Types of Carbon Steel Threaded Flanges

This type of flange features a threaded inner bore, allowing it to be easily connected to threaded pipes or fittings. It is slipped onto the pipe end and then secured by tightening the threaded connection. Threaded slip-on flanges are commonly used in low-pressure applications. Threaded weld neck flanges have a tapered hub with internal threads that provide a strong and durable connection.

  • Threaded Companion Flange: This type of flange is designed to be used in conjunction with another flange to create a connection between two pipes or fittings with different end types.
  • Threaded Blind Flange: Threaded blind flanges are solid disks with threaded bores. They are used to close off the end of a piping system, providing easy access for maintenance and inspection.
  • Threaded Socket Weld Flange: Threaded socket weld flanges have a socket-like bore that fits over the pipe's outer diameter.
  • Threaded Weld Neck Flange: Threaded weld neck flanges have a tapered hub with internal threads.
  • Threaded Slip-On Flange: This type of flange has a threaded inner bore and is slipped over the pipe end.

Features of Carbon Steel Threaded Flanges

  • Threaded carbon steel flanges are compatible with threaded pipes and fittings, providing versatility in connecting different components within a piping system.
  • The threaded connection allows for straightforward installation without the need for welding or specialized equipment.
  • When properly tightened, threaded carbon steel flanges create a tight and secure seal, minimizing the risk of leaks and ensuring the integrity of the piping system.
  • Carbon Steel steel is known for its excellent strength and resistance to high temperatures and pressures.
  • Carbon Steel steel construction provides durability and reliability, ensuring long-term performance and minimizing the need for frequent replacements.
