CE in-line detonation flame arrestor

Request this configurationChat on WhatsApp

The CE flame arrestor is described for detonation duty and in-line installation. It is used where a deflagration arrestor cannot be installed as close to the ignition source as the process requires. The internal element divides the flow path and removes heat to limit flame propagation. The listed range is DN15–DN200, with flanged or threaded connections and a stainless-steel element. Select body material, gas composition, pressure, temperature and installation position for the hazard scenario; a historical design reference is not a current product certificate.

FE in-line deflagration flame arrestorType: FE · Protection duty: Deflagration · Installation: In-line · Size range: DN15–DN500 · Application: Near the potential ignition source on a straight pipe portion without elbows or valvesType FE is described for near the potential ignition source on a straight pipe portion without elbows or valves. Its protective duty is deflagration and its installation arrangement is in-line; establish the hazard and mounting position before selection. The listed size range is DN15–DN500. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
FE end-of-line deflagration flame arrestorType: FE · Protection duty: Deflagration · Installation: End of line · Size range: DN15–DN500 · Application: Tank protection against deflagration from an external ignition sourceType FE is described for tank protection against deflagration from an external ignition source. Its protective duty is deflagration and its installation arrangement is end of line; establish the hazard and mounting position before selection. The listed size range is DN15–DN500. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
MB gas-sampling flame arrestorType: MB · Protection duty: Deflagration · Installation: In-line / End of line · Size range: NPS 1/8–1 1/2 · Application: Gas-analysis and sampling equipment and small-diameter pipingType MB is described for gas-analysis and sampling equipment and small-diameter piping. Its protective duty is deflagration and its installation arrangement is in-line / end of line; establish the hazard and mounting position before selection. The listed size range is NPS 1/8–1 1/2. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
SV end-of-line flame arrestorType: SV · Protection duty: Deflagration · Installation: End of line · Size range: NPS 3/8–2 · Application: Natural-gas or diesel-engine duty as additional equipment to a safety valveType SV is described for natural-gas or diesel-engine duty as additional equipment to a safety valve. Its protective duty is deflagration and its installation arrangement is end of line; establish the hazard and mounting position before selection. The listed size range is NPS 3/8–2. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
LE liquid-service siphon flame arrestorType: LE · Protection duty: Detonation · Installation: In-line · Size range: NPS 1/2–3 · Application: Discontinuous flammable-liquid flow, preventing vapor ignition between batchesType LE is described for discontinuous flammable-liquid flow, preventing vapor ignition between batches. Its protective duty is detonation and its installation arrangement is in-line; establish the hazard and mounting position before selection. The listed size range is NPS 1/2–3. Specify materials, connections, fluid composition, ignition-source distance and permissible pressure drop for this configuration. Qualification for one flame-arrestor duty must not be assumed to cover another hazard or installation arrangement.
