Hydraulic tube expansion tool 35

for the aeronautical industry

The patented ExpanTek® Model 35 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 tubes. Using this unique tool along with a high-pressure power source, such as the ExpanTek® Model HPS Hydraulic Power Supply, will rapidly expand tubing for boiler coils, refrigeration coils, and tubular assemblies. The Model 35 Series Tool is a snap-on coupling suitable for hydro-expansion of tubes with standard OD tolerances and maximum working pressure up to 15,000 psi (1,034 bar). To hydro-expand a tube, attach the Model 35 Series Tool with optional NuQuip® Automatic Air Bleed Valves to one end of the tube. Adapt the second Model 35 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 35 Series Tool can handle standard and metric tube and fitting sizes from 0.24 in. to 1.00 in. OD (6.0 mm to 25.4 mm OD) in diameter. Maximum Pressure: - Working pressures up to 15,000 psi (1,034 bar) Tube OD Range: - 0.24 in. to 1.00 in. OD (6.0 mm to 25.4 mm OD) Temperature: - 32° F to 120° F (0° C to 49° C) Services: - Water, oil, and other liquids on request Collet Grip: - On tube OD
