Q: When do you recommend to use a threaded flange? I need a flange that can be changed easily & frequently.
A: After speaking with the customer, I found out that he has a pilot plant where he will be frequently changing parts. In this case a threaded flange is ideal because they can be frequently changed and reconfigured as they don’t require welding to install. Threaded flanges have a tapered female thread to join the male threads of a pipe in order to create a tight seal.
Benefits of Threaded Flange
1. The main benefit is that that threaded seal eliminates the need for welding.
2. As they do not require welding they save time and money to install.
3. Allow for connections to be made in dangerous, explosive applications where welding is not possible.
4. Useful connection in materials that are difficult to create a successful and strong weld.
Threaded Flange Best Practices
o They are not suitable where high temperatures, cyclic conditions or bending stresses can be potential problems.
o Ideal for where the necessary post weld heat treatment is not possible. Also best for hazardous, flammable or explosive applications where welding is dangerous.
o Ideal to connect small diameter pipes.
o Well suited for pilot processes whose configuration is often changed
