Tube Erosion Half Sleeves
Universal Fab Technologies manufactures, supplies, and exports Half Round Tube Sleeves designed to protect boiler tubes, reheater tubes, superheater tubes, and economizer tubes from severe erosion, corrosion, and high-temperature wear. These sleeves cover the exposed half section of the tube that faces maximum impact from high-velocity flue gases, abrasive ash particles, and soot blower jets.
Function of Half Round Tube Sleeves
• Provide targeted erosion and corrosion resistance in critical tube areas
• Shield tubes from high-velocity flue gases, ash particle erosion, and oxidation
• Prevent thinning and localized wear of tube walls
