Series related information

applications.

The various types of threaded flanges are as follows:

  • Plain Threaded Flanges

  • Female Threaded Flanges

  • Male Threaded Flanges

No welding is required.

Threaded Flanges can be used in very high pressure services and their major advantage is that they can be assembled without welding.

Uses of threaded flanges :

Threaded flanges are threaded in the bore which match an external thread on the pipe. Threaded flanges are used with pipes that have external threads. The benefit of these flanges is that it can be attached without welding.

  • 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.

Details of Threaded flange
They are the special type of pipe flanges which can be attached to the pipe without welding.
