Deflagration lock for atmospheric explosions with flame propagation speeds below the speed of sound, gases/vapors classified in explosion subgroup IIA . Max. distance from potential ignition source 50D. Can be installed in pipelines and is also available in a pipe-end design.
Available sizes: DN15 – DN150 (larger sizes with collection structure)
Marking: Ex II 1 G IIA T6 (T5 also available for DN15 – DN80)
The F-R/2-07 type deflagration lock is a protective system designed to prevent the spread of flames or deflagration (explosion) at the installation site. The installation site is an environment or pipeline in which an explosive gas/vapor-air mixture may form.
The assembly provides protection against atmospheric explosions as a final safeguard. It can only be installed in systems where operating conditions that could cause short-term or sustained combustion on the assembly are unlikely to occur.
We manufacture F-R/2-07 type deflagration arresters in sizes NA15 – NA150.
