Hydro-Pel® is a method of tube expansion which places a projectile, usually a ball, into a tube with water pressure forcing the ball through the tube. Generally, the amount of expansion is a function of the ball diameter and the tube wall thickness. This method is suggested where straight length tubes are used with one operator performing the expansion.
For applications in which tube belling is performed as a standard operation, conventional ball expansion methods are used. The operator places a ball into the tube and places an expanding tool over the tube end and starts the system pressure cycle. High pressure water is directed behind the ball, forcing it down the tube.
Airmo's patented Hydro-Pel® Pressure Systems are designed to mechanically
expand heat exchanger tubing reliably and
efficiently. There is no setup
required for different tube
configurations on the coils as
the tubes are expanded
individually using a steel ball. Water at a high
pressure is used to force a
ball, larger than the tube ID,
through the tube expanding it to the desired diameter. The
amount of tube expansion is set by the diameter of the ball. Using water as the driving
force, the pressure quickly drops when the ball clears the tube allowing the ball to exit
the tube at a low velocity for easy capture.
