Applications • Thermal and Biomass Power Stations – Used to protect boiler tubes from ash erosion and gas turbulence in high-velocity flue paths. • Cement and Steel Industries – Shields kiln and heat recovery tubes from particulate impact, slag, and high-temperature dust environments. • Waste-to-Energy Plants – Guards tubes in combustion chambers and economizers where gas stream erosion and soot buildup are persistent issues. • Oil Refineries – Applied in heat exchangers and preheater tubes exposed to abrasive flow or moderate corrosion risk. • Pulp and Paper Mills – Used in black liquor recovery boilers and steam generators handling fibrous or corrosive waste products. • Air Preheaters – Ideal for tubes located in dust-laden environments requiring protection against wear and gas abrasion. Conclusion The SS 420 Half Round Tube Shield from Ladhani Metal Corporation offers a high-performance, wear-resistant solution for tube protection in mechanically aggressive and thermally intensive environments. Its martensitic structure provides outstanding surface hardness, making it especially effective in soot blower zones, high-velocity ducts, and areas subject to abrasive particle flow. While not intended for severe chemical environments, SS 420 delivers exceptional value where mechanical durability is the top priority.
