Model L76C-UF

In-Line Flame Arrestor L76C-UF

The L76C-UF model is designed to inhibit flame propagation in gas piping systems and to protect low pressure tanks containing flammable liquids. Arrestors protect low flash point liquids from external sources of ignition providing increased fire protection and safety.

  • Flame arrestor element geometry maximizes flame quenching capability while minimizing pressure drop
  • Removable element housing for ease of maintenance
  • Spiral-wound, crimped ribbon flame element
  • Flame elements made standard with premium 316SS material, reducing corrosion
  • Bi-directional with respect to flow and ignition source

 

  • Connection Sizes: 2” through 12” 150# ASME Flanged Connection
  • Housing standard material: Carbon Steel, Stainless Steel
  • Bases standard material: Aluminum (2”-6” only), Carbon Steel, Stainless Steel
  • Flame element standard material: 316 Stainless Steel
  • Operational Temperature Range: -4 to 140 ºF (-20 to 60 ºC)
  • Gas Group: IEC IIA, NEC D
  • Maximum Operational Pressure: see charts and IOM
  • Burn Time: tBT 2.5 minutes or better at Atmospheric Pressure (see IOM)

Operational temperature range: -4 to 140º F (-20 to 60º C)

Bi-directional with respect to flow and ignition source

Specifications subject to change without notice. Certified dimensions available upon request.

Pneumatic tested to 15 psig as standard.

* MAWP does not reflect the maximum operational pressure of the flame arrestor. Please consult the specifications section of the product IOM for the correct maximum operational pressure of the arrestor.

MAWP, refers only to the maximum shell pressure allowed, it has no relation or influence on the flame arresting performance of the flame arrestor.

  • Exterior painting or coating available
  • Drains and instrumentation ports available
  • Factory installed thermocouples for flame sensing available
