Threaded
Flanges
Threaded
flanges are widely demanded as pipe flanges used in different industrial
applications. They are the special type of pipe flanges which can be
attached to the pipe without welding. Threaded flanges are threaded in
the bore which match an external thread on the pipe. These threads are
tapered in order to create a seal between the threaded flange and the
pipe as the tapers approach the same diameter. Sometimes a seal weld is
also used together with the threaded connection. They are available in
various sizes and materials.
Materials used:
- Stainless Steel
- Alloy Steel
- Carbon Steel
- Cast Iron
- Steel
- Aluminum
- Brass
- Bronze
- Monel
- PVC
- Thermoplastic etc.
How
to measure threaded flange?
Take the measurements of the following:
- O: Flange Diameter
- Q: Flange Thickness
- X: Hub Diameter at Base
- RF: Raised Face Diameter
- BC: Diameter of bolt circle
- L: Length through hub
- T: Thread Length
Key Features:
- No welding is required.
- Good for small pipe sizes.
- Should be avoided for larger loads, especially when subjected to
higher torque.
Uses of threaded flanges:
- Threaded flanges can be fitted to pipes of various sizes without
welding and this is one chief benefit for which these flanges are
highly demanded.
- They can be used in extremely high pressure applications,
particularly at or near atmospheric temperature, where the necessary
post weld heat treatment is not possible.
- They are ideal for small diameter piping applications.
- They are economical and time saving devices.
- These threaded flanges are normally designed for non-cyclic
applications.
- The flanges are suitable to be used in applications where welding
is hazardous.
- They can be used in highly explosive areas.
