Tube Expansion of Shell and Tube Heat exchanger #chatgpt

Carbon steel and SA179 tube of 3/4 inch size expansion process in Rohan industries pune MAharashtra India
Formula for Tube Expansion
how to calculate tube expansion percentage
EXPANSION GAUGE REPORT


Do =Tube ID after Expansion to calculate
D1 =Tube Hole Dia 19.2 to19.35 ( take higher limit )
T =Average thickness of tube 2.33 thk
K =% Thinning to specify

SR. Thinning by 6% Thinning by 7% Thinning by 8%


1 Do =(K x 2T)100 + D1 - 2T Do =(K x 2T)100 + D1 - 2T Do =(K x 2T)100 + D1 - 2T
=(6x2x2.33)/100+19.34-(2x2.33) =(7x2x2.33)/100+19.34-(2x2.33) =(8x2x2.33)/100+19.34-(2x2.33)
= 0.28 + 19.34 - 4.66 =0.33+19.34-4.66 =0.37+19.34-4.66
= 14.96 mm =15.01 mm =15.05 mm

Torque :- 265 Nm Torque :- 355 Nm Torque :- 440 Nm


expansion formula = [% of thinning x (2 x thk of tube)+ tube hole size - 2xthk of tube]

% thinning 2xthk of tube by 100 tube hole size 2 times thk value
11 2 3.25 100 25.75 2 3.25 19.965
9 2 3.25 100 25.73 2 3.25 19.815
8 2 3.25 100 25.75 2 3.25 19.77
7 2 3.25 100 25.73 2 3.25 19.685
6 2 3.25 100 25.75 2 3.25 19.64
5 2 3.25 100 25.75 2 3.25 19.575
