Half Round Shield for Boiler Tube
Ladhani Metal Corporation offers SS 316L Half Round Tube Shields designed to protect boiler tubes in thermal power plants, HRSGs, WHRBs, and industrial steam systems. Boiler tubes face severe service conditions such as high-temperature flue gas erosion, oxidation, and soot blower impact, which significantly reduce operational life. Manufactured from low-carbon molybdenum-bearing austenitic stainless steel grade SS 316L, these shields provide excellent corrosion resistance, superior scaling resistance, and improved weldability by minimizing the risk of carbide precipitation during welding.
Function of Boiler Tubes
• Carry water or steam through heating sections of the boiler
• Continuously exposed to high-temperature flue gases, ash, and corrosive particles
• Require Half Round Tube Shields in high-erosion, corrosive, and soot blower zones
Ladhani Metal Corporation manufactures, supplies, and exports SS 316L Half Round Tube Shields in various lengths, diameters, and thicknesses to cater to both domestic and international requirements.
