The invention involves a procedure for designing a reinforcement ring (1), which is placed between and with welding seams welded to the side of a running header pipe (2) and the end of a branch pipe (3) which reinforcement ring (1) has a saddle formed end against the header pipe with a pair of opposed ears (13) and a pair of opposed crotches (12) by which the welding seam between the reinforcement ring (1) and the header pipe (2) and the consumption of material for production of the reinforcement ring (1) are optimized to the smallest possible volumes. The invention also involves a characteristic formed end of the reinforcement ring (1) against the header pipe (2), by which form the volume of the welding seam is minimized.
