Half Round Tube Shield Ladhani Metal Corporation manufactures precision-engineered Half Round Tube Shields to protect boiler and heat exchanger tubes from corrosion, erosion, and surface degradation. Designed for durability in aggressive environments, these shields are especially suited for thermal equipment where tubes are subjected to high flow velocities, abrasive particles, and flue gas turbulence. Their half-round shape allows easy installation while offering long-term protection and reduced maintenance. 1Cr20Ni14Si2 Half Round Tube Shield for LTSH Tube The 1Cr20Ni14Si2 Half Round Tube Shield is manufactured from a high-temperature-resistant chromium-nickel-silicon alloy. With approximately 20% chromium, 14% nickel, and added silicon, this material offers outstanding oxidation resistance, excellent strength at elevated temperatures, and superior resistance to high-temperature corrosion. It is an ideal choice for shielding Low Temperature Superheater (LTSH) tubes, which are frequently exposed to flue gases carrying ash and particulate matter that can cause rapid wear.
