Half Round Shield
Ladhani Metal Corporation manufactures and exports SS Half Round Shields for LTSH (Low Temperature Superheater) Tubes, Type-IV, designed to protect boiler tubes against erosion, oxidation, and abrasive wear. LTSH tubes in Type-IV sections operate in the convection pass of boilers, where flue gas velocities and ash particles cause surface thinning and premature failure. These shields are precision-engineered to provide extended protection and ensure long service life of superheater tubes in power generation and industrial boilers.
Function of LTSH Tubes
• Carry steam through the low-temperature superheater section of the boiler
• Exposed to erosive flue gases, abrasive fly ash, and soot blower impacts
• Protected with Half Round Shields to reduce erosion, oxidation, and tube maintenance
