ExpanTek® Model TH - 1

Tube Expansion Systems and Tooling “UNPARALLELED PERFORMANCE AND SAFETY UNDER PRESSURE!” Ball Expansion System  Pressures up to 10,000 psi (689 bar)  Hydro-mechanical ball straight line tube expansion  Cycle times as fast as 3 seconds  Single or dual operator work stations  Manufactured to customer specifications The ExpanTek® Model TH Ball Expansion System is designed specifically for hydro-mechanical straight line tube expansion applications. The components and circuitry in this system will provide reliable, repeatable expansion of tubes. The triplex hydro ball process uses water pressure to force a ball through the inside of the tube, thus expanding the tube to a desired diameter. The Model TH Ball Expansion System is powered by a threephase electric motor, and uses a belt-driven triplex pump to provide water pressures up to 10,000 psi (689 bar). The operator interface includes all necessary controls and gauges to adjust and monitor system function. The system is mounted on a skid platform, so it can be moved with a forklift to different manufacturing cells. The ExpanTek® Model TH Ball Expansion System when used with the Airmo Model 22 Series Ball Expansion Tool is easy to operate. Simply verify there is a ball in the tube prior to attaching the tool, then push the tool straight onto the tube. Next, initiate the pressure cycle by actuating the electrically operated foot switch. The system automatically forces the ball down the entire length of the tube, mechanically expanding it. Typical expansion cycles are 3 to 5 seconds, depending on tube size and length. Ball expansion tools can be quickly changed over using quick disconnect couplings. The ExpanTek® Model TH Ball Expansion System, when used with the Model 22 Series Ball Expansion Tool, provides a safe, efficient means for straight line tube expansion for boiler tube liners, condenser coils, evaporator coils, and fin/tube bonding.
