Description
^ upHydraulic expansion is the direct application of high internal hydraulic pressure within a tube in order to form a tight joint between the tube and tube sheet. This expansive force is accurately set, measured, repeated, and controlled.
The HPX and JR7 Series Tube Expanders are air driven hydraulic systems capable of producing expansion pressures up to 88,000 psi (6,000 Bar). When used in conjunction with HydroPro High Pressure Tooling, these systems offer the very best in tube expansion solutions.
The panel mounted LED's follow the expansion process through each complete cycle (indicated with green lights) Any failure to achieve or maintain expansion pressure or time is identified on the panel with a red light at the point of failure.
Features

HPX 7000 System
The HPX 7000 System is HydroPro's nuclear grade expansion system. It includes all of the same features as the HPX 6050 along with full material traceability, membrane switch controls, and multiple available options often required in Nuclear fabrication or other high documentation applications. Additional options include system controlled multi-stage expansion, gun mounted transducer, and operation via touchscreen tablet. The system is also available with ultra-high pressure output of 72,500 psi with the HPX 7070 model.
JR7 System
The HydroPro JR-7 hydraulic expansion system offers users the most versatile tube expansion system in the world, with a 58,000 psi output in a lightweight, open frame package. The system features a digital pressure readout, LED cycle indicators, sturdy steel frame construction, electronic gun, and industrial casters, this system has become the workhorse for top heat exchanger manufacturers around the world. The JR-7 is currently used in more than 30 countries for day-to-day tube expansion needs.
