What is a Threaded flange?
Threaded pipe flanges are the special type of flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which matches an external thread on the pipe. Threaded pipe flanges is just like to slip-on pipe flanges that are used with pipes that have external threads.

Advantages of THD 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.
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.
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.
