The dimensions of the welding ring and its thickness are determined based on the standard wall thickness specifications for stainless steel pipes of the same pressure grade. If designers choose pipes with different wall thicknesses, this can be specified during selection. The outer diameter (d) of the welding ring is consistent with the outer diameter of the boss of the raised face flange. The height (h) of the welding ring primarily considers the flange thickness (C) and allows for appropriate weld seam spacing.
