This is a further response to your memorandum of October 4, 1991, in which you sought guidance as to when flashback arrestors and backflow protective equipment are required in fuel-gas supply systems, in keeping with the requirements of 29 CFR 1910.253, Oxygen-fuel gas welding and cutting.

Safety device for torch or point of use (cutting machines) EN ISO 5175-1

Type: GG, GT, TT,DG-U, DG91UA

Highlights

• Welding up to 30 mm
• Flame cutting up to 500 mm
• Heating up to 100 mm

IBEDA offers flashback arresters with flame barriers and gas non-return valves (check valves). The flashback arresters GG, GT, TT and DG91UA are torch or point of use (i.e. cutting machines) flashback arresters that have the safety features of a flame barrier and a gas non-return valve (check valve), thus meeting the requirements of a flashback arrester described in EN ISO 5175-1.

The integrated flame barrier extinguishes the flashbacks and protects the valve to make sure it works safely even after a flashback. The flashback arrester model TT is a barb connection that installs a reverse flow check valve and flashback arrester in welding hose. The torch mounted or hose mounted flashback arresters prevent hazardous gas mixtures from harming the user. IBEDA offers flashback arresters for many industrial gases (Fuel gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.
