Flame Arrestors
DETONATION FLAME ARRESTERS
The TELEFLO make Deflagration & Detonation Flame Arrester inhibits flame propagation in gas piping systems. The design of the Model fflame Arrester makes it ideal to protect
liquid storage tanks containing both NEC Group D and Group C vapors (IEC Class IIA and IIB1 through IIB3 vapors) with a Maximum Experimental Safe Gap (MESG) equal to or greater than 0.026″ [0.65 mm].
HIGHLIGHTS
- Sizes 2" through 12" (50-300 mm)
- Available in carbon steel, stainless steel, Hastelloy C, and other materials
- Wafer mesh element design for quick and easy maintenance
APPLICATIONS
Models are available in flange sizes from 2″ through
12″ (50 – 300 mm) for the following applications:
- In-line or end-of-line deflagrations in any piping configuration
- Stable detonations in any piping configuration
- Unstable detonations in any piping configuration (element sizes <=12")
- Pre-ignition system pressure up to 19.7 psia (1.36 bara) (see specifications table)
- Bi-directional with respect to flow and ignition source
- Factory installed integral flame sensors are available
Housings are available in carbon steel, 316SS, and HASTELLOY C and elements in 316SS,
HASTELLOY C, and other corrosion resistant alloys.
These arresters are compact with high flow capacity and low pressure drop. Elements are easily
removed in-line for cleaning and maintenance and are economical to replace if necessary.
Contact the factory for additional features and options.
