UNS S32750 Super Duplex 2507 Pipe Specifications

Super Duplex 2507 Pipe is a combination of 25% Chromium, 4% Molybdenum, and 7% Nickel. The addition of Copper acts as a corrosion-resistant layer and enhances the overall strength of the metal. The pipe also contains small amounts of Nitrogen and Tungsten, which further enhances its corrosion resistance.

Super Duplex 2507 Pipe can be produced in either welded or seamless form. Welded pipes are primarily used for oil and gas applications, whereas seamless pipes are commonly used in the petrochemical and offshore industries. The production process for Super Duplex 2507 Pipe involves hot rolling, cold rolling, and cold-drawing techniques. The pipe is then annealed and quenched to achieve the desired mechanical properties.

When it comes to the mechanical properties of Super Duplex 2507 Pipe, it has an impressive yield strength of around 80 ksi, which is much higher than standard duplex grades. It also has a tensile strength of around 116 ksi, which is one of the highest among all duplex grades. This pipe's high strength makes it suitable for use in high-pressure applications.

Super Duplex 2507 Pipe has excellent resistance to various types of corrosion such as pitting, crevice attack, and stress corrosion cracking. It is highly resistant to seawater, chloride solutions, and acidic environments. The pipe also maintains its corrosion resistance at high temperatures, making it suitable for use in high-temperature applications.

In conclusion, Super Duplex 2507 Pipe is a highly reliable and excellent quality pipe with high mechanical and corrosion resistance properties. It is widely used in various applications, including offshore oil and gas, chemical processing, power generation, and more. ASTM A789, ASTM A790, and ASTM A928 are the primary standards used for Super Duplex 2507 Pipe production, and the pipe can be manufactured in both welded and seamless forms to meet different requirements. Its impressive mechanical properties and resistance to corrosion make it an excellent choice for use in highly corrosive environments.
