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 316 U Type Outer Half Round Tube Shield The SS 316 U Type Outer Half Round Tube Shield is manufactured from SS 316, a molybdenum-bearing austenitic stainless steel known for its superior corrosion resistance, especially against chlorides, acidic media, and pitting. This outer U-type configuration is specifically designed to protect the outer curvature of U-bend tubes in boilers, superheaters, heat exchangers, and waste heat recovery systems. It offers effective shielding in high-temperature, corrosive environments where external tube surfaces are exposed to flue gases, slag accumulation, and erosion. • Outer U Type Half Round Tube Shield – Covers the external arc of U-bend tubes, guarding against flame impingement, thermal degradation, and corrosive gas attack. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of SS 316 U Type Outer Half Round Tube Shields, delivering precision solutions for demanding thermal and chemical processing applications. Chemical Composition of SS 316 – Austenitic Stainless Steel with Molybdenum • Carbon (C): ≤ 0.08% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.045% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 16.0 – 18.0% • Nickel (Ni): 10.0 – 14.0% • Molybdenum (Mo): 2.0 – 3.0% • Iron (Fe): Balance Applications: Ideal for high-temperature systems operating in corrosive environments with exposure to chlorides, acidic gases, steam, and thermal cycling. Uses • Outer arc protection of U-bend tubes in superheaters and reheaters in thermal and nuclear power plants • Shielding curved tube bends in petrochemical heat exchangers and steam reformers • Coverage for WHRB and HRSG outer U-bend sections exposed to abrasive and corrosive flue gas streams • Applied to return bends in condensers, evaporators, and marine heat exchangers exposed to saline or acidic media • Suitable for process industries requiring excellent corrosion resistance and thermal stability Features • Excellent corrosion resistance – Molybdenum-enhanced alloy provides high resistance to pitting, crevice corrosion, and chloride attack • Outer U-bend protection – Shields the most vulnerable outer curvature from erosion, heat stress, and slag impact • High-temperature durability – Maintains structural stability under continuous and cyclic heat conditions • Custom fitment – Manufactured to precisely match tube diameter and bend radius for a snug and vibration-free installation • Easy to install – Secured with clamps, tack welds, or stainless steel bands without system disassembly • Long service life – Reduces tube damage, extends maintenance intervals, and enhances operational efficiency Applications • power generation – Installed in U-bend tube outer arcs in superheaters and reheaters to prevent oxidation and surface scaling • petrochemical and refinery plants – Used in high-temperature heat exchangers and reformers exposed to corrosive process gases • waste heat recovery boilers – Shields outer tube bends from flue gas erosion and slag accumulation in WHRBs and HRSGs • chemical and fertilizer plants – Protects external surfaces of U-bends in reactors and ammonia reformers against acidic gas attack • marine and coastal installations – Ideal for heat exchangers and condensers operating in chloride-laden and saline environments Conclusion The SS 316 U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a robust and corrosion-resistant solution for protecting the outer arcs of U-bend tubes in heat exchangers, boilers, and thermal processing equipment. With superior resistance to chlorides, acids, and oxidizing gases, along with high-temperature performance and ease of installation, this shield is a dependable choice for power, petrochemical, and marine industry applications.
