An oxygen flashback arrestor is a safety device used in oxy-fuel welding and cutting to prevent the flame from traveling back up the oxygen hose and into the regulator or cylinder. This can happen if the flame is extinguished while the oxygen is still flowing, or if there is a leak in the hose. A flashback arrestor will stop the flame and prevent an explosion.
Flashback arrestors are typically made of sintered stainless steel or coiled tubing. The sintered steel arrestors have a honeycomb structure that absorbs the heat of the flame, while the coiled tubing arrestors use the heat of the flame to ignite a small amount of fuel gas, which then burns back upstream and extinguishes the flame.
Flashback arrestors are an essential safety device for anyone who uses oxy-fuel welding or cutting equipment. They are relatively inexpensive and easy to install, and they can save lives.
Here are some of the benefits of using an oxygen flashback arrestor:
- Prevents explosions. A flashback arrestor can prevent an explosion by stopping the flame from traveling back up the oxygen hose and into the regulator or cylinder.
- Protects equipment. A flashback arrestor can protect equipment from damage by preventing the flame from reaching the regulator or cylinder.
- Increases safety. A flashback arrestor can increase safety by reducing the risk of an explosion or fire.
If you use oxy-fuel welding or cutting equipment, it is important to use an oxygen flashback arrestor. They are an inexpensive and easy way to improve safety and protect your equipment.
Here are some safety tips for using an oxygen flashback arrestor:
- Always install the flashback arrestor in the correct orientation. The arrestor should be installed with the flame arrestor element facing the torch.
- Inspect the flashback arrestor regularly for damage. If the arrestor is damaged, it should be replaced.
- Do not use a flashback arrestor that is past its expiration date. The expiration date is usually stamped on the arrestor.
By following these safety tips, you can help to ensure that your oxygen flashback arrestor is working properly and that you are using it safely.
