Flange Spreaders

A flange spreader is a device that typically uses a wedge-style nose to allow seperation between two flanges. These can be manually or hydraulicly driven.

There are a variety of flange spreaders on the market. First, all flange spreaders operate at a different capacity, so make sure the model you selected has enough power for your application. The most commonly used spreaders require about 1/8″ or 1/4″ gap in order for the teeth of the spreader to be able to fit. When there is no gap inbetween flanges, one would then look to use a “no-gap” flange spreader. This uses a system of collets and grabs the bolt hole of the flange to pull the flanges apart.

Flange spreaders make the previous dangerous & tedios task of hammer wedges into flanges to gain enough spread to allow for gasket swap outs. Flange spreaders allow for a hassle-free work enviroment as you are able to apply a high might of force between the flanges with minimal effort.

Wedge style flange spreaders are the best option for everyday flange use, these are the most commmon and diverse option. When using a “no gap” spreader, these are specific to every flange so therefore have a lot more moving parts to make sure the job can be accomplished properly.
