Ladhani Metal Corporation manufactures high-strength SS 420 Outer Half Round 90 Degree Bend Tube Shields engineered to protect the outer arc of 90-degree bends and U-bend tubes in boilers, superheaters, reheaters, and heat exchangers. Made from martensitic stainless steel grade SS 420, these shields provide excellent resistance to wear, scaling, and moderate corrosion. With high hardness and superior mechanical durability, SS 420 shields are ideal for protecting high-stress bend sections exposed to fly ash erosion, abrasive particulate flow, and elevated temperatures. The semi-cylindrical design is precisely formed to match the outer curvature of tube bends, delivering a close, secure fit that enhances thermal protection and structural integrity. These shields are widely used in industries requiring impact resistance and long-term durability in high-temperature service environments. Ladhani Metal Corporation is a reliable manufacturer, supplier, and exporter of SS 420 Outer Half Round 90 Degree Bend Tube Shields, offering custom-made options suited to specific plant and coil requirements. SS 420 Grade Chemical Composition – Martensitic Stainless Steel • Carbon (C): 0.15 – 0.40% • Manganese (Mn): ≤ 1.00% • Phosphorus (P): ≤ 0.040% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 12.0 – 14.0% • Nickel (Ni): ≤ 0.75% • Iron (Fe): Balance Applications: Suitable for use in high-temperature, erosion-prone boiler environments, waste heat recovery units, and thermal process systems requiring high hardness and strength. Uses • Protection of outer U-bends and 90-degree curves in boilers and HRSGs • Applied in waste heat sections of reformers and exhaust ducts • Shields curved tube surfaces from mechanical impact and fly ash erosion • Ideal for process units where scale and soot buildup are prevalent Features • High hardness – Provides excellent wear and erosion resistance • Thermal endurance – Performs reliably under elevated temperatures • Corrosion resistance – Withstands flue gas and mildly aggressive media • Precision-engineered – Conforms to tube geometry for optimal fit • Flexible mounting – Clamp-on, weld-on, or banding as per application • Custom sizes – Offered in multiple lengths, bend radii, and thicknesses Applications • Thermal power plants – Shields high-wear tube bends in superheater and reheater sections • Waste heat boilers – Protects curved sections in ash-rich environments • Cement and pulp industries – Resists scale and gas flow damage • Petrochemical plants – Used in high-temperature convection and process coils Conclusion The SS 420 Outer Half Round 90 Degree Bend Tube Shield by Ladhani Metal Corporation offers high-performance protection for curved tubes in demanding thermal and abrasive environments. With superior hardness, precise form, and corrosion resistance, it ensures longer service life and reduced maintenance in high-wear zones.
