Hi, Please find below the formula for tube expansion percentage.With this you can fix the max.allowable expansion percentage in relate to the thickness of the tube after expansion. also you can find the thickness of the tube after expansion by using this formuls(Tube I after expansion! Tube " # $%.In no case it will not be less than the design thickness of the tube. The tube longitudinal and compressi&e stress shall be calculated by T') *+-.$ or -.$/. -.$/. 0ormula. 1 2 ((d$!d3% !
