Hastelloy B3 flanges excel in corrosion resistance, ensuring reliability with a carefully formulated chemical composition table.

Types of Hastelloy B3 Flanges:

  1. Hastelloy B3 Weld Neck Flanges: These flanges are designed with a long, tapered neck, providing excellent structural reinforcement. Weld neck flanges are commonly used in high-pressure and high-temperature applications, making them suitable for various industries, including petrochemical and chemical processing.
  2. Hastelloy B3 Slip-On Flanges: Slip-on flanges are easy to install and are often used in applications with low pressure and temperature requirements. They slide over the pipe and are then welded in place, offering a cost-effective solution for less demanding environments.
  3. Hastelloy B3 Blind Flanges: Blind flanges seal the end of a piping system or pressure vessel. They are commonly employed when the pipe needs to be closed off temporarily or when future expansion is anticipated. Hastelloy B3's corrosion resistance makes it a reliable choice for blind flanges in corrosive environments.
  4. Hastelloy B3 Socket Weld Flanges: Socket weld flanges have a socket at the bore, allowing easy and secure welding. These flanges are suitable for small-sized, high-pressure applications, and their use of Hastelloy B3 ensures resistance to corrosion in aggressive chemical environments.
  5. Hastelloy B3 Threaded Flanges: Threaded flanges are designed with threads on the bore, enabling them to be screwed onto pipes with threaded ends. Hastelloy B3 threaded flanges are advantageous in applications where quick installation and removal are required, and corrosion resistance is essential.
