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 Half Round Tube Shield The SS 316L U Type Half Round Tube Shield is specifically designed to offer enhanced protection to U-bend sections in heat exchangers, superheaters, and steam reformers. Fabricated from SS 316L, a low-carbon austenitic stainless steel alloyed with molybdenum, it delivers superior resistance to pitting, crevice corrosion, and intergranular attack in chloride-rich and high-temperature environments. The U-type design allows for seamless coverage of both the inner and outer arcs of tube bends, where thermal and mechanical stresses are most concentrated. • Outer U Type Half Round Tube Shield – Protects the outer bend of the tube against high-velocity gas impact, slag accumulation, and surface oxidation. • Inner U Type Half Round Tube Shield – Shields the inner curve from localized erosion, turbulence-related wear, and thermal fatigue cracking. Ladhani Metal Corporation manufactures and supplies SS 316L U Type Half Round Tube Shields for industries operating in corrosive, welded, or high-heat service conditions where enhanced durability and metallurgical stability are critical. 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: Specifically suited for high-chloride, welded, and high-temperature systems where corrosion resistance and thermal stability are essential. Uses • Protection of U-bend tube sections in superheaters and reheaters in thermal power plants • Coverage for return bends in chemical heat exchangers and ammonia reformers • Shielding curved tube segments in WHRBs and HRSGs exposed to thermal cycling • Corrosion and wear protection in condensers and evaporators operating with chlorides or acidic gases • Ideal for coastal, offshore, and marine installations involving saline or humid environments Features • Corrosion-resistant low carbon grade – SS 316L’s reduced carbon content ensures resistance to sensitization and intergranular corrosion after welding. • High-performance under heat – Maintains structural integrity and corrosion resistance in elevated temperature applications. • Dual-bend protection – Available in inner and outer U-type configurations to safeguard the entire arc of the U-bend. • Custom-formed profiles – Engineered to precisely fit tube diameter and bend radius for secure and stable installation. • Quick installation – Designed for easy mounting via tack welds, banding, or clamping without requiring tube disassembly. • Tailored dimensions – Manufactured in a range of thicknesses, lengths, and profiles to meet exact project needs. Applications • thermal power plants – Installed on U-bend tubes in superheaters and reheaters to mitigate scale formation and corrosion due to flue gases. Enhances heat exchanger reliability and life span. • petrochemical refineries – Used in steam reformers and exchangers handling chlorides, acids, and hydrocarbons. Ensures long-term corrosion resistance in aggressive environments. • waste heat recovery units – Protects U-shaped tubes from erosion and cracking caused by fluctuating gas velocities and slag deposits. • fertilizer and chemical plants – Shields critical tube bends from acidic or chloride-containing media in reformers and process heaters. • marine and coastal systems – Provides anti-corrosion protection in salt-laden and humid atmospheres for extended tube life. Conclusion The SS 316L U Type Half Round Tube Shield by Ladhani Metal Corporation is a robust and corrosion-resistant solution for protecting U-bend tube sections in heat-intensive and chemically aggressive systems. With its low carbon content and molybdenum enhancement, it ensures excellent resistance to pitting, scaling, and intergranular corrosion. Available in inner and outer U-bend configurations and tailored to match system specifications, these shields offer reliable, long-lasting tube protection in power, chemical, marine, and industrial sectors.
