Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Half Round Tube Shields from Ladhani Metal Corporation are durable, precisely fabricated components used to protect boiler tubes from erosion, scaling, and corrosion caused by flue gas flow and particulate impact. Their half-round, semi-cylindrical structure is designed to conform closely to tube surfaces, especially in areas subjected to repeated thermal cycling or mechanical wear. These shields are extensively applied in boilers, heat exchangers, and waste heat recovery systems. 1Cr25Ni20Si2 Half Round Tube Shield for LTSH Tube The 1Cr25Ni20Si2 Half Round Tube Shield is manufactured from a high-performance chromium-nickel-silicon alloy designed for elevated-temperature service. With approximately 25% chromium, 20% nickel, and added silicon content, this alloy exhibits superior resistance to oxidation, thermal fatigue, and carburization. Its mechanical stability under high-temperature operation makes it a preferred material for protective applications in Low Temperature Superheater (LTSH) zones. 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 1Cr25Ni20Si2 Half Round Tube Shields, offering high-performance shielding solutions tailored for harsh, heat-intensive industrial environments.
