How To Prevent Tubes From Rotating When Rolling
Erica Dzomba2019-11-25T14:11:44-05:00Tube rolling occurs when the tube rotates due to inadequate friction between the tube OD and the hole in the tube sheet. This can cause increased expansion times and decrease the efficiency of the operator. Increasing the friction between the tube and tube sheet and or collar the tube will not rotate within the tube sheet. Increasing the friction can be done using several different methods:
