Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are protective components engineered to shield boiler tubes, superheaters, and heat exchangers from erosion, scaling, and ash impact. These shields are widely used in thermal power plants, industrial steam systems, and waste heat recovery units to prolong tube life and enhance operational reliability. Their semi-cylindrical shape allows for easy installation over exposed tube surfaces, especially in zones exposed to abrasive flue gases and thermal stress. SS 310S Half Round Tube Shield for LTSH Tube The SS 310S Half Round Tube Shield is manufactured from low-carbon austenitic stainless steel grade 310S. With high chromium and nickel content, it offers excellent resistance to oxidation and scaling at elevated temperatures, while its reduced carbon level enhances weldability and reduces the risk of sensitization. This makes it ideal for Low Temperature Superheater (LTSH) applications, where tubes are exposed to flue gas streams, ash particles, and moderate thermal cycling. 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 trusted manufacturer, supplier, and exporter of SS 310S Half Round Tube Shields for LTSH tubes, offering high-performance shielding solutions for long-term service in boiler and heat recovery systems. Chemical Composition of SS 310S – Low Carbon Austenitic Stainless Steel • Carbon (C): ≤ 0.08% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.045% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.50% • Chromium (Cr): 24.0 – 26.0% • Nickel (Ni): 19.0 – 22.0% • Iron (Fe): Balance Applications: Suitable for areas with exposure to moderate temperatures, oxidizing gases, and ash deposition where high-temperature strength and corrosion resistance are critical.
