Half Round Tube Shield
Half Round Tube Shield
Half Round Tube Shields by Ladhani Metal Corporation are robust, precision-fabricated protective sleeves designed to guard the outer surfaces of tubes in boilers, heat exchangers, incinerators, and high-temperature processing equipment. Engineered to extend the service life of tubes exposed to corrosive gases, abrasive particulates, and elevated temperatures, these shields provide a reliable barrier against mechanical and chemical degradation. The half-round design facilitates easy installation while ensuring a secure, form-fitting layer of defense.
1Cr13 Half Round Tube Shield
The 1Cr13 Half Round Tube Shield is a semi-cylindrical component manufactured from martensitic stainless steel containing approximately 13% chromium. Classified under the 1Cr13 grade, this alloy delivers good corrosion resistance, excellent wear performance, and moderate strength at elevated temperatures. It is especially suited for thermal environments that are not extremely oxidizing or carburizing but where erosion and mechanical wear are a concern. With a higher hardness potential through heat treatment and moderate thermal resistance, 1Cr13 shields are ideal for applications involving flue gas exposure, soot-laden atmospheres, and temperature cycling.
The shield’s half-round configuration is precision-engineered for optimal tube coverage and long-term durability. It offers a balance of strength, corrosion resistance, and cost-effectiveness, making it suitable for a wide range of industrial processes.
