Pneumatic hydraulic tube expander is composed by hydraulic system, control system, expanding lumen, expanding rod and other components, which has the advantages of low labor intensity, high production efficiency; expanding quality uniform and reliable; expanding medium without pollution to the expansion pipe joint; residual stress; tube plate heat exchanger can be arbitrary for full thickness expansion; hydraulic expansion can not only ensure the expansion quality, prolong the life of the heat exchanger, but also improves the work efficiency, reduce labor costs.
l Powered by 3-8 bar compressed air
l Applicable to the tube sheet of thickness 10-400mm
l Equipped with PLC module and Touch screen, easy to operate
l Maximum output pressure 800bar, and the pressure value can be preset in touch screen
l Pressure holding time can be preset to ensure the tube expanding effect.
l Low residual stress , and the gap corrosion is not easy to happen
l The expansion joint is free of pollution, the first expansion after welding is not affected.
l Capable of operation continuously , expanding speed 5- 10 tubes each minute
