For over 20 years, Equalizer International has designed and manufactured mechanical and hydraulic flange maintenance tools to service bolted flange joints on pipeline, valves and other fluid processing and transfer equipment.  The full range of innovative tools provide fast, safe, cost effective and simple solutions to flange alignment, flange spreading, flange pulling (closing) and precision lifting.


Quality Engineered Solutions are at the very heart of Equalizer’s tools. They are used around the world, every day, providing operators with time saving solutions to flange maintenance problems. The tools are ideal for offshore, subsea and onshore commissioning, construction, maintenance, shutdown or turnaround projects, within the oil and gas, petrochemicals, nuclear, water, mining and renewable energy sectors.


Safety and PortabilityEqualizer Maxi Kit for SWi Spreading Wedge - Flange Spreaders


With the introduction of the Equalizer flange tools, those tasked with handling flange alignment, spreading and pulling projects can now be confident in using a totally safe solution.


Equalizer tools are portable and have been designed to be easily transported and set up. They are easy to use and have clear safety instructions, overcoming many of the dangers associated with traditional flange working practices.


Traditional Methods vs. Equalizer’s Innovations


Alignment, Lifting and Leveling Tasks

Flange alignment and load leveling is a dangerous and expensive operation because it requires the operator to deploy an unknown amount of force in a controlled and precise manner.  Equalizer’s tools provide the means of achieving this with simplicity and unprecedented safety.




Traditional methods of fixing misalignment and leveling involve:
    High Risk
    Time Consuming
    Labor intensive
   Benefits of using Equalizer’s alignment and lifting tools:


Flange Spreading




Manual tools are imprecise and pose high risk of damage to flanges and injury to personnel.
    High Risk
    Damage to Flange
    Labor intensive
  Equalizer’s flange spreading tools employ wedges and a sealed external hydraulic pump to securely force the flange faces apart under control.

Hydraulic Integral Pump

Sure-Grip Spreaders Use on flange joints with no access gap (zero gap), when contacting the flange faces is a concern and when a spacer, wafer or butterfly valve is positioned between the flanges.
Employs Equalizer’s patented expanding collet technology for safe separation of flange joints that have little or no access gaps with its secure bolt hold locking mechanism.
Collets expand and grip the flange’s bolt holes eliminating the need for a gap between flanges for spreading.
Virtually universal, will spread any ANSI/SAME, DIN, SPO, API or BS flange.
