U Type Outer Half Round Tube Shield
Half Round Tube Shield
Half Round Tube Shields by Ladhani Metal Corporation are precision-designed components used to protect boiler, superheater, and heat exchanger tubes from erosion, slag accumulation, scaling, and high-temperature oxidation. These shields are essential for industrial systems exposed to intense thermal cycling, high-velocity flue gases, and corrosive atmospheres. Their half-round form ensures quick and secure installation over curved or straight tube surfaces, significantly enhancing tube durability and reducing downtime.
1Cr20Ni14Si2 U Type Outer Half Round Tube Shield
The 1Cr20Ni14Si2 U Type Outer Half Round Tube Shield is made from a high-performance austenitic stainless steel alloy containing 20% chromium, 14% nickel, and approximately 2% silicon. This alloy provides excellent resistance to oxidation, high-temperature corrosion, and thermal fatigue, especially in oxidizing and carburizing environments. The outer U-type design is specifically intended to protect the outer arc of U-bend tubes in boilers, reformers, and heat exchangers, where flame, gas flow, and slag buildup cause the most wear.
• Outer U Type Half Round Tube Shield – Shields the outer curvature of U-bend tubes from flame impingement, gas erosion, slag attack, and thermal scaling.
Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of 1Cr20Ni14Si2 U Type Outer Half Round Tube Shields, offering custom-built shielding solutions for critical high-temperature and industrial systems.
Chemical Composition of 1Cr20Ni14Si2 – Austenitic Heat-Resistant Stainless Steel

Applications: Best suited for high-temperature, oxidizing environments in power generation, chemical processing, and furnace systems where excellent thermal and scaling resistance are required.
Uses
• Outer arc protection for U-bend tubes in superheaters and reheaters in thermal power plants
• Shields return bends in heat exchangers and steam reformers exposed to hot gases and flame
• Used in waste heat recovery boilers (WHRBs) and HRSGs to prevent surface oxidation and slag damage
• Suitable for petrochemical and chemical reactors operating under oxidizing or mildly carburizing conditions
• Applied in high-temperature industrial furnaces, incinerators, and reforming equipment
Features
• Excellent high-temperature resistance – Withstands service temperatures up to 1100°C with minimal deformation or scaling
• Oxidation and corrosion resistance – High Cr-Ni-Si composition forms a stable oxide layer for prolonged exposure protection
• Outer bend coverage – Provides critical protection for the most exposed and erosion-prone section of U-bend tubes
• Custom fabrication – Manufactured to match exact tube radius and diameter, ensuring a precise and stable fit
• Easy installation – Secured with clamps, tack welds, or stainless steel banding without disassembly
• Long-lasting performance – Enhances operational life and minimizes costly tube replacements in aggressive environments
Applications
• thermal and power generation – Protects outer U-bend tube surfaces from slag, soot, and flue gas corrosion
• petrochemical and refining – Shields return bends in reformers and heaters exposed to oxidizing and sulfur-rich gases
• waste heat recovery – Guards outer tube arcs in WHRBs and HRSGs against scaling and erosion
• metallurgy and cement processing – Used in high-temperature pipelines and ducts in furnaces and kilns
• process heating systems – Ideal for environments involving intense flame exposure and cyclic thermal loads
Conclusion
The 1Cr20Ni14Si2 U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a highly durable, heat-resistant shielding solution for protecting U-bend tube outer surfaces in extreme industrial environments. With superior resistance to oxidation, scaling, and thermal fatigue, it ensures long-term reliability and efficiency in power plants, reformers, and furnace systems.
