U Type Outer Half Round Tube Shield
Half Round Tube Shield
Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered protective components designed to guard boiler and heat exchanger tubes from erosion, slag buildup, scaling, and high-temperature corrosion. These shields are widely used in power plants, petrochemical units, and thermal systems where tubes are exposed to hot gases, mechanical wear, and corrosive media. Their half-round structure ensures a secure fit over straight or curved tube sections, extending operational life and reducing tube failure.
1Cr18Ni9Ti U Type Outer Half Round Tube Shield
The 1Cr18Ni9Ti U Type Outer Half Round Tube Shield is manufactured using a titanium-stabilized austenitic stainless steel known for its excellent corrosion resistance, high-temperature performance, and resistance to intergranular corrosion. This outer U-type shield is specifically designed to protect the external arc of U-bend tubes in boilers, heat exchangers, and superheaters where surface exposure to oxidizing gases and abrasive particles is common. Titanium stabilization improves weldability and structural integrity in high-temperature environments.
• Outer U Type Half Round Tube Shield – Shields the outer curve of U-bend tubes from direct flame impingement, gas flow erosion, slag accumulation, and high-heat oxidation.
Ladhani Metal Corporation is a reputable manufacturer, supplier, and exporter of 1Cr18Ni9Ti U Type Outer Half Round Tube Shields, offering durable and thermally stable solutions for critical industrial systems.

Applications: Suitable for high-temperature, oxidizing, and corrosive environments where intergranular corrosion resistance and weldability are critical.
Uses
• Protection of outer U-bend surfaces in superheaters and reheaters of thermal and nuclear power plants
• Shielding external arcs in waste heat recovery boilers (WHRBs) and HRSGs exposed to hot flue gases and ash particles
• Applied in return bends of heat exchangers and reformers handling oxidizing and sulfur-bearing gases
• Suitable for marine, petrochemical, and high-pressure steam systems requiring resistance to heat-induced corrosion
• Used in welded applications where post-weld corrosion resistance and long-term structural stability are necessary
Features
• Excellent intergranular corrosion resistance – Titanium addition stabilizes carbon, preventing carbide precipitation during welding
• High-temperature strength – Maintains structural integrity and oxidation resistance up to 850–900°C
• Outer U-bend protection – Shields the most exposed and vulnerable arc from flame, thermal stress, and erosion
• Precision engineering – Manufactured to exact tube radii and dimensions for a secure, movement-free installation
• Easy to install – Can be mounted with clamps, stainless steel bands, or tack welds without dismantling the system
• Long operational life – Reduces tube wear and thermal damage, improving overall system reliability
Applications
• power generation – Installed in superheater and reheater return bends exposed to thermal cycling and flue gas erosion
• petrochemical plants – Protects U-bend tubes in reformers and exchangers from high-temperature and chemical degradation
• waste heat recovery – Used in WHRBs and HRSGs to shield against slag buildup, scale formation, and high-velocity gas impact
• marine and offshore systems – Suitable for condensers and heat exchangers exposed to salt-laden, oxidizing environments
• industrial furnaces – Applied to radiant coils and return bends exposed to sustained heat and direct flame
Conclusion
The 1Cr18Ni9Ti U Type Outer Half Round Tube Shield by Ladhani Metal Corporation—manufacturer, supplier, and exporter—is a robust and thermally stable solution for protecting U-bend tube outer arcs in high-temperature and corrosive environments. With superior resistance to intergranular corrosion, oxidation, and thermal fatigue, this shield is ideal for boilers, heat exchangers, and petrochemical equipment requiring long-term protection and reliable performance.
