Industry Macro Environment: Flameless Explosion Venting Market Continues to Expand; Policy Creates Rigid Demand

① Standards-Driven Enforcement; Indoor Explosion Venting Demand Surges

GB 15605-2024 and GB 17919-2025 have been officially implemented, explicitly requiring that: for indoor process equipment and working conditions where explosion venting ducts cannot be routed outdoors, the use of explosion venting panels alone is prohibited — flameless explosion venting devices must be installed. The domestic flameless explosion venting market continues to grow steadily at an annual rate of approximately 9%–13%. Traditional grain, wood, and metal powder dust collection constitute the existing market, while new energy vehicles, lithium battery materials, fine chemicals, energy storage cabins, and pharmaceutical cleanrooms have become the fastest-growing incremental markets.

Existing Mainstream Products Have Clear Performance Shortcomings, Creating a Window for Technological Upgrade

② Currently, the market almost exclusively employs stainless steel crimped-flame-arrester-core flameless explosion venting devices:

• Advantages: Mature certifications, easy to clean, controllable cost.

• Pain Points: Virtually no shockwave attenuation capability. Explosion shockwaves directly impact factory walls, equipment supports, and surrounding precision equipment. The thermal radiation at the venting outlet is intense, posing high risk to personnel in close-proximity working conditions.

Numerous high-end customers (lithium battery, fine chemicals, enclosed facilities) have begun to raise higher requirements: not only "no open flame," but also reduction of shock loading, mitigation of secondary vibration and thermal radiation — this is precisely the unique selling point of metal foam composite structures.

③ Competitive Landscape Characteristics

Domestic manufacturers primarily compete on price with homogeneous standard crimped-core products. Imported brands (REMBE, Fike, etc.) dominate high-end projects but similarly lack enhanced shockwave attenuation solutions. A composite structure capable of dual suppression — flame quenching plus shockwave attenuation — can form a differentiated barrier, avoiding low-price commoditization.

Core Market Opportunities for the Composite Structure (Advantageous Tracks)

High Priority — Highest Commercialization Potential (High Match)

① Lithium Battery Industry Chain (Cathode Materials, Graphite Blending, Solvent Reactors, Energy Storage Cabins)

Facilities are densely packed with compactly arranged indoor enclosed equipment. Explosion shockwaves can easily trigger cascading thermal runaway in battery cells. Customers are willing to pay a premium for higher safety redundancy. This is a high-end explosion protection market with attractive gross margins.

② Fine Chemicals, Pharmaceuticals, and Solvent Vapor Reactors (Gas Explosion Working Conditions)

Low dust loading minimizes foam clogging risk. Cleanrooms and personnel operating areas impose strict controls on shockwaves and high-temperature flue gas.

③ Urban Indoor Facilities, Underground Spaces, and Compact Production Line Retrofit Projects

Old factory retrofits with limited space around venting outlets cannot tolerate strong shockwave propagation outward. Traditional flameless explosion venting device housings require structural reinforcement, whereas the composite approach enables equipment lightweighting.

④ Export Market (Southeast Asia, European ATEX Projects)

The overseas EN16009 standard system accepts composite flame-arrester structures. European and American customers have higher requirements for explosion loading and secondary disaster control, making high-performance solutions more competitive as a domestic-substitute offering.

Overall Prospect Summary

Against the backdrop of continually tightening domestic explosion protection regulations and sustained growth in rigid demand for indoor flameless explosion venting, the crimped flame arrester core + metal foam composite flameless explosion venting solution precisely addresses the industry pain point of insufficient shockwave attenuation in traditional products. It holds a clear differentiated competitive advantage in high-end enclosed working conditions such as new energy and fine chemicals, with favorable prospects in segmented markets. However, real-world constraints exist — including certification investment, customer awareness, and dust maintenance — making it suitable for a phased commercialization approach of "pilot projects first, then standardization, prioritizing high-end tracks." It is not suitable for near-term blanket rollout across general dust working condition markets.
