Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered components used to protect boiler and heat exchanger tubes from erosion, scaling, and high-temperature corrosion. These shields are widely applied in industrial systems exposed to thermal cycling, aggressive gases, and particulate flow. Their half-round shape allows for simple and secure installation over straight or curved tube surfaces, extending tube life and reducing maintenance needs. SS 410 U Type Outer Half Round Tube Shield The SS 410 U Type Outer Half Round Tube Shield is made from SS 410, a hardenable martensitic stainless steel known for its excellent strength, toughness, and moderate corrosion resistance. This outer U-type configuration is designed to protect the external arc of U-bend tubes in heat exchangers, boilers, and reheaters where abrasive flue gases and mechanical wear are common. SS 410’s hardness and resistance to thermal fatigue make it suitable for shielding outer tube surfaces exposed to harsh industrial environments. • Outer U Type Half Round Tube Shield – Protects the outer curvature of U-bend tubes from erosion, scaling, and mechanical impact caused by high-velocity gas and slag deposits. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SS 410 U Type Outer Half Round Tube Shields, offering durable solutions for power generation and high-temperature applications. 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 Applications: Suitable for high-temperature environments with abrasive gas flow and mechanical stress, where moderate corrosion resistance is sufficient. Uses • Outer arc protection for U-bend tubes in boilers, superheaters, and reheaters in thermal power plants • Shields tube bends in economizers and waste heat recovery systems from flue gas erosion • Applied in return bends in gas processing heaters and exhaust systems subjected to particulate flow • Ideal for high-strength, mechanically demanding environments where wear resistance is critical • Used in utility boilers, process furnaces, and other industrial systems operating under moderate corrosion and high heat conditions Features • High mechanical strength – Martensitic structure provides excellent hardness and wear resistance for abrasive service conditions • Moderate corrosion resistance – Chromium content offers basic protection against oxidation and steam exposure • Outer bend coverage – Shields the most exposed and impact-prone arc of the U-bend tube • Precision fit – Custom-fabricated to match tube diameters and bend radii, ensuring tight, vibration-free installation • Easy to install – Mountable using stainless steel bands, clamps, or tack welds without dismantling the system • Cost-effective – Offers durable tube protection with high strength at a lower material cost compared to austenitic grades Applications • power generation – Protects outer curves of U-bend tubes in high-temperature zones of boilers and reheaters • petrochemical processing – Shields tube bends in process heaters and reformers from thermal and gas erosion • waste heat recovery – Applied in WHRBs and HRSGs to guard against slag impact and scale formation • industrial furnaces – Suitable for high-wear zones where heat and particulate flow cause surface degradation • general industry – Used in utility boilers and gas exhaust systems where mechanical protection is needed with moderate corrosion resistance Conclusion The SS 410 U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a reliable and economical solution for protecting U-bend tube outer surfaces in boilers, heat exchangers, and thermal process systems. With excellent mechanical strength, good thermal stability, and moderate corrosion resistance, it is ideal for industrial applications that demand abrasion resistance and long service life in high-temperature environments.
