Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered protective components designed to safeguard boiler and heat exchanger tubes from thermal fatigue, oxidation, and mechanical erosion. These shields improve system reliability and extend tube service life in harsh industrial environments. The half-round form enables simple installation and effective protection of exposed tube surfaces. SS 310 U Type Half Round Tube Shield The SS 310 U Type Half Round Tube Shield is a high-temperature protective sleeve designed to cover U-bend and straight sections of tubes in boilers, superheaters, and heat exchangers. Made from stainless steel grade 310, it offers outstanding resistance to oxidation, carburization, and thermal stress at elevated temperatures. The U-type design ensures complete protection of return bends, where tube degradation is most common. Available in both inner and outer U configurations, these shields are custom-bent to match tube radius and diameter. • Outer U Type Half Round Tube Shield – Protects the external arc of the U-bend from radiant heat, slag buildup, and erosion. • Inner U Type Half Round Tube Shield – Shields the internal curve of the bend from gas turbulence, scaling, and corrosion. Ladhani Metal Corporation is a leading manufacturer and exporter of SS 310 U Type Half Round Tube Shields, offering durable and tailored solutions for global heat transfer systems. Chemical Composition of SS 310 – High Temperature Austenitic Stainless Steel • Carbon (C): ≤ 0.25% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.045% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.50% • Chromium (Cr): 24.0 – 26.0% • Nickel (Ni): 19.0 – 22.0% • Iron (Fe): Balance Applications: Preferred in high-temperature operations where oxidation resistance, heat stability, and carburization resistance are essential. Uses • U-bend protection in superheater and reheater coils • Shielding curved tubes in furnace coils and process heat exchangers • Prevention of high-temperature erosion in WHRB and HRSG systems • Surface protection in reformers and chemical reactors • Safeguarding heat transfer tubes in incinerators and kilns Features • Made from high-quality SS 310, the shield offers superior resistance to oxidation, scaling, and high-temperature corrosion, making it suitable for continuous exposure up to 1100°C. • The inner and outer U-type configurations provide complete protection for both sides of curved tube bends, ensuring uniform shielding in the most erosion-prone areas. • Precision-formed to match the tube’s bend radius and diameter, ensuring a tight, vibration-free fit that enhances durability and minimizes tube wall exposure. • Retains mechanical strength and dimensional stability under cyclic thermal loading, preventing deformation, cracking, or failure in high-heat environments. • Offered in various finishes such as pickled, passivated, or bright annealed to suit different service conditions and enhance surface corrosion resistance. • Easily installed using welding, clamping, or banding methods without requiring tube removal, enabling quick field installation and minimal system downtime. • Fully customizable in terms of thickness, length, and radius, allowing seamless integration with existing boiler, furnace, or heat exchanger systems. Applications • thermal power plants – Protects U-bend coils in superheaters and reheaters. Resists scale formation and creep at high flue gas temperatures. • petrochemical refineries – Shields curved exchanger tubes in reformers and heaters. Maintains integrity under carburizing and oxidizing atmospheres. • waste heat recovery systems (WHRBs) – Guards return bends against ash and slag attack. Enhances tube durability in high-flow, abrasive environments. • chemical and fertilizer plants – Used in U-tube reactors and ammonia converters. Prevents corrosion and surface damage under cyclic thermal loads. • HRSGs and boilers – Applied to curved tube sections in heat recovery units. Ensures stability under rapid heating and cooling cycles. Conclusion The SS 310 U Type Half Round Tube Shield by Ladhani Metal Corporation offers superior protection for curved tube sections operating in high-temperature and corrosive service conditions. Its exceptional resistance to oxidation and carburization makes it ideal for thermal, chemical, and energy-intensive industries. Manufactured with precision, these shields are available in custom sizes and finishes, ensuring a tight fit and long-term durability.
