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 316L U Type Outer Half Round Tube Shield The SS 316L U Type Outer Half Round Tube Shield is manufactured from SS 316L, a low-carbon molybdenum-bearing austenitic stainless steel known for its superior corrosion resistance and excellent weldability. This outer U-type configuration is designed to protect the external arc of U-bend tubes in boilers, superheaters, heat exchangers, and waste heat recovery systems. The low carbon content of SS 316L reduces the risk of sensitization and intergranular corrosion, making it ideal for welded systems exposed to chlorides, acidic gases, and steam. • Outer U Type Half Round Tube Shield – Offers full coverage to the outer curvature of U-bend tubes, shielding against erosion, slag buildup, high-temperature oxidation, and chemical attack. Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of SS 316L U Type Outer Half Round Tube Shields, delivering precision-built, long-lasting solutions for demanding industrial applications. Chemical Composition of SS 316L – Low-Carbon Austenitic Stainless Steel • Carbon (C): ≤ 0.03% • 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: Suited for high-temperature and corrosive environments requiring superior resistance to chlorides, acids, and weld-induced corrosion. Uses • Protection of U-bend outer arcs in superheaters and reheaters in thermal and nuclear power stations • Shielding tube bends in chemical heat exchangers and steam reformers exposed to chlorides and acidic gases • Outer bend coverage for WHRB and HRSG tubes subjected to flue gas flow, scaling, and erosion • Applied to return bends in condensers and evaporators in marine and coastal facilities • Ideal for pharmaceutical, food processing, and clean energy systems requiring low carbon stainless steel Features • Exceptional corrosion resistance – Molybdenum addition enhances resistance to pitting, crevice corrosion, and chlorides • Low carbon content – Minimizes the risk of sensitization and intergranular corrosion after welding or high-heat exposure • High-temperature capability – Maintains performance under cyclic heating and thermal stress conditions • Precision fitment – Custom-fabricated to match tube diameter and radius, ensuring tight, vibration-free installation • Easy installation – Mountable with clamps, banding, or tack welds without requiring shutdown or disassembly • Long-term durability – Withstands corrosive gases, scaling, and erosion, extending tube life and reducing downtime Applications • thermal power plants – Protects outer arcs of U-bend tubes from flue gas erosion and scaling in high-temperature zones • chemical and petrochemical plants – Shields return bends in reformers and exchangers operating with corrosive process media • waste heat recovery systems – Provides protection in WHRBs and HRSGs from thermal fatigue and particulate-laden flue gases • marine and offshore facilities – Suitable for chloride-rich environments such as desalination plants and coastal condensers • process and pharmaceutical industries – Ensures corrosion-resistant performance in systems with stringent cleanliness and durability requirements Conclusion The SS 316L U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a corrosion-resistant, precision-engineered solution for protecting U-bend tube outer surfaces in boilers and heat exchangers. Its low carbon content, molybdenum-enhanced alloy composition, and excellent weldability make it ideal for harsh industrial environments requiring high performance and reliability. Designed for easy installation and long service life, it is a trusted choice for power, petrochemical, marine, and process applications.
