ExpanTek Model 30 Series Tube Expansion Tool

ExpanTek® Model 30 Series Tube Expansion Tools - Up to 10,000 psi (689 bar)

The patented ExpanTek Model 30 Series Tube Expansion Tool is a precision-machined tool providing versatility for use in hydro-expansion applications. The tool is designed for high-pressure expansion of tubing or pipe. Using this unique tool along with a high-pressure power source, such as the ExpanTek® Model HPS Hydrostatic Pressure System, will rapidly expand tubing for boiler coils, refrigeration coils, and tubular assemblies.

The Model 30 Series Tool is a snap-on coupling suitable for hydro-expansion of tubes with standard OD tolerances and maximum working pressure up to 10,000 psi (689 bar).

To hydro-expand a tube, attach the Model 30 Series Tool with optional NuQuip® Automatic Air Bleed Valves 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 the maximum pressure rating of the tool. After the tube is expanded and the service line pressure drops to 0 psi/bar, the collets automatically release; allowing quick removal of the tools from the work piece.

The Model 30 Series Tool can handle standard and metric tube and fitting sizes from 0.13 in. to 1.00 in. (3.2 mm to 25.4 mm) in diameter.
