GE Recommended Tooling Upgrade: Frames 6, 7 and 9 Coupling Bolt Hydraulic Tensioner by Riverhawk

Riverhawk, Webinar, Free, HSIG Tensioner


This presentation will discuss and demonstrate the GE recommended tooling that Riverhawk has designed to replace the old legacy tensioners in the field for GE Frames 6, 7 and 9.  The GE legacy tooling manufactured by Riverhawk is commonly identified with the yellow guard surrounding the tool. The newly designed tooling, known as the Hydraulic Safety Interlock Guard tensioner (HSIG), has a new guard design that is orange to allow very quick identification.

This new tooling has been designed to provide users with a significantly reduced lift weight during use as well as a new safety interlock to secure the tensioner in place during the tensioning process.  This new design reduces the potential for operator error that might cause the tensioner to disengage the stud.  In the unlikely event of such disengagement the new guard design will contain the impact and remain clamped on the flange to prevent operator injury.  This new system is compatible with existing hardware and will be used on all new installations.

This webinar will describe the new HSIG tensioner that was designed to address a few key issues customers were having with the older legacy tooling including:

Leaking Issues

One issue customers were having is that the legacy tensioner would leak. This leaking was a result of over stoking the tensioner.  With the new Riverhawk HSIG tensioners, they have been designed to stop the tensioner from getting damaged when over stroked. No longer can you over stroke the HSIG Tensioner, as it has stops to prevent the over stroke condition.

Tensioner Jumping Issues

The other important feature that the HSIG has is its ability to greatly reduce the likelihood of the tensioner jumping. The old legacy tensioner was all one piece so in some applications it was very difficult to attach it to the flange and hardware. This made it difficult to see and/or feel if you had the puller screw fully engaged into the stud to be tensioned. The new HSIG Tensioner is assembled onto the stud to be tensioned, in pieces (modular design). This allows the puller screw to be installed by itself. This makes it very easy to see as well as feel if the puller screw is fully engaged in the stud.

In this informative webinar delivered by Patrick McCormack specifically for plants with GE Turbines, we will discuss the advancements made to the legacy tooling.
