1. Specifically for deflagration flame arresting: Optimized design for subsonic flame (deflagration, flame speed typically ≤0.6 Mach) with high flame arresting efficiency, suitable for long pipelines or confined spaces where flame propagation may occur.
2. Corrugated plate flame arrestor element: Alternately wound multi-layer stainless steel corrugated and flat strips form uniform triangular/rectangular narrow passages, providing very short flame quenching distance and stable reliable performance.
3. Bidirectional flame arresting: Capable of blocking flame propagation from either direction, suitable for piping systems where combustion may initiate from either side.
4. Large flow area, low pressure drop: High porosity (≥90%) of the flame arrestor element minimizes gas flow resistance without affecting normal pipeline flow capacity.
5. Corrosion and temperature resistance: Element and housing made of 304/316L stainless steel, resistant to short-term high-temperature flame impact and corrosive media environments.
6. Compact structure, easy installation: Standard flange interfaces match pipeline; can be installed horizontally or vertically; removable housing allows easy extraction of the element for cleaning.
7. Code compliant: Designed and manufactured according to GB/T 13347, ISO 16852, EN 12874 and other standards, certified by authorized testing agencies.
8. Easy maintenance: Flame arrestor element can be periodically extracted for cleaning of carbon deposits or impurities and then reinstalled, eliminating the need for complete replacement.
