U Type Outer Half Round Tube Shield
Half Round Tube Shield
Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered components designed to safeguard boiler and heat exchanger tubes from erosion, scaling, and thermal degradation. These shields are essential for industrial systems subjected to high-temperature flue gases, particulate abrasion, and corrosive atmospheres. The half-round design allows for simple installation over both straight and curved tube surfaces, enhancing tube longevity and reducing unplanned maintenance.
SS 420 U Type Outer Half Round Tube Shield
The SS 420 U Type Outer Half Round Tube Shield is manufactured from SS 420, a high-carbon martensitic stainless steel offering excellent hardness, strength, and moderate corrosion resistance. This outer U-type shield is designed specifically to protect the outer arc of U-bend tubes, where direct exposure to flame, slag, and abrasive gas streams accelerates wear. SS 420’s heat resistance and hard surface make it well-suited for shielding critical tube areas in high-wear, high-temperature applications.
• Outer U Type Half Round Tube Shield – Provides robust coverage for the external curve of U-bend tubes, defending against mechanical erosion, scaling, and thermal fatigue.
Ladhani Metal Corporation is a prominent manufacturer, supplier, and exporter of SS 420 U Type Outer Half Round Tube Shields, delivering reliable protection in harsh industrial operating environments.
Chemical Composition of SS 420 – High-Carbon Martensitic Stainless Steel
• Carbon (C): 0.15 – 0.40%
• Manganese (Mn): ≤ 1.00%
• Phosphorus (P): ≤ 0.040%
• Sulfur (S): ≤ 0.030%
• Silicon (Si): ≤ 1.00%
• Chromium (Cr): 12.0 – 14.0%
• Iron (Fe): Balance
Applications: Best suited for high-temperature, abrasive environments where mechanical strength and surface durability are critical, with moderate corrosion exposure.
Uses
• Protection of U-bend outer surfaces in superheaters, reheaters, and economizers in thermal power plants
• Shielding external curves in gas heaters, exhaust systems, and flue ducts prone to slag or particulate erosion
• Applied in return bends of waste heat recovery systems and HRSGs to guard against high-velocity gas wear
• Ideal for industrial furnaces, incinerators, and heat exchangers operating in high-heat and abrasive zones
• Suitable for applications where resistance to scaling, mechanical stress, and oxidation is required
Features
• High hardness and wear resistance – Martensitic steel structure offers excellent protection against abrasion and mechanical impact
• Thermal durability – Performs well under high-temperature conditions with good resistance to scaling and thermal fatigue
• Outer arc shielding – Specifically designed to guard the most exposed curvature of U-bend tubes from direct flame and gas stream contact
• Precision-engineered – Fabricated to exact tube radius and diameter for secure, vibration-resistant installation
• Simple installation – Easily mounted using clamps, tack welds, or stainless banding without system disassembly
• Cost-efficient protection – Provides a durable solution with a balance of strength and corrosion resistance at an economical price
Applications
• thermal power stations – Used to shield outer curves of U-bend tubes from flame impingement and gas erosion
• industrial boilers and furnaces – Protects return bends in high-heat, high-wear zones prone to slag accumulation and scale formation
• waste heat recovery boilers – Installed in WHRB and HRSG systems to extend tube life under hot gas and particulate exposure
• chemical and petrochemical industries – Suitable for heaters and exchangers where thermal stress and gas impact degrade surfaces
• process heating systems – Applied in equipment handling high-velocity gas or steam that contributes to tube wear and surface damage
