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. Although available in most sizes and pressure rating, threaded flanges today are used almost exclusively in smaller pipe sizes. Threaded flanges are not suitable for piping with thin wall thicknesses because cutting a thread on the pipe is not possible.
KSN can supply forged threaded flanges by all kinds of materials according to customer’s drawings and technical requirements.
The heat treatment and surface treatment for forged flanges will be performed according to customer’s requirements.
