Incoloy 825 Tubes applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Chemical applications: Incoloy 825 tanks are widely used in the chemical industry to handle corrosive chemicals such as sulfuric acid, phosphoric acid, nitric acid, and other acids that require resistance to environmentally producing oxidizing and reducing processes. They are used in reactors, heat exchangers, and piping systems.
Oil and Gas: Incolys are used in downhole and surface applications in the oil and gas industry. They include tubing and piping in oil and gas wells and acid gas production due to their resistance to sulfide stress cracking. Also used in equipment is chloride stress corrosion cracking.
Petrochemicals: Incoloy 825 tubes are used in a variety of petrochemical applications such as heat exchangers, condensers, reactors and piping systems where corrosion resistance is essential to acid, base and chloride solutions
Desalination: Incoloy 825 tubes are used in desalination plants to resist chloride stress corrosion cracking and pitting in seawater environments. They are commonly used in heat exchangers and evaporators in thermal reverse osmosis desalination processes.
Power processing: Incoloy 825 cables find applications in the electrical industry, especially in water heaters, heat exchangers and boiler systems, where they provide resistance to corrosion under high temperature, high pressure and acidic conditions
Water Resistance: Incoloy 825 is known for its exceptional corrosion resistance in various environments, including acid, alkaline and seawater. Check the corrosion of the environment in which pipes will operate and ensure that Incoloy 825 is consistent with the presence of decomposition products.
Temperature and Pressure: Specify the temperature and pressure the pipe in your application will reach. Incoloy 825 exhibits excellent mechanical properties at room temperature and high humidity, making it suitable for high-temperature and high-pressure applications
Mechanical properties: Consider the necessary mechanical properties for your application, including absorption, capacitance, and length. Incoloy 825 provides high strength and excellent flexibility, which is necessary to withstand mechanical stresses and avoid premature failure.
Size and Dimensions: Select the appropriate tube size and dimensions based on your system’s needs, including diameter, wall thickness, and dimensions. Ensure that the tubes selected meet the dimensional specifications necessary to fit and function with your equipment.
Weldability: If your application involves welding, consider the weldability of the Incoloy 825 tube. Incoloy 825 can be easily welded using conventional welding techniques, but it is important to follow proper welding procedures to maintain the product’s corrosion resistance and mechanical properties.
Incoloy 825 tubes offer excellent corrosion resistance, mechanical properties, and reliability, making them cost-effective for applications where longevity and performance outweigh initial investment. While they may have a higher upfront cost compared to some alternatives, their durability and reduced maintenance requirements often result in long-term savings.
Yes, Incoloy 825 tubes typically adhere to standards such as ASTM B423/B163 for seamless tubes and ASTM B704/B751 for welded tubes. These standards specify dimensions, mechanical properties, and testing procedures to ensure quality and compatibility with various industrial applications.
Incoloy 825 tubes are available in various configurations, including seamless and welded options. Common configurations include straight lengths, coils, and U-bends. They can also be customized with different wall thicknesses, diameters, and lengths to suit specific application requirements in industries such as chemical processing, oil and gas, and power generation.
Incoloy 825 tubes can experience galvanic corrosion when in contact with dissimilar metals in certain environments. However, their inherent resistance to corrosion, including in aggressive conditions, mitigates this risk. Proper material selection and design considerations can further minimize the potential for galvanic corrosion in specific applications.
