Stainless Steel Flare Part of Ignition Systems

The Stainless Steel Flare Part of Ignition Systems is a critical component designed to initiate and maintain stable ignition in industrial combustion and flare systems. Manufactured from oxidation-resistant stainless steels (321, UNS S32100; 310S, UNS S31000) or nickel-based alloys (Inconel 625, UNS N06625) via precision machining or investment casting, these parts—including ignition electrodes, spark plugs, and flame rods—are engineered to withstand high-temperature gas streams (up to 1,400°C/2,552°F) and repeated thermal cycling.

Designed for reliable spark generation and flame detection, the parts feature robust insulation and corrosion-resistant coatings, ensuring ignition success rates ≥99.5% even in wet, dusty, or chemically aggressive environments. They comply with ignition system standards like API 556 and NFPA 86, supporting both pilot and main burner ignition.

This casting is in the shape of long and crossed tube with inner through holes.

We use special calibration fixtures to adjust the castings to make it meet the linear and geometric tolerance.The inner deep holes are formed by soluble core and the inner casting surface which cannot be checked by visual are inspected by endoscope.

High-Temperature Performance: 321 stainless steel parts (with titanium stabilization) resist carbide precipitation at 800°C (1,472°F), while Inconel 625 electrodes maintain conductivity and mechanical strength at 1,200°C (2,192°F), ideal for high-enthalpy gas streams.

Corrosion & Erosion Resistance: Platinum or iridium plating on electrode tips enhances resistance to oxidation and metal migration, extending spark plug life by 50% in sulfuric acid vapor or salt-laden atmospheres.

Ignition Reliability Technology: Proprietary electrode gap design (0.8-1.2mm) and insulation materials (alumina ceramic) minimize arc quenching, ensuring consistent ignition across wide turndown ratios (10:1) and gas velocities (5-50 m/s).

Easy Integration: Standardized thread sizes (14mm, 18mm) and mounting flanges fit most commercial ignition systems, with optional explosion-proof enclosures for hazardous area applications (ATEX/IECEx certified).

The casting is part of flare ignition system.

The flare ignition systems are designed to safely burn off excess hydrocarbons released during industrial processes which need to be disposed of securely to avoid dangerous buildups or releases. Igniting these gases minimizes environmental hazards and maintains operational safety.

The flare parts castings are used in flare ignition systems,which play a crucial role in disposing of hydrocarbon waste, minimizing risks, and reducing environmental impact.They’re essential  in oil&gas industry,energy industry,petrochemical industry, etc.

Industrial Burners: Used in furnaces, kilns, and ovens for steel, glass, and cement production, where 310S flame rods detect pilot flames in 1,100°C (2,012°F) environments with high particulate loads.

Gas Turbines: Integral to dry low NOx (DLN) ignition systems, with Inconel 625 electrodes resisting thermal fatigue from rapid start-stop cycles in aerospace and power generation turbos.

Marine Engines: Installed in marine boiler igniters, offering saltwater corrosion resistance and reliable ignition in humid, high-vibration environments typical of cargo ships and offshore vessels.

Waste-to-Energy Plants: Initiates combustion in waste incinerators, with 321 stainless steel parts enduring chlorine and moisture-induced corrosion during municipal solid waste (MSW) processing.

Q: How does electrode material affect ignition performance?

A: Platinum-plated electrodes offer superior resistance to fouling and erosion in dirty fuels, while Inconel-based parts excel in extreme heat. Material choice depends on gas composition and temperature profile.

Q: Can these parts be used in hydrogen-rich ignition systems?

A: Yes—specialized designs with anti-hydrogen embrittlement treatments (e.g., low-carbon alloys and stress relief) ensure reliability in hydrogen (H₂) or hydrogen sulfide (H₂S) environments.

Q: What is the typical lifespan of a flame rod in continuous operation?

A: 1-3 years in clean gas services; 6-12 months in abrasive or corrosive environments. Regular cleaning (every 3 months) and insulation checks extend service life.
