Take the hassle out of gasket and valve swap-outs by using the proper flange spreader. When used in conjunction, you can have up to 50,000 lbs of force spreading your flange apart by the simple actuation of a pump. No longer deal with getting banana wedges stuck inside flanges or spending hours, if not days trying to get a flange in a vault to move.
We offer a wide range of RENQUIP, made in Scotland, self-integrated flange spreaders along with individual sets and dual sets that come with hose and pump.
There are two main types of flange spreaders available:
Wedge Spreaders: The most common style, these feature wedge-shaped noses that insert into gaps in the flange to push the sides apart. Wedge spreaders require existing space between flanges for the wedges to enter.
No-Gap Spreaders: For tightly sealed flanges, no-gap spreaders utilize collets that grab onto the bolt holes to provide enough force to initially separate the flanges. These are specially designed for each flange size.
Within these types there exist models with ranges of force capacity, size fits, and portability:
Flange spreaders provide major advantages over manual flange spreading methods:
Safety: Applying thousands of pounds of force allows flanges to be separated without unsafe use of hammers, wedges, and brute manual force.
Speed: Simple pumping action generates enough power to spread flanges wide in minutes, avoiding hours of laborous and ineffective manual wedging.
Effortless: Once positioned, the hydraulic pump does all the work, taking the strain and difficulty out of flange maintenance.
Precise Control: Spreading force can be carefully regulated to create the exact size gap necessary.
Versatile: Flange spreaders handle valve swap-outs, gasket replacements, tight spots, and more.
When selecting a flange spreader, consider these key factors:

A flange spreader is a device that typically uses a wedge-style nose to allow separation between two flanges. These can be manually or hydraulicly driven. Manual spreaders rely solely on human power and effort to hammer wedges between flanges and spread them. This generates minimal, inconsistent forces. Hydraulic spreaders use fluid pressure to power large integrated pumps and cylinders that can apply precisely controlled spreading forces up to 50,000 lbs
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 in between 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 & tedious task of hammer wedges into flanges to gain enough spread to allow for gasket swap outs. Flange spreaders allow for a hassle-free work environment 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 common 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.
