KITO G 26.2.1 N – Bidirectional In-line Detonation Flame Arrester

The KITO® RG-Det4-IIA-…-4.5 / -4.5-T / -TT is a bidirectional in-line detonation flame arrester with flanged connections, designed for the protection of vessels and process equipment against stable detonation in piping systems conveying flammable gases, vapors, or liquids capable of forming explosive atmospheres. The device is tested and certified as a detonation flame arrester type 4 for bidirectional operation.

Operating Limits

  • Explosion groups: IIA1 to IIA
  • MESG: > 0.9 mm
  • Max. operating pressure: 4.5 bar abs.
  • Max. operating temperature: 60 °C
  • Endurance burning resistance: BT ≤ 1.0 min
  • Installation: horizontal or vertical piping

Connections and Materials

Available in DN 15, DN 20, DN 25, all rated PN 40, with corresponding ½", ¾", 1" connections. Standard flange: EN 1092-1 type B1; optional ASME B16.5 Class 150 RF.

Materials:

  • Body: carbon steel or stainless 1.4571
  • Gasket: HD 3822 or PTFE
  • KITO element: fully replaceable
  • Housing / mesh: 1.4301 / 1.4310 or 1.4571 / 1.4571
  • Bolts / nuts: A2 or A4

Thermal Monitoring

Variants -T and -TT are equipped with PT100 sensors, ¼" connection, stainless 1.4571. For stabilized burning detection, a sensor is required on each potentially exposed side. PT100 is for alarm/interlock only, not for actuation.

Application Selection

Select G 26.2.1 N for compact flanged detonation flame arresters in IIA media up to 4.5 bar abs. Selection must consider MESG, flow, pressure drop, gas density, temperature, gasket compatibility, and PT100 requirement. Flow curves are based on air ρ = 1.29 kg/m³ at 273 K.

Description

KITO® RG-Det4-IIA-…-4.5

KITO® RG-Det4-IIA-…-4.5-T (-TT)

– design with flange connection-

  • For installation into pipes to the protection of vessels and components against stable detonation of flammable liquids and gases.
  • Tested and approved as detonation flame arrester type 4.
  • Approved for all substances of explosion groups IIA1 to IIA with a maximum experimental safe gap (MESG) > 0.9 mm.
  • Bi-directionally working in pipes, whereby an operating pressure of 4.5 bar abs. and an operating temperature of 60 °C must not be exceeded.
  • All sizes are tested against “stabilized burning” and withstand this up to a max. burn time BT ≤ 1.0 min.
  • To detect a “stabilized burning” a temperature sensor must be installed at each endangered side.
  • Mounting is acceptable in any position, in horizontal as well as in vertical pipes.
