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.
