Re: [MW:20165] Tube Expansion formula

Tube Thinning calculation
Actual % Tube wall Thinning  = [(WTb-WTa)/WTb]  X 100
WTb-Tube Wall Thickness before expanding = (Do-db)/2, Wta=Tube Wall Thickness after expanding=(Dh-da)/2
da=Tube ID after Expansion,db=Tube ID before Expansion,Dh=Diameter of tube Hole,Do=  OD of Tube.
Sl No	Tube OD (DO) mm	Tube ID (db) mm	Tube ID after Expansion(da) mm	Hole Size (Dh) mm	% WallThinning	Remarks
1	42.54	33.07	33.84	42.71	6.34
2	42.55	33.08	33.90	42.70	7.07
