Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are high-precision protective elements designed to safeguard boiler and heat exchanger tubes against mechanical wear, erosion, and high-temperature gas attack. These shields are essential in industrial systems where exposure to thermal cycling, high-velocity gases, and abrasive particles can rapidly degrade unprotected tubing. SS 410 Half Round Tube Shield The SS 410 Half Round Tube Shield is a semi-cylindrical tube protector manufactured using stainless steel grade 410. As a martensitic stainless steel, SS 410 offers a unique combination of good corrosion resistance, high mechanical strength, and excellent wear resistance. It is particularly suitable for environments with moderate corrosion exposure and significant mechanical stress. The half-round shape is precisely formed to ensure a tight fit over exposed tubes, providing a durable and reliable barrier that extends tube service life in industrial boilers, heat exchangers, and process equipment. Chemical Composition of SS 410 – Martensitic Stainless Steel • Carbon (C): 0.08 – 0.15% • Manganese (Mn): ≤ 1.00% • Phosphorus (P): ≤ 0.040% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 11.5 – 13.5% • Nickel (Ni): ≤ 0.75% • Iron (Fe): Balance Uses • Boiler Tube Protection – Provides abrasion and erosion resistance in utility and industrial boilers where tubes face harsh combustion environments. • Heat Exchanger Shielding – Reduces mechanical wear caused by high flow velocities and particulate impact in condensers and evaporators. • Furnace Tube Safeguarding – Protects radiant and convection tubes from scale buildup and flame impingement in high-temperature furnace applications. • Steam and Process Line Protection – Extends the life of piping systems in moderately corrosive environments with mechanical stress. • Air Preheater and Economizer Units – Shields tubes from dust-laden gas erosion in flue gas recovery systems. Features • Excellent Wear Resistance – High hardness and toughness of SS 410 make it ideal for shielding tubes exposed to abrasive flows or soot-blowing operations. • Good Oxidation Resistance – Performs reliably in mildly corrosive and oxidizing environments up to 650°C (1200°F). • High Strength – Provides superior mechanical durability under vibration, pressure, and impact loading conditions. • Easy to Fabricate and Install – Half-round design allows for quick field installation and secure clamping or welding without altering system layout. • Economical Option – Offers a cost-effective tube protection solution where severe corrosion resistance is not critical. • Customization – Available in different thicknesses, diameters, lengths, and surface finishes (pickled or bright annealed). Applications • Thermal Power Plants – Used in boiler and superheater tubes to resist wear from flue gas erosion and thermal fluctuations. • Cement and Steel Industries – Protects tubes in high-wear areas exposed to dust, ash, and scale in kilns, coolers, and furnaces. • Oil Refineries – Applied in areas where high strength is required along with moderate corrosion resistance, such as preheaters or tube bundles. • Chemical Plants – Suitable for process tubes in mildly corrosive environments with strong flow dynamics or steam load cycling. • Pulp and Paper Industry – Shields tubes in recovery and power boilers exposed to high-pressure steam and abrasive residues. • Biomass and Waste-to-Energy Plants – Guards against erosion from fly ash and combustion residues in environmentally demanding systems. Conclusion The SS 410 Half Round Tube Shield from Ladhani Metal Corporation is a robust and reliable solution for protecting critical tube systems subjected to mechanical wear and thermal stress. Its excellent hardness and strength make it especially effective in applications involving high-velocity gas flow, abrasive particles, and fluctuating temperatures. While not suited for highly corrosive environments, SS 410 excels in systems where durability, cost-efficiency, and resistance to erosion are key priorities. With customizable sizing and expert engineering support, Ladhani Metal Corporation ensures dependable, application-specific shielding solutions for a wide range of industries.
