Half Round Tube Shield
Half Round Tube Shields by Ladhani Metal Corporation are precision-engineered protective devices used to safeguard exposed tubes in boilers, heat exchangers, steam generators, and industrial process lines. These shields are designed to reduce wear, corrosion, and thermal damage, extending tube life and optimizing system performance in harsh operational environments.
SS 316L Half Round Tube Shield
The SS 316L Half Round Tube Shield is a semi-cylindrical protective sleeve manufactured using stainless steel grade 316L. Known for its excellent corrosion resistance and low carbon content, SS 316L is particularly suited for welded applications and environments involving chlorides or acidic compounds. The reduced carbon level minimizes the risk of carbide precipitation during welding, making the shield ideal for continuous high-temperature service and corrosive process systems. Its half-round geometry allows for quick installation, offering a tight, secure fit over existing tubes without compromising system function.
Chemical Composition of SS 316L – Austenitic Stainless Steel
• Carbon (C): ≤ 0.03%
• 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
Uses
• Boiler Tube Protection – Shields boiler tubes from corrosive flue gases and thermal cycling, preventing premature failure and improving operational efficiency.
• Heat Exchanger Tube Guarding – Prevents erosion, pitting, and surface scaling in systems exposed to high-velocity fluids and temperature fluctuations.
• Marine and Coastal Installations – Used in salt-laden environments to resist chloride-induced corrosion in shipboard and offshore piping systems.
