TT1200 Flame Arrester

A flame arrester installed on the tank’s vent line can prevent explosions by stopping flames from entering the tank and igniting the flammable gases inside. Flame arresters can also be used in gas pipelines and other equipment that handle flammable gases or liquids to prevent explosions or fires from spreading to other parts of the system.

Additional information


TT1200 Series flame arrestor is a type of flame arrestor and explosion arrestor, which is installed at the end of the pipe or near the end of the pipe, or on top of the tank to stop the flame from spreading at subsonic speed.

Design Features of Flame Arrester

  • Size: 2″~12″ (DN50~300).
  • Unique corrugated flame arresting cores.
  • Low flow resistance, double flame arrestor core setting.
  • Easy to clean, easy maintenance, two-way flame arrestor.
  • Suitable for storing Class A oil with flash points lower than 28℃ and Class B oil with a flash point lower than 60℃, such as gasoline, toluene, kerosene, crude oil, etc. on vertical storage tanks and petrochemical Pipeline use.
  • According to user needs, the functional structure of the jacket, purge hole, inspection hole, etc. can be added.
  • Flange standards according to ANSI B16.5, HG series, GB series, SH series, JIS series, and EN series can be selected according to the requirements of the end-user.

Here are some of the most common types of flame arresters:

  • Deflagration flame arresters: These are the most common type of flame arresters, designed to stop flames that propagate at subsonic speeds. They work by breaking up the flame front and cooling the flammable mixture, preventing it from igniting.
  • Detonation flame arresters: These are designed to stop detonations, which are supersonic flame fronts that can cause significant damage. They work by creating turbulence in the flammable mixture, which dissipates the energy of the detonation and extinguishes the flame.
  • End-of-line flame arresters: These are used to protect the end of a pipeline or vent, preventing flames from escaping into the atmosphere. They are often used in storage tanks and vessels.
  • In-line flame arresters: These are installed inside a pipeline or vessel to prevent flames from spreading to other parts of the system.
  • High-pressure flame arresters: These are designed to withstand high pressures, typically used in oil and gas processing facilities.
  • Low-pressure flame arresters: These are designed for low-pressure applications, such as storage tanks and fuel dispensers.
  • Liquid flame arresters: These are used to prevent explosions or fires in tanks containing flammable liquids, such as gasoline or chemicals.

The selection of the type of flame arrester depends on the specific application, the type of flammable substance, and the operating conditions.
