Lubrication, Care, and Maintenance of Tube Expanders The service demanded of tube expanders is severe; therefore, these precision tools should be given a reasonable amount of care. For long, trouble-free, and economical service, the following is suggested: • Remove all rust, mill scale, and other foreign matter from inside and outside of tube. Foreign matter on the inside of the tube will tend to become embedded into the tube wall and may cause flaking or galling of the rolls and mandrel. Mill scale or grit left on the outer wall of the tube can cause damage to the tube seat and prevent the...
