Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered protective components designed to guard boiler and heat exchanger tubes from erosion, slag buildup, scaling, and high-temperature corrosion. These shields are widely used in power plants, petrochemical units, and thermal systems where tubes are exposed to hot gases, mechanical wear, and corrosive media. Their half-round structure ensures a secure fit over straight or curved tube sections, extending operational life and reducing tube failure. 1Cr18Ni9Ti U Type Outer Half Round Tube Shield The 1Cr18Ni9Ti U Type Outer Half Round Tube Shield is manufactured using a titanium-stabilized austenitic stainless steel known for its excellent corrosion resistance, high-temperature performance, and resistance to intergranular corrosion. This outer U-type shield is specifically designed to protect the external arc of U-bend tubes in boilers, heat exchangers, and superheaters where surface exposure to oxidizing gases and abrasive particles is common. Titanium stabilization improves weldability and structural integrity in high-temperature environments. • Outer U Type Half Round Tube Shield – Shields the outer curve of U-bend tubes from direct flame impingement, gas flow erosion, slag accumulation, and high-heat oxidation. Ladhani Metal Corporation is a reputable manufacturer, supplier, and exporter of 1Cr18Ni9Ti U Type Outer Half Round Tube Shields, offering durable and thermally stable solutions for critical industrial systems. Chemical Composition of 1Cr18Ni9Ti – Titanium-Stabilized Austenitic Stainless Steel • Carbon (C): ≤ 0.12% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 17.0 – 19.0% • Nickel (Ni): 8.0 – 11.0% • Titanium (Ti): ≥ 5 × C content • Iron (Fe): Balance Applications: Suitable for high-temperature, oxidizing, and corrosive environments where intergranular corrosion resistance and weldability are critical. Uses • Protection of outer U-bend surfaces in superheaters and reheaters of thermal and nuclear power plants • Shielding external arcs in waste heat recovery boilers (WHRBs) and HRSGs exposed to hot flue gases and ash particles • Applied in return bends of heat exchangers and reformers handling oxidizing and sulfur-bearing gases • Suitable for marine, petrochemical, and high-pressure steam systems requiring resistance to heat-induced corrosion • Used in welded applications where post-weld corrosion resistance and long-term structural stability are necessary Features • Excellent intergranular corrosion resistance – Titanium addition stabilizes carbon, preventing carbide precipitation during welding • High-temperature strength – Maintains structural integrity and oxidation resistance up to 850–900°C • Outer U-bend protection – Shields the most exposed and vulnerable arc from flame, thermal stress, and erosion • Precision engineering – Manufactured to exact tube radii and dimensions for a secure, movement-free installation • Easy to install – Can be mounted with clamps, stainless steel bands, or tack welds without dismantling the system • Long operational life – Reduces tube wear and thermal damage, improving overall system reliability Applications • power generation – Installed in superheater and reheater return bends exposed to thermal cycling and flue gas erosion • petrochemical plants – Protects U-bend tubes in reformers and exchangers from high-temperature and chemical degradation • waste heat recovery – Used in WHRBs and HRSGs to shield against slag buildup, scale formation, and high-velocity gas impact • marine and offshore systems – Suitable for condensers and heat exchangers exposed to salt-laden, oxidizing environments • industrial furnaces – Applied to radiant coils and return bends exposed to sustained heat and direct flame Conclusion The 1Cr18Ni9Ti U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a robust and thermally stable solution for protecting U-bend tube outer arcs in high-temperature and corrosive environments. With superior resistance to intergranular corrosion, oxidation, and thermal fatigue, this shield is ideal for boilers, heat exchangers, and petrochemical equipment requiring long-term protection and reliable performance.
