Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are designed to protect boiler tubes, heat exchanger coils, and superheaters from erosion, scaling, slag accumulation, and corrosive flue gases. These shields are widely used in thermal systems such as power plants, chemical processing units, and waste heat recovery boilers to improve tube longevity and reduce maintenance frequency. Their semi-cylindrical form allows easy installation on straight or curved tube surfaces in high-wear zones. SS 316 Half Round Tube Shield for LTSH Tube The SS 316 Half Round Tube Shield is manufactured from molybdenum-bearing austenitic stainless steel grade 316. Known for its excellent resistance to pitting, crevice corrosion, and chemical attack, SS 316 is ideal for environments where flue gas contains chlorides, moisture, or mildly acidic compounds. Designed specifically for Low Temperature Superheater (LTSH) applications, this shield provides critical surface protection in zones where steam is moderately superheated and tubes are exposed to ash, soot, and 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 leading manufacturer, supplier, and exporter of SS 316 Half Round Tube Shields for LTSH applications, offering reliable and corrosion-resistant shielding solutions for extended tube performance.
