Half Round Tube Shield for LTSH Tube

Half Round Tube Shield Ladhani Metal Corporation manufactures high-quality Half Round Tube Shields designed to protect boiler and heat exchanger tubes from erosion, scaling, and thermal fatigue. These shields are especially suited for systems where tubes are exposed to turbulent gas flow, particulate-laden environments, and fluctuating thermal cycles. The semi-cylindrical shape of the shield allows easy installation and reliable surface protection, extending the operational life of the tubes. 1Cr13 Half Round Tube Shield for LTSH Tube The 1Cr13 Half Round Tube Shield is fabricated from martensitic stainless steel containing approximately 13% chromium. Known for its good corrosion resistance, moderate heat resistance, and excellent wear strength, 1Cr13 is suitable for medium-temperature applications, especially in mildly corrosive or oxidizing environments. This makes it an ideal material for shielding LTSH (Low Temperature Superheater) tubes from flue gas erosion and ash abrasion. 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 reliable manufacturer, supplier, and exporter of 1Cr13 Half Round Tube Shields, delivering durable and cost-effective solutions for various thermal power and heat exchanger applications. Chemical Composition of 1Cr13 – Martensitic Stainless Steel • Carbon (C): 0.15 – 0.20% • 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: Suitable for moderately corrosive and abrasive environments, especially in boiler systems, where mechanical strength and oxidation resistance are required at elevated but controlled temperatures. Uses • Protection of LTSH tubes in thermal power plant boilers • Surface shielding in steam generators and utility boilers • Coverage of superheater coils in flue gas-exposed zones • Suitable for coal-fired and biomass-fired boiler applications • Used in refinery and petrochemical boilers with moderate gas exposure Features • Good corrosion and oxidation resistance – Provides reliable performance in mildly corrosive environments • Wear and erosion resistance – Withstands mechanical wear from ash and soot-laden gas streams • Precise custom fitting – Fabricated to match specific tube diameters and bend radii • Enhanced tube protection – Minimizes wear on LTSH tubes, increasing overall system lifespan • Easy installation – Supports clamp-on, weld-on, and banding installation options • Wide availability – Offered in various lengths, thicknesses, and profiles Applications • power generation – Used in LTSH zones to protect from flue gas erosion and slagging • WHRBs – Shields exposed surfaces of tube bends in waste heat recovery systems • chemical and fertilizer plants – Applied in steam systems requiring moderate temperature durability • cement industry – Suitable for boilers dealing with particulate exhaust gas environments • industrial utility boilers – Enhances tube life in fluctuating thermal load zones Conclusion The 1Cr13 Half Round Tube Shield for LTSH Tube by Ladhani Metal Corporation – manufacturer, supplier, and exporter – is a dependable solution for protecting tube surfaces in moderately corrosive, abrasive, and thermally active environments.
