Threaded flanges (TH flanges)

Threaded flanges (TH flanges) are widely demanded as pipe flanges i.e called as threaded 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.

Uses of threaded flanges (TH flanges):

Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these threaded flanges (TH 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 (TH flanges) are normally designed for non-cyclic applications.

The threaded flangess (TH flanges) are suitable to be used in applications where welding is hazardous.

They can be used in highly explosive areas.
