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.
