KITO G 24 N – Bidirectional In-Line Detonation Flame Arrester

KITO® EFA-Det4-IIB3-…/…-1.2 is a bidirectional in-line detonation flame arrester for pipelines conveying flammable gases or vapors of flammable liquids. It is used to protect vessels, tanks, and process equipment from stable detonation propagating through piping. Tested and certified as detonation flame arrester type 4.

Operating Limits

  • Explosion groups: IIA1 to IIB3
  • MESG: ≥ 0.65 mm
  • Max operating pressure: 1.2 bar abs.
  • Max operating temperature: 60 °C
  • Installation: horizontal or vertical pipeline
  • Protection: bidirectional, for ignition from either side of the line.

Thermal Monitoring

Variants -T and -TT are equipped with one or two PT100 temperature sensors. With a single sensor, installation should be on the side where fire risk is anticipated. With two PT100s, both sides are monitored for short-duration burning.

Dimensions and Connections

Range covers NG 65 to NG 800, with connections from DN 25 to DN 400. Small sizes: PN 40; medium: PN 16; large: PN 10. Standard flange: EN 1092-1 type B1; optional ASME B16.5 Class 150 RF.

Materials

  • Body: cast steel 1.0619 or cast stainless 1.4408
  • Gasket: HD 3822 or PTFE
  • KITO element: fully replaceable
  • Shell: galvanized steel up to NG 400 or stainless 1.4571 / 1.4581
  • Mesh: stainless 1.4310 or 1.4571
  • Bolts/nuts: galvanized steel or A2

Application Selection

G 24 N is selected where bidirectional detonation protection is required for media up to IIB3, pressure up to 1.2 bar abs. DN selection should consider MESG, flow rate, pressure drop, gas density, temperature, sealing materials, and PT100 requirement. Flow curves are provided for air ρ = 1.29 kg/m³ at 273 K.

Description

KITO® EFA-Det4-IIB3-…/…-1.2

KITO® EFA-Det4-IIB3-…/…-1.2-T (-TT)

  • 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 IIB3 with a maximum exper-imental safe gap (MESG) ≥ 0.65 mm. Bi-directionally working in pipes, whereby an operating pressure of 1.2 bar abs. and an operating temperature of 60 °C must not be exceeded.
  • The installation of the detonation flame arrester into horizontal and vertical pipes is permissible.
  • Provided with one or two temperature sensors (PT 100) the armature is certified against short time burning from one or both sides.
  • If only one thermal sensor is attached, it must be installed into that part of the body from which a fire is expected.
