'prevent stress cracking'

Ladhani Metal Corporation offers Half Round Tube Shields specially designed for refinery heaters, where tubes are exposed to extremely high operating temperatures, flue gas velocity, and abrasive particle erosion. These shields act as a protective barrier, preventing tube surface wear, oxidation, and localized damage in the radiant and convection sections of refinery heaters. By absorbing erosive and thermal stress, Half Round Tube Shields extend tube service life, reduce maintenance downtime, and improve heater reliability. Function of Tube Shields in Refinery Heaters • Protect heater tubes against erosion, oxidation, and scaling • Reduce wear in high-flue-gas velocity zones and flame-impinged areas • Extend tube lifespan under continuous high-temperature service • Improve refinery heater efficiency and minimize shutdown frequency Ladhani Metal Corporation manufactures, supplies, and exports Half Round Tube Shields in refinery-grade stainless steels and heat-resistant alloys, offering custom sizes to meet specific heater configurations. Available Grades • SS 304 / SS 304L • SS 310 / SS 310S • SS 316 / SS 316L • SS 410 / SS 420 / SS 430 • 1Cr13 • 1Cr18Ni9Ti • 1Cr20Ni14Si2 • 1Cr25Ni20Si2 • Cr23Ni13 • Cr25Ni20 Applications: Used in refinery heaters, petrochemical furnaces, process gas heaters, and other fired equipment requiring tube surface protection against oxidation, erosion, and flame impingement. Uses • Shields radiant section tubes from high-temperature scaling • Protects convection section tubes against flue gas erosion • Extends operational life of refinery heater components • Provides reliability under continuous refinery operating cycles Features • Excellent high-temperature oxidation resistance • Strong mechanical strength under thermal cycling • Precision-formed to match tube curvature for complete coverage • Available in stainless steel and heat-resistant alloy grades Applications • Refinery fired heaters – Protects radiant and convection section tubes • Petrochemical process furnaces – Guards against erosive and thermal wear • Thermal cracking and reformer heaters – Enhances tube longevity • Industrial fired heaters – Suitable for high-temperature corrosive atmospheres Conclusion Half Round Tube Shields for Refinery Heaters by Ladhani Metal Corporation deliver reliable, export-quality protection for tubes operating under extreme refinery service conditions. Available in stainless steels and special alloys, these shields are engineered to enhance efficiency, reduce erosion damage, and extend heater tube service life.

LADHANI METALA CORPORATION Stainless Steel 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L also provides resistance to sensitization when welded and higher creep, stress to rupture, and tensile strength at elevated temperatures. It is non-magnetic in the annealed condition but may become slightly magnetic after welding.Since our establishment, we have become the well-known manufacturer, exporter and supplier of a high quality array of SS 317L Fittings. The offered range is manufactured by utilizing high grade raw material and advance technology by our skilled professionals. Apart from this, our range is tested on various parameters in order to ensure its durability and quality. Clients can avail these products from us in different specifications and at affordable prices. Features: Durability Finally finished Anti-corrosive RANGE : 15NB-1200NB. SCH:5, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, XXS. TYPE : Elbow: 45, 90 & 180Deg. Radius. Tee: Equal & UnEqual. Bend: Short & Long Radius. 1.5D, 2.5D, 3D, 5D, 6D, 10D.

LADHANI METAL CORPORATION Stainless 321 is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000°-1600°F temperature range. 321 stainless is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800°-1500°F. Type 321 is similar to type 304 stainless but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in the 800°-1500°F service conditions. In order to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking in service temperatures at 1500°-1650°F an air cool may be used.Since our establishment, we have become the well-known manufacturer, exporter and supplier of a high quality array of SS 321 Fittings.
