The flame arrester is designed to prevent flame transmission when flammable gas/air- or vapor/air-mixtures are present. The model FA in-line flame arrester is designed, manufactured and tested according to API 2000, EN 12874 and ISO 16852. Body material of arrester is available for nodular cast iron, cast steel, stainless steel grade 304, 316, 316L and special alloy steel for chemical resistance. The material of element is available for stainless steel grade 316L or special alloy steel for chemical resistance. The flame element is constructed with crimped ribbon metal.

Description of Protective System:
The in-line, bi-directional, deflagration flame arresters types FA-02; FA-03; FA-04; FA-05; FA-06; FA-08; FA-10; FA-12 are to prevent a flame transmission in case of deflagration of flammable gas – and/or vapour/air mixtures of the explosion group llA, at a maximum operating pressure po which is defined below and at maximum operational temperature of the flame arrester To = +60°C. Flame arresters are consists of flame arrester element tight between two flanges.
