Note: Flame arrestors are for use within 10 pipe diameters of the atmosphere. For installation more than 10 pipe diamters from the atmosphere, select the in line option.
Note: Choose deflagration for lower speed, short or moderate pipe runs with less than 50 pipe diameters distance from atmosphere. Choose detonation for supersonic shock waves with long pipe runs more than 50 pipe diamters from the atmosphere, or high risk process gases.

How to determine?
Match materials with the process fluid’s chemical compatibility and corrosion resistance using the product SDS, process conditions, and corrosion data. Consult engineering specifications or product catalog for available material options.
How to determine?
Look at your tank venting or process flow records under normal, steady conditions. If unavailable, your process engineer or flowmeter data will provide this.
How to determine?
Review pump transfer rates, maximum tank fill rates, or worst-case emergency venting scenarios. Operations or safety data sheets may have these numbers.
How to determine?
Check your system pressure gauge or P&ID diagrams. Tank vents are often measured in inches of water column (e.g., +2" WC).
How to determine?
Ask your process engineer or refer to tank/line specifications. If unknown, share your operating pressure range — we can recommend safe values.
How to determine?
Use a thermometer, temperature gauge, or process specification. If temperatures fluctuate, note both normal and maximum values.
How to determine?
Check your MSDS (Material Safety Data Sheet) or chemical process documentation. If unsure, list the main chemicals present.
How to determine?
Measure the pipe length between the arrester and the possible ignition point (e.g., flare, open flame, static source).
How to determine?
Use equipment specs (e.g., compressors, engines, burners). If unknown, describe the ignition source — we can estimate typical ranges.
How to determine?
Look at where you plan to install it — on top of a vent stack, inline with piping, or at an outlet. A photo often helps us verify.
How to determine?
Decide whether you need monitoring points (pressure, temperature, purge gas) connected to the arrester. If unsure, we can recommend based on your application.
How to determine?
Check if your process generates condensation or liquid carryover. If unsure, drains are usually recommended for safety.
How to determine?
Count the elbows or bends between the arrester and ignition source. If you don’t know, provide a sketch or piping layout.
