An engineered high temperature resistant steelThreaded flange Revised

  • Excellent high temperature stability
  • Very oxidation and carburization resistant to 2100°F
  • Good resistance to thermal shock and quenching
  • Threaded flange features and benefits

Alloy 330 threaded flanges are specifically designed for high temperature furnace applications. Alloy 330 threaded flanges unique combination of properties allows this material to handle thermal shock from quenching, be oxidation and carburization resistant as well as handle thermal cycling well.  As a result, alloy 330 threaded flanges are found in high temperature applications like vacuum furnaces and high temperature exhaust applications.

Alloy 330 Threaded Flange Features & Benefits

combined threaded flange image

Alloy 330 threaded flanges have a tapered female thread to join the male threads of a pipe in order to create a tight seal. This type of flange is most ideal when post weld heat treatment is not possible in hazardous, flammable or explosive applications where welding is too dangerous. Alloy 330 threaded flanges are also convenient in pilot processes whose configuration is often changed.

Threaded Flange Advangtages

  • The main benefit is that that threaded seal eliminates the need for welding.
  • As they do not require welding they save time and money to install.
  • Allow for connections to be made in dangerous, explosive applications where welding is not possible.
  • Useful connection in materials that are difficult to create a successful and strong weld.
  • Ideal for connecting small diameter pipes.
  • Systems could be easily reconfigured.

Threaded Flange Disadvantages

  • They are not suitable where high temperatures, frequent cyclic conditions or bending stresses are likely in applications.
