Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered components used to protect boiler and heat exchanger tubes from erosion, scaling, and high-temperature corrosion. These shields are widely applied in industrial systems exposed to thermal cycling, aggressive gases, and particulate flow. Their half-round shape allows for simple and secure installation over straight or curved tube surfaces, extending tube life and reducing maintenance needs. SS 316 U Type Half Round Tube Shield The SS 316 U Type Half Round Tube Shield is specifically designed to protect U-bend sections in superheaters, reheaters, and heat exchanger coils. Manufactured from SS 316, a molybdenum-bearing austenitic stainless steel, it offers enhanced resistance to pitting, crevice corrosion, and chloride-induced attack. The U-type design ensures precise coverage over tube bends, where erosion and heat damage are most intense. Both inner and outer U configurations are available for comprehensive protection. • Outer U Type Half Round Tube Shield – Protects the outer curvature of the U-bend from flame impingement, slag buildup, and high-velocity gas erosion. • Inner U Type Half Round Tube Shield – Shields the inner arc of the bend against turbulence-induced wear, localized corrosion, and scaling. Ladhani Metal Corporation is a trusted manufacturer and exporter of SS 316 U Type Half Round Tube Shields, delivering high-performance solutions for industries requiring superior corrosion resistance and heat tolerance. Chemical Composition of SS 316 – Austenitic Stainless Steel with Molybdenum • Carbon (C): ≤ 0.08% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.045% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 16.0 – 18.0% • Nickel (Ni): 10.0 – 14.0% • Molybdenum (Mo): 2.0 – 3.0% • Iron (Fe): Balance Applications: Best suited for environments with exposure to chlorides, steam, and acidic gases, where resistance to corrosion and heat is critical. Uses • Protection of U-bend tubes in high-temperature boiler coil sections • Shielding tube bends in chemical heat exchangers and steam reformers • Coverage for WHRB tube bends exposed to abrasive flue gas streams • Safeguarding curved tubes in condensers, superheaters, and evaporators • Ideal for corrosive and chloride-laden environments in marine or coastal installations Features • Excellent corrosion resistance – Made from SS 316 with molybdenum, offering superior protection against pitting, crevice corrosion, and acidic gas exposure. • High-temperature performance – Performs reliably in high-heat environments, withstanding oxidation and thermal stress during prolonged operation. • Dual-side coverage – Available in both inner and outer U-type configurations for full protection of return bends in heat exchanger and boiler systems. • Precision fitment – Custom-fabricated to match tube radius and diameter for a tight, secure fit that prevents movement and surface exposure. • Easy to install – Designed for quick and secure mounting using clamps, tack welds, or banding without requiring system disassembly. • Custom dimensions – Available in a wide range of lengths, thicknesses, and tube radii to meet exact design and performance requirements. Applications • thermal power plants – Used on U-bend tubes in superheaters and reheaters to resist flue gas corrosion and scaling. Enhances service life and reduces downtime in high-temperature zones. • petrochemical plants – Shields tube bends in steam reformers and exchangers exposed to chlorides and process gases. Provides robust corrosion protection in aggressive chemical environments. • waste heat recovery systems (WHRBs) – Protects curved tubes in exhaust gas streams from slag erosion and thermal shock. Improves long-term durability under fluctuating temperatures and gas flow. • chemical and fertilizer industries – Installed on tube bends in reactors and ammonia reformers for corrosion and erosion resistance. Helps prevent pitting and degradation from acidic and chloride-containing media. • HRSGs and industrial boilers – Used in return bends to prevent surface scaling and heat-induced fatigue. Maintains structural integrity and energy efficiency in cyclic operating conditions.
