Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are high-strength protective components used to shield boiler tubes, superheaters, and heat exchanger coils from ash impact, flue gas erosion, scaling, and corrosion. These shields are commonly used in thermal power plants, steam generating systems, and industrial boilers to protect tube surfaces and reduce wear in critical heat transfer zones. Their half-round profile is designed for easy installation and secure fitment over curved or straight tubes exposed to mechanical or thermal stress. SS 420 Half Round Tube Shield for LTSH Tube The SS 420 Half Round Tube Shield is manufactured from martensitic stainless steel grade 420, which is known for its high hardness, good oxidation resistance, and moderate corrosion protection. This material provides excellent wear resistance in abrasive and dry flue gas environments. It is particularly suitable for Low Temperature Superheater (LTSH) applications, where tubes are exposed to fly ash erosion, gas turbulence, and mechanical abrasion at relatively lower temperatures. SS 420 is often used where durability and strength are more critical than corrosion resistance alone. 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 420 Half Round Tube Shields for LTSH applications, offering reliable protection where mechanical wear and gas erosion are of primary concern. Chemical Composition of SS 420 – Martensitic Stainless Steel • Carbon (C): 0.15 – 0.40% • Manganese (Mn): ≤ 1.00% • Phosphorus (P): ≤ 0.040% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 12.0 – 14.0% • Iron (Fe): Balance Applications: Best suited for dry ash, solid particulate flow, and mildly oxidizing environments in low-temperature superheater sections of boilers and industrial furnaces. Uses • Installed on LTSH tubes to protect from fly ash abrasion and soot erosion in power boilers • Shields return bends and tube banks in HRSGs and WHRBs exposed to turbulent flue gases • Used in biomass and coal-fired boilers to prevent mechanical wear and scaling on heat transfer tubes • Suitable for zones with high solid particle velocity and moderate corrosion risk • Effective in industrial and utility boilers that operate with abrasive fuels or in dry environments Features • High surface hardness – Excellent resistance to erosion, impact, and abrasion • Moderate oxidation resistance – Performs well in clean, oxidizing gas atmospheres • Precision fitment – Custom-shaped to match tube radius and curvature for secure shielding • Simple installation – Compatible with welding, clamping, or banding methods • Cost-efficient durability – Provides long service life in mechanical wear zones • Offered in varied lengths, thicknesses, and tube diameters based on application needs Applications • thermal power plants – Installed on LTSH tubes to minimize erosion and extend operational life • waste heat recovery units – Protects lower temperature coils from particulate-laden gas streams • coal-fired boilers – Shields convection sections exposed to ash and fly particles • steam generation systems – Guards heat transfer surfaces in dry, abrasive environments • biomass plants – Prevents wear from ash and unburned particulates in combustion zones Conclusion The SS 420 Half Round Tube Shield for LTSH Tube by Ladhani Metal Corporation – manufacturer, supplier, and exporter – offers strong mechanical protection and erosion resistance for superheater and boiler tubes operating in low-temperature, abrasive environments. Designed for durability and precision fit, it enhances tube longevity and system performance in thermal applications where particulate damage is a concern.
