THDRF

Threaded Flange

These flanges are made of steel and are used for special applications, the major advantage of this flange is that it can be connected to the piping without welding. In certain cases, a seal weld is also used in conjunction with the threaded connection. Screwed fittings are mostly used for smaller pipe sizes. These flanges are used to connect other threaded components at low pressure.

The threaded flanges are mostly used for low pressure and low-temperature applications like water and air utility services. These flanges are inevitable in explosive areas because a welded connection in these areas would be dangerous. These flanges cannot be used with pipes that have thin walls due to the fact that thread cutting won't be possible. Threaded flanges cannot be used for conditions involving temperature or bending stresses of any magnitude. Under cyclic conditions leakage through the threads could occur in few cycles.
