Experience Top-Quality Equipment with ESI’s Premier Flange Spreaders

Traditional ways of spreading a flange versus the step wedge flange spreader

Assert Your Authority & Take Back Control with Step Wedge Flange Spreaders!

Newton’s First Law states, “An object at rest remains at rest, and an object in motion remains in motion at constant velocity unless acted upon by an unbalanced force.” Similarly, Newton’s Third Law asserts, “For every action, there is an equal and opposite reaction.” These principles highlight the importance of precision in force application.

At ESI, we provide flange spreaders that empower operators to apply force with precision, ensuring controlled and measured force is used for every task, aligning with the core principles of physics for optimal results.

We offer a full line of innovative tools designed for making flange maintenance safer and easier. Among the most popular are their line of Step Wedge Flange Spreaders. They offer both hydraulic and mechanical options.

The Step Wedge’s unique design allows the operator to perform the task in a controlled and predictable manner. Each Spreader, like others has a handle, but unique to their flange spreader, they include high quality soft grip technology to avoid hand fatigue in difficult locations.

Hydraulic options include a hydraulic hand pump with “Sealed Bladder” technology. What this means is that you can hold or secure the pump to any object or apparatus without worrying about leakage or air locks. Twin Kits include dual port hydraulic, which reduces the need for additional operators and guarantees an even spread on each side of the flange.

 

Applications Include:

Hydraulic flange spreaders are versatile tools used across various industries for tasks that require the separation of flange joints.

  • Flange facing: Resurfacing flange faces for maintenance purposes.
  • Pipeline maintenance and construction: For spreading pipe flanges during repair or replacement of gaskets and valves.
  • Pressure vessel servicing: Accessing the internals of pressure vessels for maintenance or modification.
  • Power plant operations: Maintenance and repair of various equipment within power plants.
  • Offshore platforms: Performing maintenance tasks on flanged connections in offshore oil and gas operations.
