Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Ladhani Metal Corporation manufactures high-quality Half Round Tube Shields designed to protect boiler tubes from erosion, corrosion, and mechanical wear in heat transfer systems. These shields are precisely engineered to fit the curvature of boiler tubes, especially in areas exposed to flue gas turbulence and ash impact. The half-round design allows for easy installation and ensures consistent protection throughout the tube's operating life. Cr23Ni13 Half Round Tube Shield for LTSH Tube The Cr23Ni13 Half Round Tube Shield is fabricated using a high-temperature-resistant chromium-nickel alloy containing approximately 23% chromium and 13% nickel. This composition provides excellent resistance to oxidation, thermal shock, and high-temperature corrosion. It is particularly suited for shielding LTSH (Low Temperature Superheater) tubes that operate in areas where flue gases carry abrasive particles, resulting in gradual material degradation over time. The Low Temperature Superheater (LTSH) is a section in a boiler where saturated steam from the steam drum is superheated to a moderately higher temperature before entering the high-temperature superheater stages. Positioned in areas with relatively lower flue gas temperatures, the LTSH helps improve thermal efficiency and reduces moisture content in steam. Due to constant exposure to abrasive flue gases and ash, LTSH tubes are prone to wear and require protective shielding, such as half round tube shields, to extend service life. Ladhani Metal Corporation is a reliable manufacturer, supplier, and exporter of Cr23Ni13 Half Round Tube Shields, delivering robust and thermally stable components for boiler protection applications in demanding industrial conditions. Chemical Composition of Cr23Ni13 – High Chromium-Nickel Heat-Resistant Steel • Carbon (C): ≤ 0.10% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 22.0 – 24.0% • Nickel (Ni): 12.0 – 14.0% • Iron (Fe): Balance Applications: Ideal for high-temperature zones in boilers and furnaces where oxidation, scaling, and ash corrosion pose operational challenges.
