Inconel 825 Threaded Fittings
Inconel 825 Threaded Fittings Are Used in a Variety of Applications
A nickel, chromium, and iron-based alloy with molybdenum and copper additions, Inconel 825 Threaded Fittings are used in a variety of applications due to their superior properties. They are known for being highly resistant to corrosion and oxidation, making them an excellent choice for industrial environments.
They are commonly found in chemical processing equipment, oil and gas, power generation, marine, and nuclear industries. Inconel 825 Threaded Fittings are also often used in applications that require high-temperature and corrosion resistance, such as heat exchangers, pickling equipment, furnace components, and nuclear control rod release mechanisms.
The versatility of the alloy makes it a popular option for many types of fittings and valves, including weld neck flanges, socket weld flanges, forged elbows, tees, couplings, and more. These products can be produced in a number of standard sizes and pressure classes and customized to meet the specific needs of a project or system.
In addition to their corrosion resistance, 825 Threaded Fittings can also withstand high temperatures. This ability to withstand high-temperature environments is what allows them to be used in the oil and gas industry, where high temperatures are expected. They can also resist stress corrosion cracking in chloride environments, which is a common problem in these areas.
Inconel 825 Threaded Fittings Various Applications
These fittings are most commonly used in oil and gas piping systems. They are also widely used in chemical processing, marine, and aerospace applications. Their corrosion resistance makes them ideal choices for these types of applications, where they are exposed to harsh chemicals and gasses.
Alloy 825 Forged Fittings are used to join pipes in a plumbing system. They are typically used to join tubes with a thin wall and are ubiquitous in systems that need regular disassembly for maintenance work. They are a popular alternative to compression fittings, as they do not require soldering and are easier to install.
