Equalizer Flange Spreading Tools by Enerpac

Following the successful acquisition of Equalizer International, we are pleased to show some of the Equalizer Flange Spreading Tools in action. Here you can see an Enerpac Collet Type of Flange Spreader in action.

When the flange joint has no access gap between the flanges, or if you’re concerned about damaging the flange faces, a flange spreading tool using a collet is one solution. This type of tool uses two flange bolt holes for securing the spreader.

• Measure bolt holes to determine collet size required. Selecting the correct collet size is important. Using an under size collet risks the collet holder pulling through the hole. An oversize collet has the potential to become jammed.
• Insert the correct collet into the tools. It’s worth noting that collets are classed as consumables and need regular replacement.
• As with the wedge type of spreader, the tools should be used in pairs and two bolts fixed loosely in place.
• Two halves of the tool, are inserted into the bolt holes. Care should be taken to ensure that collets are engaged with just one flange. When correctly engaged the collets can be tightened.
• Next, the cantilever and actuator are swung and locked into position.
• The actuator is tensioned using a torque wrench.
• When flanges are separated the Safety blocks can be inserted.
