1300 Tube expander for small coolers

KRAIS 1300 series expanders are designed for small tubing applications where additional reach and a longer roll zone are required. They are well suited for thick tube sheets and deeper seating geometries, where standard reach may be limited. These tools are commonly used on small coolers, particularly during service and retubing work, where tube access, sheet depth, and joint geometry determine the need for extended reach.

Applications

Small heat exchanger retubing in chemical processing plants
Auxiliary cooler maintenance in oil and gas refineries
