KFD Detonation Proof In-Line Flame Arrester
KFD Detonation Proof In-Line Flame Arrester Overview
ZIRCO is proud to distribute KSPC KFD Detonation Proof In-Line Flame Arresters as the official representative for Western Canada. These advanced safety devices are designed, manufactured and tested according to the most rigorous international standards including API 2000, BS 7244, EN 12874, ISO 16852, USCG, and IMO MSC/Circ.677, providing critical flame protection for complex piping systems in industrial facilities.
The KFD represents the highest level of flame arrester technology, specifically engineered to stop flame propagation in manifolded or long-run piping systems where flame velocities can reach dangerous levels. Unlike deflagration flame arresters that only handle subsonic flame speeds, the KFD is designed to halt ignited flammable vapors at both subsonic AND supersonic velocities (detonation conditions), providing comprehensive protection for the most demanding applications.
Built by Korea Steel Power Corp. (KSPC) to the highest standards, these detonation-proof flame arresters are rated for continuous burning against the 316L stainless steel flame cell and deliver dependable performance in critical applications throughout Western Canada's oil & gas, petrochemical, and processing sectors where maximum protection is essential.

Maintenance Requirements
Periodic inspection and maintenance is required to ensure continued optimal performance and safety compliance. The KFD detonation-proof in-line flame arrester is designed for maintenance access to minimize downtime in critical pipeline operations.
The cell assembly can be removed for inspection and cleaning purposes. Cleaning should be accomplished using appropriate methods that do not damage the precision flame cell openings. Any deformation of the cell openings may hamper flow through the cell and reduce effectiveness.
The gaskets should be inspected regularly and replaced if necessary to maintain proper sealing and prevent bypass of the flame arrester element. Given the critical nature of detonation protection applications, ZIRCO provides comprehensive maintenance support and replacement parts for Western Canada customers.
What Is a Detonation Proof In-Line Flame Arrester?
A detonation proof in-line flame arrester is an advanced safety device installed within pipelines to prevent the propagation of flame at both subsonic AND supersonic velocities. Unlike deflagration flame arresters that only handle slow-moving (subsonic) flames, detonation flame arresters are designed to stop high-velocity detonation waves that can develop in manifolded or long-run piping systems.
Understanding the Difference: When a flame travels through a pipe, it can accelerate due to turbulence and flame front instabilities. In short pipe runs, flames typically remain at subsonic velocities (deflagration). However, in manifolded systems or long piping runs, flames can accelerate to supersonic velocities, creating a detonation wave with significantly higher energy and destructive potential.
The KFD utilizes a robust 316L stainless steel flame cell engineered to withstand and quench both deflagration and detonation flames. When a flame attempts to pass through the element, the heat is absorbed through the metal surfaces, cooling the flame below its ignition temperature and extinguishing it even at supersonic velocities.
Additionally, the KFD is rated for continuous burning against the flame cell, meaning it can sustain prolonged flame exposure without failure - a critical capability for applications where flames may persist until emergency response teams can intervene. With certifications from USCG and IMO, the KFD is suitable for both land-based industrial facilities and marine applications worldwide. ZIRCO provides expert application support to help determine if your system requires detonation-level protection.

| Application | Simple pipe runs, vent pipes, end-line applications | Manifolded or long-run piping systems |
| Cost | Lower cost for standard applications | Higher cost for advanced protection |
| Certifications | API 2000, BS 7244, EN 12874, ISO 16852 | All above PLUS USCG, IMO |
| Continuous Burning | Not typically rated | Rated for continuous burning |
| When to Use | Standard applications with short pipe runs | Critical applications with complex piping |
