ExpanTek® Model 30 Series Hydro-Expansion Tools - Up to 10,000 PSI (690 BAR)

The patented ExpanTek® Model 30 Series Hydro-Expansion Tool is a precision- machined tool providing versatility for use in
hydro-expansion applications.
This tool is designed for high-pressure expansion of tubing or
pipe. Using this unique tool along with a high-pressure system unit, will
rapidly expand tubing for refrigeration coils, boilers, tubular
assemblies, and many other associated products. Its
short, outside collet grip accommodates applications with
short tube ends. The deep tube swallow allows for long
non-expanded tube length.
The Model 30 Series tool can handle English and metric tube
and fitting sizes from 0.125” to 1.000” (3.175 mm to 25.40 mm) in diameter. Special
sizes and configurations will be considered upon request.
The Model 30 Series is a snap-on coupling suitable for hydro-expansion
on a tube with standard OD tolerances needing expansion pressures up to 10,000 PSI (690 BAR).
For hydro-expansion, attach the Model 30 Series tool with optional
NuQuip® Automatic Air Bleed to one end of the tube. Adapt the
second Model 30 Series Tool to a pressure service line, and slip it
over the remaining end. Press both tools firmly against the
internal stop. When the service line is pressurized to 50
PSI (3.45 BAR), the collets are activated for a positive grip. Continue
to pressurize the tube until expansion pressure is reached.
Use caution not to exceed maximum pressure rating of the
tool. After the tube is expanded and the service line pressure
drops to 0 PSI, the collets automatically release; allowing
quick removal of the tools from the work piece.
