Description

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. Cr23Ni13 U Type Half Round Tube Shield The Cr23Ni13 U Type Half Round Tube Shield is designed to provide high-temperature and corrosion protection for U-bend tube sections in critical thermal and process equipment. Made from Cr23Ni13, an austenitic stainless steel alloy containing approximately 23% chromium and 13% nickel, this shield offers excellent resistance to oxidation, scaling, and carburization. It is particularly effective in applications involving fluctuating temperatures, aggressive gas streams, and surface wear. The U-type design ensures complete protection of both the inner and outer arcs of curved tubes, where damage due to thermal and flow-induced stress is most likely to occur. • Outer U Type Half Round Tube Shield – Protects the outer bend radius from slag accumulation, flame impingement, and flue gas erosion. • Inner U Type Half Round Tube Shield – Shields the inner arc against turbulent flow wear, scale formation, and heat-induced deformation. Ladhani Metal Corporation supplies Cr23Ni13 U Type Half Round Tube Shields for use in high-performance industrial systems requiring reliable operation under thermal and chemical stress. Chemical Composition of Cr23Ni13 – Austenitic Heat-Resistant Stainless Steel • Carbon (C): ≤ 0.15% • Manganese (Mn): ≤ 1.50% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.50% • Chromium (Cr): 22.0 – 24.0% • Nickel (Ni): 12.0 – 14.0% • Iron (Fe): Balance Applications: Best suited for high-temperature applications requiring good resistance to oxidation, thermal fatigue, and moderate carburizing or corrosive environments. Uses • Protection of U-bend tubes in superheaters, reheaters, and boiler coils in thermal power plants • Shielding of tube bends in chemical reformers, preheaters, and gas-fired furnaces • Guarding return bends in WHRBs and HRSGs exposed to particulate-laden flue gases and cyclic heating • Coverage for high-temperature tube curves in petrochemical and refining units • Ideal for heavy industrial systems operating under oxidizing and moderately corrosive gas flow Features • Excellent heat resistance – Withstands continuous operation in high-temperature conditions while resisting scaling and oxidation. • Good corrosion resistance – Chromium and nickel content provide stability in oxidizing and mildly corrosive environments. • U-bend coverage – Available in inner and outer U-type designs for complete tube bend protection. • Precision fitment – Custom-engineered to match the tube's radius and diameter for a secure, stable installation. • Fast installation – Can be attached using clamps, tack welding, or stainless banding without interrupting system operation. • Long-lasting durability – Designed to endure thermal cycling and mechanical wear, reducing the need for frequent replacements. Applications • thermal and industrial boilers – Used in U-bends of superheaters and reheaters to prevent scaling, wear, and fatigue cracking. Enhances heat transfer and reliability. • petrochemical industries – Installed in high-temperature processing units such as reformers and gas converters to guard against carburizing gas streams. • waste heat recovery systems – Protects U-bend tubes in WHRBs and HRSGs from slag erosion and high-temperature oxidation. • chemical processing plants – Suitable for heat exchanger tube bends handling oxidizing gases and acidic vapors at elevated temperatures. • metallurgy and furnace systems – Shields return bends and elbows in air preheaters, combustion chambers, and radiant heating tubes. Conclusion The Cr23Ni13 U Type Half Round Tube Shield by Ladhani Metal Corporation offers durable and effective protection for U-bend tube sections in high-temperature and moderate corrosion service. With its balanced chromium-nickel composition, this shield ensures reliable resistance to oxidation, scaling, and erosion in demanding thermal environments.
