The latest revolutionary 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 (62,272 lbf) spreading force per tool
Spreading distance 124 mm (4.9”)
Jaw tip depth of only 5 mm (0.2”)
Jaw width of only 55 mm (2.16”)
VIPER-28 wieghs only 5 Kg(11 lbs)
16 mm (0.63”) jaw step
Friction reducing jaw bearings
S ingle 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-28M is a Hydraulic flange spreading tool kit used to separate flange joints for maintenance, Installation, testing and decommissioning.
The kit contains Two VIPER-28 spreading wedge tools, two sets stepped blocks, two safety blocks, two stepped safety blocks, two safety Lanyards, twin port hydraulic pump and hoses – everything that will be needed to operate the tool safely, 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.
The VIPER-28M hydraulic flange spreader kit is a popular choice for engineers because it comes complete with two tools a pump, hoses and all items required to safely spread a flange joint packaged in a single case.
The PH580T pump included in the kit allows a single operator to control two tools independently or simultaneously to ensure parallel flange spreading.
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 with a hand pump (included in the VIPER-28M kit) – this removes 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 and offshore flange maintenance.
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.
