Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are designed to protect heat exchanger tubes, boiler coils, and superheater assemblies from erosion, scaling, and surface degradation in high-temperature and corrosive environments. These shields are used extensively in power plants, chemical processing units, and industrial heating systems. Their half-round construction enables fast and secure installation over both straight and curved tube surfaces, providing an effective barrier against damage from flue gas, slag, and particulate impact. SS 430 U Type Inner Half Round Tube Shield The SS 430 U Type Inner Half Round Tube Shield is manufactured from ferritic stainless steel grade 430, known for its good corrosion resistance, excellent thermal conductivity, and oxidation resistance. It performs reliably in moderate-temperature applications and provides dependable protection against scaling and surface deterioration. The inner U-type configuration is specifically engineered to cover the inside arc of U-bend tubes, which are particularly vulnerable to high-velocity gas flow and localized heat concentration. • Inner U Type Half Round Tube Shield – Covers the internal curvature of U-bend tubes to guard against turbulence-driven erosion, slag buildup, and scaling in thermal systems. Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of SS 430 U Type Inner Half Round Tube Shields, offering reliable protection components for heat-exposed industrial systems. Chemical Composition of SS 430 – Ferritic Stainless Steel • Carbon (C): ≤ 0.12% • Manganese (Mn): ≤ 1.00% • Phosphorus (P): ≤ 0.040% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 16.0 – 18.0% • Nickel (Ni): ≤ 0.75% • Iron (Fe): Balance Applications: Suitable for moderately corrosive and oxidizing environments where high thermal conductivity and scaling resistance are required, especially in non-welded systems. Uses • Installed on inner arc of U-bend tubes in boiler and superheater coils subject to flue gas turbulence • Protects return bends in WHRBs and HRSGs from surface degradation and slag impact • Used in heat exchangers and process heaters with moderate corrosion and temperature exposure • Applied in thermal processing plants, food-grade heating systems, and chemical units • Effective for curved coil protection in dryers, economizers, and incinerator heat recovery sections Features • Good corrosion and oxidation resistance – Performs well in moderately aggressive environments • Inner arc coverage – Specifically shields areas affected by heat, scale, and turbulent flow • Cost-effective – Offers a balance between performance and affordability for general-purpose applications • Thermal stability – Maintains structural integrity at service temperatures up to 815°C • Custom-fabricated – Tailored to match specific tube bend radius and outer diameter for secure fit • Easy installation – Compatible with clamp-on, banding, or weld-on mounting for fast and efficient assembly Applications • power generation – Used in superheater and economizer return bends to prevent scale and erosion • chemical and food industry – Applied in heat recovery systems requiring corrosion-resistant inner arc protection • waste heat recovery – Installed in WHRB and HRSG curved tubes to reduce slag and flue gas impact • dryers and kilns – Shields inner U-bend tubes in rotating or stationary heating equipment • process heating units – Provides mechanical and thermal protection for tubes exposed to oxidizing gas streams Conclusion The SS 430 U Type Inner Half Round Tube Shield by Ladhani Metal Corporation – manufacturer, supplier, and exporter – is a reliable and economical solution for protecting the inner arcs of U-bend tubes in moderately corrosive and thermal environments. With its ferritic composition, good thermal performance, and ease of installation, it is ideal for general-purpose heat system applications.
