The In-Line Deflagration Flame Arrestor is a critical industrial safety device engineered to prevent the dangerous spread of flammable gases and combustible liquid vapors. Typically installed within pipelines conveying combustible gases or on ventilated storage tanks, this device acts as a reliable barrier against the propagation of flames, including both deflagration and detonation events. The core construction of the flame arrestor is meticulously designed, comprising a highly efficient fire-retardant core, a durable fire-retardant shell, and essential supporting accessories. By rapidly absorbing heat and extinguishing flames before they can travel further down the piping system, this equipment plays an indispensable role in safeguarding industrial facilities, protecting valuable assets, and ensuring the safety of on-site personnel during the handling of volatile substances.
Complementing the flame arrestor system, the fire breathing valve produced by our company features a highly optimized and simplified structure designed for superior operational efficiency. It ensures a substantial ventilation volume while maintaining minimal leakage, which is crucial for balancing tank pressure and reducing material loss. The valve exhibits excellent corrosion resistance and insulation properties, making it highly adaptable to harsh industrial environments. A key advantage is the utilization of premium polytetrafluoroethylene (PTFE) material in its construction. This specific material choice provides exceptional low-temperature resistant and highly effective anti-frost capabilities, ensuring reliable continuous operation even in freezing climates. Furthermore, the breathing valve is equipped with a dedicated electrostatic protection device. This crucial safety feature ensures that the valve and the storage tank maintain the exact same electrical potential at all times, thereby eliminating the risk of static electricity accumulation and potential spark generation in highly explosive atmospheres.
The performance of the In Line Flame Arrestor relies heavily on its internal fire element, which is housed securely within the protective shell. We primarily utilize two highly effective types of filter elements to meet diverse industrial requirements: the metal mesh filter element and the corrugated filter element.
The metal mesh filter element is constructed from high-quality stainless steel or copper mesh, carefully arranged in overlapping layers to create a tortuous path that effectively quenches approaching flames. To guarantee optimal flame-arresting performance, this filter is manufactured to precise specifications. It utilizes wire with a specific diameter ranging from 0.23-0.315 mm. For typical applications, these arrestors usually employ a 16-22 mesh configuration constructed with 4-12 layers. This multi-layered metal mesh design provides an excellent balance between flame quenching capability and acceptable fluid flow rates, making it a dependable choice for standard deflagration protection.
Alternatively, the corrugated filter element offers robust protection for more demanding operational scenarios. This element is structurally supported by high-strength materials, specifically stainless steel, copper-nickel alloy, aluminium, or aluminium alloy. The corrugated flame retardant design is specifically engineered to prevent the fierce and rapid flames associated with deflagration. It is built to withstand significant mechanical shocks and thermal effects generated during a combustion event. Beyond its exceptional structural integrity, the corrugated filter element features a remarkably low flow resistance, ensuring that normal pipeline operations and gas transfer processes are not significantly hindered. Additionally, its structural design makes it exceptionally easy to clean and replace during routine maintenance, significantly reducing operational downtime and long-term maintenance costs for industrial facilities.
