These shields are critical for reducing erosion, oxidation, and thermal degradation, particularly in high-temperature zones where process gases, flames, or particulate matter can damage tube integrity over time. 1Cr20Ni14Si2 Half Round Tube Shield The 1Cr20Ni14Si2 Half Round Tube Shield is a semi-cylindrical protective sleeve manufactured from a high-performance austenitic stainless steel alloy consisting of approximately 20% chromium, 14% nickel, and 2% silicon. This alloy is designed for excellent oxidation resistance, carburization resistance, and high-temperature structural stability. The inclusion of silicon significantly enhances the formation of a protective oxide film, making it suitable for use in severe thermal environments such as industrial furnaces, superheaters, and reformers. The shield’s half-round profile is engineered for easy installation over the tube surface, ensuring a tight, durable fit and long-term protection. Chemical Composition of 1Cr20Ni14Si2 – Austenitic Heat-Resistant Stainless Steel • Carbon (C): ≤ 0.15% • Silicon (Si): 1.50 – 2.50% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Chromium (Cr): 19.0 – 21.0% • Nickel (Ni): 13.0 – 15.0% • Iron (Fe): Balance Uses • Boiler Tube Protection – Shields critical areas of superheater and reheater tubes from oxidation and scale formation under high flue gas temperatures. • Furnace Tube Shielding – Guards against flame impingement, high-temperature corrosion, and mechanical erosion in radiant and convection zones. • Heat Exchanger Cladding – Offers external protection for tubes subjected to thermal shock and corrosive process gases. • Steam Reforming Equipment – Prevents surface degradation of tubes in syngas and hydrogen production systems operating under carburizing conditions. • Waste Heat Boilers and Incinerators – Provides a thermal barrier for tubes exposed to particulate-laden gas flows and fluctuating temperatures. Features • Excellent Oxidation Resistance – High chromium and silicon content form a dense, protective oxide layer for long service in oxidizing environments. • Carburization and Thermal Fatigue Resistance – Suitable for prolonged use in atmospheres containing hydrocarbons, CO, and high radiant heat. • High-Temperature Durability – Retains strength and resists creep deformation at service temperatures up to 1000°C. • Austenitic Microstructure – Offers superior ductility, resistance to cracking under thermal cycling, and excellent metallurgical stability. • Easy Installation – Half-round configuration allows for fast on-site fitment using mechanical clamping or welding, with minimal tube disruption. • Surface Finishing Options – Available in pickled, passivated, or bright annealed finishes for improved corrosion and heat resistance. • Custom Built – Manufactured to meet specific size, thickness, and design requirements for varied industrial applications. Applications • Thermal Power Plants – Used to protect boiler tubes in high-temperature zones like superheaters, economizers, and air preheaters. • Petrochemical and Refining Plants – Deployed in furnace tubes, reformer systems, and transfer line exchangers where oxidation and carburization are concerns. • Waste-to-Energy Systems – Protects boiler and heat recovery tubes from corrosive gas attack and ash erosion in incinerators. • Metallurgical Furnaces – Applied in annealing, forging, and reheating furnaces for protecting tube walls exposed to high heat and corrosive gases. • Cement and Lime Kilns – Shields heat recovery piping and cooler tubes from abrasion and elevated thermal conditions. • Chemical Process Equipment – Guards steam and process tubes in reactors, condensers, and exchangers from scaling and thermal damage.
