SW15TE Flange Spreader – Hydraulic Flange Spreader

Equalizer flange spreaders feature an integrated wedge spreading design that poduces a smooth, parallel wedge movement that creates a force perpendicular to the flanges faces being separated. This design eliminates flange damage and spreading wedge failure.

The SW15TEMAXI Kit hydraulic flange spreader kit includes 2 SW15TE wedge heads giving it a spreading capacity of up to 30 ton.  The kit includes a dual port pump capable of operating both wedge heads simultaneously or each wedge individually.  The SW15TE features an interlocking spreading wedge design with user safety in mind. This design produces a smooth, parallel, wedge movement creating a force perpendicular to the flange faces being separated which eliminates unsafe working conditions, flange damage and spreading wedge failure.

The maximum spreading capacity is 3.3 inches (83.82 mm) with both stepped blocks attached to the wedge head as shown below.


  • The unique interlocking wedge design features no first step bending or risk of slipping out of the flange joint
  • This unique design requires a very small access gap of only .24 in. (6 mm) and is capable of producing a gap of up to 3.3″ when using both step blocks.
  • A total of 15.5 tons of force is available at every step including the first step. Two hydraulic flange spreaders can create 30 tons of spreading force.
  • Few moving parts means durability and minimal tool maintenance.  Any maintenance is simple and easy to perform on this flange spreader.
  • A special coating is applied to reduce slippage, further increasing worker safety.
  • No forces are created that would propel the spreading wedge from the flange like a typical hammered wedge. see IL. 2
  • A solid sliding wedge between the flange speaker jaws eliminates jaw breakage and the potential of flanges flaming together causing worker harm or equipment damage.

This drawing illustrates how forces are applied with the Equalizer spreading wedge. The downward force from the wedge is transmitted in a perpendicular motion to the flange faces. This makes the spreader safe and easy to use.



This drawing illustrates how forces are applied with a standard wedge. The downward force from the wedge is transmitted in a angular motion to the flange faces. This produces a reverse force that try to propel the wedge back out of the flange creating an unsafe environment . This type of wedge will also cause damage to flange face.






A problem may occur when using a SW15TE Flange Spreader on a flange with a larger gap, for example when removing a blind, valve, or large gasket.  The wedge may protrude far enough to hit the blind, gasket, or other object as illustrated below.

The problem is easily solve by using the step blocks as illustrated below

Customers buy flange spreading tools from us that are easy to use and get the job done safely, timely, with improved productivity.

The SW15TE Hydraulic Flange Spreader is a small, unique, durable tool and is an excellent choice for use on most flanges with an access gap of 0.24 inches (6.096 mm).
