Tube Expander Lubrication, Care, and Maintenance The service demanded of tube expanders is severe, therefore, these precision tools require a reasonable degree of maintenance. For long, trouble-free, and economical service, we suggest: 1. Remove all rust, mill scale, and other foreign matter from the inside and outside of the tube. Foreign matter on the inside of the tube will become imbedded in 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 formation of a...

Guidelines for Tube Expansion Unproperly rolled joints create considerable additional expense: under-rolled joints must be re-rolled, and over-rolled tubes must be removed and replaced. The optimum joint is one that develops a leak-tight joint with adequate strength for the intended service, but with the minimum amount of cold working (or tube wall reduction). Here is an example of the application of this method for a 2-inch Outer Diameter 10 Gauge tube in a boiler. 2.010 Tubesheet Hole: __________ -2.000 Tube Outer Diameter : __________ .010 Clearance: __________ 1.732 Tube Inner Diameter...
