Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are engineered to protect boiler tubes, heat exchanger coils, and superheaters from flue gas erosion, fly ash impact, scaling, and corrosion. These shields are widely used in power plants, industrial boilers, and waste heat recovery units to reduce tube wear, extend service life, and improve operational efficiency. Their half-round, semi-cylindrical design ensures easy installation and a secure fit over curved or straight tubes exposed to abrasive gas flow and thermal cycling. SS 430 Half Round Tube Shield for LTSH Tube The SS 430 Half Round Tube Shield is made from ferritic stainless steel grade 430, which provides good oxidation resistance, moderate corrosion protection, and excellent thermal stability. It is particularly suitable for Low Temperature Superheater (LTSH) applications where boiler tubes operate in moderately corrosive environments and are subject to ash deposition and dry gas erosion. With its high chromium content and low carbon levels, SS 430 offers a cost-effective shielding solution for boiler systems requiring dependable surface protection without the need for high nickel alloys. The Low Temperature Superheater (LTSH) is a section in a boiler where saturated steam from the steam drum is superheated to a moderately higher temperature before entering the high-temperature superheater stages. Positioned in areas with relatively lower flue gas temperatures, the LTSH helps improve thermal efficiency and reduces moisture content in steam. Due to constant exposure to abrasive flue gases and ash, LTSH tubes are prone to wear and require protective shielding, such as half round tube shields, to extend service life. Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of SS 430 Half Round Tube Shields for LTSH applications, providing durable and economical protection in moderately corrosive and thermally demanding environments. 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% • Iron (Fe): Balance Applications: Best suited for low-temperature superheater zones and convection areas where oxidation, thermal exposure, and ash erosion are concerns in boiler and steam systems. Uses • Installed on LTSH tubes to prevent scaling, ash abrasion, and flue gas corrosion • Shields tube surfaces in HRSGs, economizers, and convection zones of WHRBs • Used in industrial and utility boilers operating in dry, oxidizing flue gas environments • Suitable for coal, biomass, or oil-fired systems with moderate corrosion potential • Applied where cost-effective surface protection is required without compromising durability Features • Good oxidation resistance – Maintains integrity under sustained thermal exposure • Cost-effective – Offers a lower-cost alternative to austenitic and molybdenum-bearing steels • Custom-fit design – Precision-fabricated to match tube radius, bend geometry, and length • Easy installation – Can be installed using clamp-on, weld-on, or banding techniques • Reduces tube wear – Protects surfaces from erosion, scaling, and soot buildup • Available in multiple dimensions and thicknesses to match application specifications Applications • thermal power plants – Installed on LTSH tube banks for long-term surface protection • waste heat recovery units – Protects return bends and convection tubes from particulate erosion • steam generation systems – Applied to shield tubes in low-temperature flue zones • industrial boilers – Guards against ash impact in biomass or coal-fired heating systems • process boilers – Enhances durability of heat exchange surfaces in oxidizing environments Conclusion The SS 430 Half Round Tube Shield for LTSH Tube by Ladhani Metal Corporation – manufacturer, supplier, and exporter – offers reliable and cost-efficient protection for superheater and boiler tubes in low-temperature, oxidizing environments. Its thermal stability and erosion resistance make it ideal for power and industrial systems where long-term durability and low maintenance are essential.
