The high load developed by the multiple bolt tensioning tools, is evenly distributed around the joint causing the gasket to flow into the surface irregularities of the flange giving a much better seal.

A hydraulic bolt tensioning tool provides a quick and easy method for tightening large diameter bolts to high and accurate pre-loads. Unlike conventional methods it does not use torque and does not require any forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches. All of these methods have one common enemy, FRICTION. Overcoming thread friction and friction between the nut and the washer uses up over 80% of the torque energy applied to the nut or bolt, leaving less than 20% of the energy to produce useful tension in the shank of the bolt. Variations in this friction loss, from bolt to bolt causes non uniform tension in bolts that have been tightened to the same torque or impact wrench setting.
A hydraulic bolt tensioner is an annular jack which fits over the bolt and nut to be tightened. The jack pushes against the bolted joint and pulls on the end of the bolt, which needs to be at least one diameter longer to accommodate the bolt tensioning tool. Because the force produced, by the jack, is applied directly to the end of the bolt, a tension equal to the load generated by the jack is developed in the shank of the bolt. With the jack applying the tension, it is possible to turn the nut with zero torque until it is tight. The load applied by the jack is then relaxed and a high percentage, depending on the length of the bolt and its diameter, is retained in the shank of the bolt.
Bolt tensioning tools can be ganged together to enable multiple bolts to be tightened simultaneously, to the same high and accurate pre-load. This is particularly useful when compressing gaskets in pipeline or pressure vessel flanged connections. The high load developed by the multiple bolt tensioning tools, is evenly distributed around the joint causing the gasket to flow into the surface irregularities of the flange giving a much better seal.
Flexible hoses with self sealing quick connect couplings are used to gang the bolt tensioning tools together to form a hydraulic ring main. The ring main and tensioning tools are normally pressurised using an air driven pump working from a compressed air supply.

BOLTIGHT has noted a market need for an M56 or 2-1/4 inch tool with anoutside diameter less than 160 mm diameter and a load capacity of at least 1000 kN.
We have responded to this market need by adding a new Tool No 29 to our 1500 bar range. Details of the tool are given above.

1500 Bar System Hydraulic Bolt Tensioning Tools
Twin Hydraulic Connections
This picture shows the twin hydraulic connection version of the 1500 bar tool.The tool has one quick connect nipple to feed oil in, and one quick connect coupling to feed oil out to the next tool. The quick connectors are self sealing when disconnected.
Twin connections can simplify the ring main arrangement for simultaneous bolt tensioning operations.
The tool has colour coded labels and dust caps to match the pump and hoses. (see DS3 for the BOLTIGHT colour code system).Twin Hydraulic Connection Option
Adaptor Sets
Each tensioning tool can be adapted to suit more than one bolt diameter. Small changes in diameter only require a Puller and a Socket in the adaptor set. The Bridge can suit more than one nut size.
PullerSocket
Adaptor Sets
Where larger variations in bolt diameter are encountered the adaptor set may also include a Bridge.
For example Tool No 23 has two imperial Bridges. One for 1-5/8” and 1-3/4 inch bolts and another for 1-7/8 inch and 2 inch bolts.
Tools may also have different Bridges for metric and imperial sizes.
