The HGS07 wire mesh flame arrester is a flame arrestor safety device installed on flammable gas pipelines or tank vent nozzles. It uses multi-layer stainless steel wire mesh as the flame arresting element, quenching flames through the fine pores of the mesh to effectively prevent external flame propagation to upstream pipelines or storage tanks. It features a simple structure, large flow area, and low pressure drop. Its core purpose is to be installed in vapor recovery systems, vent lines, small tank breather pipes, burner supply lines, etc., to rapidly block flame during accidental backfire, protecting equipment and personnel.

Product Drawing of HGS07 wire mesh flame arrester

1. Wire mesh flame arresting element: Made of multiple layers of pressed stainless steel wire mesh, providing uniform and fine pores for stable flame arresting performance with economical cost.

2. Large flow area, low pressure drop: High porosity of the mesh structure minimizes gas flow resistance without affecting normal system venting.

3. Simple structure, easy maintenance: No complex moving parts; the mesh can be removed for cleaning or replacement, resulting in low maintenance cost.

4. Multiple housing materials: Available in aluminum alloy, carbon steel, or stainless steel to suit various corrosive environments and pressure ratings.

5. Flexible connection options: Threaded or flanged connections are available for quick installation on small-bore pipelines (DN15～DN200).

6. Short-term high temperature resistance: Stainless steel mesh withstands instantaneous flame temperatures without burning or deforming easily.

7. Suitable for deflagration: Applicable for subsonic flame deflagration conditions; not suitable for stable detonation.

8. Compliant with relevant standards: Designed and manufactured according to GB/T 13347, ISO 16852, and other standards.
