Available Grades of Inconel Flanges

Blossom Steel & Engineering Co. supplies Inconel flanges in grades selected according to the temperature, pressure, corrosion resistance, and service requirements of the application.

  • Inconel 600 Flanges
  • Inconel 601 Flanges
  • Inconel 625 Flanges
  • Inconel 718 Flanges

Types of Inconel Flanges

Different flange types are used depending on the piping connection, operating pressure, and installation requirements.

  • Inconel Weld Neck Flanges – Designed with a long tapered hub and commonly used for demanding high-pressure and high-temperature piping systems.
  • Inconel Slip-On Flanges – Fitted over the pipe and welded in place, providing a practical connection for suitable piping applications.
  • Inconel Blind Flanges – Used to close or isolate the end of a piping system, vessel, or pressure opening.
  • Inconel Socket Weld Flanges – Designed for smaller pipe sizes where the pipe is inserted into the socket before welding.
  • Inconel Threaded Flanges – Used for threaded pipe connections where welding may not be suitable for the application.
  • Inconel Lap Joint Flanges – Used with stub ends, allowing easier alignment and assembly in piping systems.
  • Inconel Ring Type Joint (RTJ) Flanges – Used in high-pressure applications where a metal-to-metal sealing arrangement is required.
