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. 1Cr13 U Type Half Round Tube Shield The 1Cr13 U Type Half Round Tube Shield is fabricated from 1Cr13, a martensitic stainless steel known for its excellent hardness, wear resistance, and moderate corrosion resistance. This U-type shield is ideal for protecting U-bend tube sections in systems where mechanical wear, steam erosion, and intermittent high temperatures are a concern. The U-shaped design offers precise coverage of both the inner and outer arcs of tube bends, especially in boiler coils, superheaters, and heat exchangers where localized wear and thermal impact are concentrated. • Outer U Type Half Round Tube Shield – Shields the outer curvature of the U-bend from gas flow abrasion, impact from slag particles, and heat-induced surface degradation. • Inner U Type Half Round Tube Shield – Protects the inner radius against turbulence-induced erosion, scaling, and mechanical fatigue. Ladhani Metal Corporation supplies 1Cr13 U Type Half Round Tube Shields for industrial applications where strength, hardness, and moderate corrosion protection are required at an economical cost. Chemical Composition of 1Cr13 – Martensitic Stainless Steel • Carbon (C): 0.15 – 0.20% • Manganese (Mn): ≤ 1.00% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 12.0 – 14.0% • Nickel (Ni): ≤ 0.60% • Iron (Fe): Balance Applications: Well-suited for mildly corrosive and abrasive environments involving steam, flue gases, or mechanical impact at moderate to high temperatures. Uses • Protection of U-bend tubes in superheaters, reheaters, and boiler coils • Shielding curved tubes in industrial furnaces, economizers, and condensers • Coverage for return bends in WHRBs and HRSGs subject to mechanical and thermal wear • Application in process gas heaters and utility boilers in petrochemical and power sectors • Ideal for systems where hardness and erosion resistance are more critical than high corrosion resistance Features • Good oxidation and scaling resistance – Chromium content offers adequate protection in dry, high-temperature environments. • High mechanical strength – Martensitic structure provides superior wear resistance and hardness, reducing erosion damage in turbulent flow areas. • Dual-bend protection – Available in both inner and outer U-type configurations for complete shielding of tube bends. • Custom fitment – Precisely manufactured to match specific tube radii and diameters, ensuring stable and secure installation. • Fast installation – Easily attached using clamps, banding, or tack welding without requiring system disassembly. • Economical solution – Provides effective protection in harsh environments with a cost-efficient stainless steel alloy. Applications • thermal power plants – Used on U-bend tubes in superheaters and reheaters where flue gas erosion and steam wear are present. Enhances system life and performance. • waste heat recovery boilers – Shields tube bends in WHRBs from slag, scale, and high-velocity gas streams, improving long-term reliability. • petrochemical industries – Suitable for curved tubes in heaters, exchangers, and gas furnaces exposed to heat and particulate flow. • general industrial boilers – Applied to return bends in utility boilers and process heaters for erosion and oxidation control. • chemical and refining sectors – Ideal for non-aggressive environments requiring mechanical protection more than extreme corrosion resistance. Conclusion The 1Cr13 U Type Half Round Tube Shield by Ladhani Metal Corporation offers strong mechanical protection and moderate corrosion resistance for U-bend tube sections in boilers, heat exchangers, and industrial heating systems. Its martensitic stainless steel composition provides superior wear resistance, making it well-suited for environments with steam erosion, thermal stress, and mechanical impact. Designed for easy installation and long-term durability, this shield is a practical solution for a wide range of thermal and utility applications.
