 Rolled Groove
One or more grooves may be employed to increase turbulence of a fluid passing through the tube, thereby improving thermal transfer. The groove may also be used to locate other components inside the tube or provide a means for retention of subsequent assemblies. Due to work hardening in the groove area, ductile materials and tempers should be specified.
