Half Round Tube Shield

Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are high-performance components designed to protect heat exchanger and boiler tubes from thermal damage, erosion, and high-temperature corrosion. These shields play a vital role in extending tube life and ensuring stable operation in demanding industrial environments such as petrochemical plants, power generation facilities, and high-temperature furnaces. 1Cr25Ni20Si2 Half Round Tube Shield The 1Cr25Ni20Si2 Half Round Tube Shield is a semi-cylindrical tube protector made from a heat-resistant alloy consisting of 25% chromium, 20% nickel, and 2% silicon. This alloy is known for its outstanding resistance to oxidation, carburization, and scaling at elevated temperatures, often exceeding 1100°C. The presence of silicon further enhances its oxidation resistance by forming a stable protective film on the surface. These shields are precision-formed in a half-round profile for easy clamping or welding over the tube surface, delivering a tight and durable fit. Chemical Composition of 1Cr25Ni20Si2 – Heat-Resistant ss Austenitic Alloy • Carbon (C): ≤ 0.20% • Silicon (Si): 1.50 – 2.50% • Manganese (Mn): ≤ 1.50% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Chromium (Cr): 24.0 – 26.0% • Nickel (Ni): 19.0 – 22.0% • Iron (Fe): Balance Uses • Superheater and Reheater Tube Protection – Shields tubes from oxidation and metal dusting under high steam and flue gas temperatures in utility boilers. • Furnace Tube Protection – Prevents damage from flame impingement, scaling, and spalling in radiant and convection furnace zones. • Reforming and Cracking Units – Used in petrochemical plants to protect process tubes from carburization and oxidation during prolonged high-temperature service. • Air Preheaters and Heat Recovery Systems – Guards tubes from thermal fatigue and corrosive ash erosion in waste heat systems. • Gas-Fired and Biomass Boilers – Applied to protect critical tube sections exposed to high-velocity combustion gases and corrosive deposits. Features • Superior Oxidation Resistance – The combination of chromium, nickel, and silicon provides long-term stability in oxidizing environments above 1000°C. • Excellent Carburization and Sulfidation Resistance – Performs well in carbon-rich and sulfur-laden atmospheres, making it ideal for petrochemical service. • High Mechanical Strength – Retains structural integrity under thermal cycling and mechanical load at elevated service temperatures. • Precision Half-Round Design – Ensures easy fitment over existing tubes with minimal disruption to equipment layout or flow design. • Enhanced Surface Protection – Silicon contributes to the formation of a dense oxide scale, minimizing material loss due to scaling. • Custom Dimensions – Available in a range of thicknesses, diameters, and lengths with optional surface treatments like bright annealing and passivation. Applications • Thermal Power Plants – Used in critical boiler zones such as superheaters and economizers where high-temperature oxidation resistance is required. • Petrochemical and Refining Industries – Deployed in reformers, ethylene crackers, and process gas heaters where tubes face carburizing and oxidizing atmospheres. • Metallurgical Furnaces – Protects tubes and gas paths in steel, non-ferrous, and heat treatment furnaces operating under extreme thermal conditions. • Waste-to-Energy Systems – Shields boiler tubes and superheaters from corrosive ash and high flue gas temperatures in incinerators and biomass units. • Cement and Glass Plants – Guards heat recovery and exhaust handling tubes from scaling and thermal wear in rotary kilns and regenerative chambers. Conclusion The 1Cr25Ni20Si2 Half Round Tube Shield by Ladhani Metal Corporation is engineered for high-performance protection in environments where conventional stainless steels may fail. Its exceptional resistance to oxidation, carburization, and high-temperature scaling makes it a preferred solution for boiler, furnace, and heat exchanger tube protection across several heavy industries. With customizable sizes, expert fabrication, and material certifications, Ladhani Metal Corporation delivers reliable and long-lasting shielding components designed to enhance system integrity, reduce maintenance costs, and ensure uninterrupted operation under extreme thermal stress.
