The water expansion machine can be quickly plugged in and out of the heat exchange tube, and ensures safe sealing with the heat exchange tube under high pressure.
The working pressure can reach 2068Bar, and the tube diameter range is 3.2-28.6mm.
Compared with mechanical push/pull expansion:

※ High efficiency - especially suitable for hard materials and non-straight tubes
※ Reduced operation process - no need for degreasing, no need for tube end expansion
※ Good expansion quality - uniform wall thickness reduction, minimal tube shrinkage
※ Single-person operation - low labor intensity
