Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are protective components designed to guard heat exchanger coils, boiler tubes, and superheater assemblies from erosion, high-temperature scaling, slag accumulation, and corrosion. These shields are vital in high-performance industrial systems, including power plants, refineries, and chemical process units. Their half-round shape allows easy installation on both straight and curved tubes, improving system longevity while minimizing downtime and maintenance frequency. 1Cr20Ni14Si2 U Type Inner Half Round Tube Shield The 1Cr20Ni14Si2 U Type Inner Half Round Tube Shield is manufactured using a high-temperature austenitic stainless steel alloy with enhanced chromium, nickel, and silicon content. This alloy delivers excellent oxidation resistance, thermal fatigue resistance, and structural stability at elevated temperatures. The inner U-type configuration is tailored to cover the inner arc of U-bend tubes, offering critical protection where high-velocity gas, turbulence, and slag deposits can rapidly wear or degrade tube surfaces. • Inner U Type Half Round Tube Shield – Designed to protect the inner curvature of U-bend tubes from scaling, erosion, and heat-related damage in thermal systems. Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of 1Cr20Ni14Si2 U Type Inner Half Round Tube Shields, delivering high-performance shielding solutions for demanding high-temperature environments. Chemical Composition of 1Cr20Ni14Si2 – High Chromium-Nickel-Silicon Heat-Resistant Alloy • Carbon (C): ≤ 0.20% • Manganese (Mn): ≤ 1.50% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): 1.80 – 2.50% • Chromium (Cr): 19.0 – 21.0% • Nickel (Ni): 13.0 – 15.0% • Iron (Fe): Balance Applications: Ideal for continuous high-temperature operations involving oxidizing or sulfur-containing gases.
