Technical Specifications

The document includes extensive tabulated data correlating tube outer diameter (O.D.), tube thickness (in BWG and inches), tube projection over roll, tube sheet thickness, and corresponding tool model numbers.

• Tube O.D. Range: From 1/2 inch up to 4 1/2 inches and beyond.
• Tube Thickness: Specified in both BWG (Birmingham Wire Gauge) and inches, ranging from approximately 0.035 inch to 0.284 inch.
• Tube Projection Over Roll: Values given in inches, indicating how far the tube projects over the roll during expansion.
• Tube Sheet Thickness Range: Categorized into ranges such as 1/2" to 7/8", 3/4" to 1 1/8", 1 1/8" to 1 5/8", 1 5/8" to 2 1/8", and 2 1/8" to 2 5/8".

Model Numbering and Tool Selection

The tables provide specific model numbers for tube expanders, mandrels, and roller sets corresponding to tube dimensions and sheet thickness ranges. These include:

• Tube Expander Model Numbers (e.g., A-31/2, A-49/5, A-100/6).
• Spare Mandrel Model Numbers (e.g., 15-2-RS, 30-6-RS).
• Spare Roller Set Model Numbers (e.g., DM-11, HM-13, SM-13).
• Mandrel sets are identified by the number of mandrels and square drive size.

Usage Recommendations

• Use the tool models matched to the tube O.D., thickness, and tube sheet thickness for optimal expansion without flaring.
• Refer to the mandrel and roller set numbers for maintenance and replacement parts.
• The tool is suitable for applications requiring economical and durable tube expansion.
