Overview: The document provides technical specifications for tube expanders, specifically the 1200 Series Long Reach models. These expanders are used for heat exchangers and condensers with tubes ranging from 5/8” to 1.1/2” O.D. and thick tube sheets. The document details the different models, their specifications, and the corresponding mandrel drives.

Specifications:

• Model 1197-1256 expanders are equipped with 3/8” square mandrel drives.
• Model 1257-1300 expanders come with 1/2” square mandrel drives.
• The expanders are fitted with rollers of varying lengths, including 1.1/2” (38.1mm) and 2.1/4” (57.15mm).
• Tube O.D. ranges from 8.4 mm (.334”) to 36.3 mm (1.43”).

Procedures and Usage:

• The expanders are designed for use in heat exchangers and condensers, providing a popular tool worldwide for these applications.
• Longer reach expanders are available upon request, with adjustable ranges for tube sheet applications.

Data Summary:

• The document includes detailed tables listing tube O.D., thickness, I.D., and the corresponding tool numbers, mandrel numbers, and roller set numbers.
• Each entry specifies the minimum I.D. the tool enters and the maximum expansion of the tool.

Recommendations:

• For specific applications, users should select the appropriate model based on the tube size and required expansion capabilities.
• Consider the reach needed for the application and request longer reach expanders if necessary.
