The latest revoultionary design from RenQuip has produced the worlds most powerful spreading wedge.

The VIPER-28 range of flange spreaders incorporate many ground breaking unique features. 

  • 277kN (62272lbf) spreading force per tool
  • Jaw tip depth of only 5mm (0.2”)
  • Jaw width of only 55mm (2.16”)
  • VIPER-28 weighs only 5Kg(11lbs)
  • 16mm (0.63”) Jaw Step
  • Friction reducing jaw bearings
  • Single pin tool assembly / disassembly
  • Simplified design – less parts

These features combine to produce a product that is first in class in every specification. 

The  VIPER-28K is a Hydraulic flange spreading tool kit used to separate flange joints for maintenance, Installation, testing and decommissioning. The kit contains a VIPER-28 spreading wedge tool, stepped blocks, safety blocks, stepped safety block and safety Lanyard but a hydraulic pump and hose will be needed to operate the tool (please see our Pump section), it is packaged in a robust carry case for easy transport and storage. 

A very powerful and portable Hydraulic tool, the VIPER-28 is the correct hydraulic tool for Large and medium sized flange joints but with the benefit of the narrow Jaw tip it can also be used on smaller flanges. 

SKU: VIPER-28K Category:

The VIPER-28 tool is design to enter the gap between flanges and force the flange open removing the requirement for traditional rigging equipment and certified anchor points. 

It is highly recommended that a minimum of two VIPER-28 tools are used when spreading flange joints, this allows the operators to control the opening of the flange joint to maintain a parallel gap – this will ensure the tool maintains a secure grip on the flange and prevent pinching the gasket and potential flange face damage. 

The VIPER-28 is actuated by hydraulic pressure that pushes a piston creating a linear force on the internal wedge – the internal wedge then forces the jaws of the tool apart. 

Using high pressure hydraulics allows the operator to generate very high spreading forces without the requirement for an external power source.  

All RenQuip Spreading Wedge Tools are designed to be used in conjunction with RenQuip Flange Alignment tools. 

The Tool is lightweight and portable making it ideal for use in remote locations. 

If more force is required greater multiples of tools can be used.  

All RenQuip tools are manufactured from the highest quality materials and 100% load tested resulting in highly durable, low maintenance products.
