### Basic Principles Of Tube Expanding - Elliott Tool

Basic Principles Of Tube Expanding. Tube Expanding is the process of reducing a tube wall by compressing the outer diameter (OD) of the tube against a fixed container, such as rolling into tube sheets, drums, ferrules, or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage.
