Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are designed to provide surface protection for boiler tubes, superheaters, and heat exchangers from erosion, slag deposition, and thermal wear. These shields are commonly used in low temperature superheaters (LTSH), economizers, and coil sections in power plants and industrial heating systems. Their half-round profile allows quick installation on exposed tube surfaces, ensuring prolonged tube service life and reduced maintenance frequency. SS 304 Half Round Tube Shield for LTSH Tube The SS 304 Half Round Tube Shield is manufactured from austenitic stainless steel grade 304, which offers excellent corrosion resistance, good mechanical strength, and thermal stability. Designed specifically for LTSH (Low Temperature Super Heater) applications, it protects the exposed surfaces of tubes from low-temperature corrosion, soot erosion, and gas flow damage. The shield is precisely fabricated to match the outer diameter of LTSH tubes, enabling a tight and reliable fit. 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 leading manufacturer, supplier, and exporter of SS 304 Half Round Tube Shields for LTSH applications, delivering durable and performance-oriented shielding solutions for thermal power and industrial process systems.
