Outer Half Round 90 Degree Bend Tube Shields
Ladhani Metal Corporation offers 1Cr25Ni20Si2 Outer Half Round 90 Degree Bend Tube Shields specifically designed to protect the outer curvature of U-bends and 90-degree turns in high-temperature tubes used in boilers, superheaters, reheaters, heat exchangers, and industrial furnaces. Made from high-alloy austenitic stainless steel grade 1Cr25Ni20Si2, these shields provide excellent resistance to oxidation, high-temperature corrosion, and thermal fatigue. The added silicon content enhances the steel’s oxidation resistance and structural stability in severe thermal environments.
The semi-cylindrical design is precisely formed to contour the bend radius of return tubes, creating an effective barrier against particulate erosion, ash impact, and high-velocity gas flow. 1Cr25Ni20Si2 shields are ideal for thermal power generation and industrial systems exposed to oxidizing, carburizing, and dry corrosive atmospheres. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of 1Cr25Ni20Si2 Outer Half Round 90 Degree Bend Tube Shields, offering tailored configurations to meet diverse thermal protection requirements.
