Threaded Flanges

Threaded Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding.  Sometimes a seal weld is also used in conjunction with the threaded connection.  This special type of flange is generally used for high pressure piping system, yet smaller diameter applications.  This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges’ pressure applications. Threaded flange use in low press condition usually.
