What is a flashback arrestor?

A flashback arrestor is safety device used on oxy-fuel systems to prevent a flashback from travelling into upstream equipment, such as gas cylinders. Without flashback arrestors installed, the operator and nearby personnel and equipment are exposed to the risk of explosion in the event of a flashback.

 

How does a flashback arrestor work?

In the event of a flashback, a flashback arrestor will prevent any reverse flow of gas and will also block the flame and prevent it from penetrating further upstream.
