line Distance from potential ignition source Pipe diameter and configuration Venting capacity (tank protection) Normal breathing requirement (pump-in / pump-out rates) Thermal in-breathing (cooling) and out-breathing (heating) demand Emergency vent requirement (fire case per API 2000) Acceptable pressure and vacuum limits Mechanical and installation Connection size and rating (flange, ANSI/AS/DIN) Orientation (vertical, horizontal) Material specification (body, screen, element) Required certifications (ATEX, USCG, FM, IECEx) Once we have this, we'll work through the sizing calculation, recommend a suitable flame arrester or vent from our manufacturer range, and confirm availability and lead time. The end user (process or plant designer) remains responsible for confirming the final selection against the application's design basis per AS 1210.
