Explosion-proof Pipeline Flame Arresters

Suitable for both in-line and critical pipeline applications, our flame arresters are available in two core types: Deflagration Flame Arresters (for flame speeds below sonic velocity) and Detonation Flame Arresters (for supersonic flame speeds), covering all explosion groups and industrial scenarios. Every unit is manufactured in strict accordance with global safety standards to ensure maximum protection and long-term durability.

1.Superior Flame Suppression Performance: Effectively stops both deflagration and detonation flame propagation, with short-time burning resistance (1-30 minutes) and 100% no flashback after flame extinguishment-meeting the strict requirements of GB5908-2024 and ISO16852 standards.

2.Compliant with Global Standards: Manufactured in accordance with international standards including GB5908-2024 (China), ISO16852 (International), EN ISO 16852, and ATEX Directive 2014/34/EU. Suitable for explosion groups IIA, IIB, and IIC, covering all common flammable media such as methane, propane, ethylene, and hydrogen.

3.Durable & Corrosion-Resistant: Constructed with high-quality carbon steel or 316L stainless steel (customizable to duplex steel or Hastelloy for harsh environments). The flame element is made of corrosion-resistant stainless steel strips, ensuring long service life in high-temperature, high-pressure, and corrosive media scenarios.

4.Low Pressure Loss, High Flow Capacity: Optimized gap design balances flame suppression performance and fluid flow efficiency. Minimal pressure loss ensures no impact on normal pipeline operation, while high flow capacity adapts to various pipeline diameters and flow requirements.

5.Maintenance-Friendly Design: Modular structure allows easy disassembly, cleaning, and replacement of the flame element-no need to remove the entire unit from the pipeline. This design prevents element damage or misalignment during maintenance, especially suitable for environments prone to polymerization or crystallization contamination.

6.Versatile Installation & Compatibility: Available in flange (ANSI, DIN, GB, HG) and threaded (BSP/NPT) connection options, compatible with most industrial pipelines. Suitable for horizontal or vertical installation, with bidirectional protection capability for flexible application in different pipeline layouts.

6.Added Safety Features: Equipped with electrostatic cross-connection lines to prevent static buildup, reducing the risk of internal ignition. Optional temperature monitoring devices can be installed to activate secondary protection measures in case of flame stabilization on the element.
