Split Sleeve Technology

Slip Sleeve Technology

Hydro Tech Inc. is pleased to offer new split sleeve technology for turbine shaft journals.

The purpose of a shaft sleeve is to restore or modify the proper outside shaft journal diameters. Other typical sleeve installation requires a sleeve designed to be either bolted or welded together.  Welded sleeves require precision machining at a manufacturing facility or onsite, while bolted solutions do not achieve an adequate interference fit.

Hydro Tech’s innovation is a split-sleeve design that is factory-machined to exact dimensions for the required inside shrink fit and final outside diameter.  This unique split sleeve design requires the sleeve be heated for installation. Once cooled, it provides an exact interference fit to the shaft with a polished journal surface, eliminating the requirement for field machining.

Hydro Tech has already deployed this split sleeve solution in the field and will be looking for appropriate projects with our existing and new clients who wish to take advantage of this offering.  The filing of this patent demonstrates Hydro Tech’s leadership in the North American Hydro Electric services market through innovation and applied research.
