Silver Tubes is the #1 Inconel 825 pipes and tubes manufacturer and supplier in Mumbai, India. We provide reliable solutions for industries needing superior heat and corrosion resistance. Engineered for high-temperature applications, our Inconel 825 pipes and tubes deliver excellent mechanical strength and oxidation resistance. Whether handling high-temperature applications or aggressive chemical exposure, our Inconel 825 pipes and tubes deliver long-lasting performance.
What makes Inconel 825 stand out is its carefully balanced chemical composition. It contains 38-46% nickel, a minimum of 22% iron, 19.5-23.5% chromium, 2.5-3.5% molybdenum, 1.5-3% copper, and 0.6-1.2% titanium, along with trace amounts of carbon, manganese, sulfur, silicon, and aluminum. This mix makes it very resistant to sulfuric and phosphoric acids, and the molybdenum and copper make it even more resistant to harsh, corrosive environments. The addition of titanium stabilizes the alloy, making it highly resistant to intergranular corrosion after welding.

To meet diverse industry needs, we offer Inconel 825 tubes and pipes in various sizes, thicknesses, and lengths. Standard length options include single random (4–7 meters), double random (7–13 meters), and custom-cut lengths to suit project specifications. Outer diameters range from 6mm to 610mm for pipes and 1mm to 254mm for tubes, with wall thicknesses between 1mm and 20mm. Depending on the application, we provide surface finishes such as polished, bright annealed, pickled, and sandblasted, ensuring durability and aesthetic appeal.
Our Inconel 825 pipes and tubes are available in round, square, rectangular, and hydraulic forms, making them versatile across various industries, including offshore oil rigs, chemical plants, power generation, and marine engineering. Seamless pipes are best suited for high-pressure and high-temperature conditions, while square and rectangular tubes are commonly used in structural frameworks. Every product undergoes strict quality checks, including hydrostatic, ultrasonic, and Positive Material Identification (PMI) testing, to ensure reliability and performance.
