Why Hydro-Expand?

What is Hydraulic Expansion?

There are four main benefits to hydraulic tube expansion

1) No step-expanding – Any thickness of tubesheet can be expanded in one quick operation.
2) Minimal work hardening of the tube material during expansion means that even difficult-to-roll tube materials such as titanium or duplex stainless can be easily expanded.
3) Less wall reduction and less stress concentration from the expanded to the unexpanded portion of the tube results in longer tube life.
4) Improved quality – each tube expansion is controlled by the system parameters and not influenced by the operator.

Hydraulic expansion is the direct application of high pressure fluid within a tube or sleeve in order to form a tight joint between the tube and the tubesheet or a tight seal between the sleeve and the tube. Specifically, high pressure water is captured inside a tube, within the tubesheet. As pressure increases the tube goes into plastic deformation until it makes contact with the tube hole. Additional pressure stresses the ligament but always within the ligaments elastic range. When pressure is released the result is a tight interfacial fit between the O.D. of the tube and the I.D. of the hole.
