In this article, we will show you how to use the flange spreader tool. I loved the method, and so will you!

Most online instructions regarding the working of the flange spreader tool lacked clear information but this post contains all of the details for you!

So, let's start.

What is a flange spreader tool?

Flange spreading tools are an important part of the on-site engineer's flange repair toolkit. This industrial equipment comes in a variety of designs and is intended to aid in the separation of pipe flange joints. Pipeline construction, commissioning, normal maintenance, and the replacement of valves or pumps are all examples of typical projects.

Flange Spreader Types

Expanding wedges, expanding collets, and Mini-gap flange spreaders with a set size wedge are three typical varieties. Expanding wedges come from either a hydraulic cylinder or a mechanically driven mechanism. Only mechanically operated mechanisms are used in the expanding collet and mini-gap kinds.

What is a flange spreader tool and how does it work?

A flange spreader tool makes pipe repairs considerably easier and safer. This industrial equipment comes in a variety of designs and is intended to aid in the separation of pipe flange joints. Pipeline building, commissioning, normal maintenance, and valve or pump replacement are all examples of typical projects.

The information presented here is only meant to give you a general idea of how the flange spreader tool is used.

Using the wedge type of flange spreader

  • Before mounting the flange spreader tool, make sure at least two flange bolts are in place and the nuts are loosened enough to allow for flange work. Leaving them in place will assist to prevent existing gaskets from falling below and avoid undesired lateral flange movement during flange widening.
  • Determine where the tools should be positioned around the joint. A minimum of two flange spreaders should be utilized at all times. Lanyards are given to keep these from falling.
  • Measure the flange access gap to determine which flange spreader is required.
  • Place the flange spreader tool in the access gap, fully inserted up to the heel, with the entire width of the specified step.
  • Actuate the flange spreader tool to spread the flanges apart.
  • Safety Blocks can be placed into the flange joint once the joint has been opened to the required distance.
  • Before progressively withdrawing the tool until the flange load has been given on them, make sure the whole width of the chosen Safety Block step is fully inserted.

Using an expanding collet flange spreader

A flange spreader tool with a collet is one option if the flange joint has no access space between the flanges or if you're concerned about harming the flange faces. The spreader is secured using two flange bolt holes in this sort of tool.

  • To determine the collet size needed, measure the bolt holes. It's critical to choose the right collet size. If you use a collet that is too small, the collet holder may pull through the hole. A jammed collet is a possibility with a large collet.
  • The right collet should be inserted into the tools. Collets are considered consumables and must be replaced regularly.
  • The tools should be used in pairs, and two bolts should be loosely fastened in place, just like the wedge kind of spreader.
  • The tool's two pieces are placed into the bolt holes. It's important to make sure that collets are only engaged with one flange. The collets can be tightened after they are properly engaged.
  • The cantilever and actuator are then swung into place and secured in place.
  • A torque wrench is used to tighten the actuator.
  • Safety blocks can be inserted after the flanges have been parted.

Mini Gap Flange spreader with a small gap

  • With a minimum access gap of 2.0mm (0.08′′), the Equalizer product is utilized on smaller, lower pressure flange joints.
  • Select the appropriate configuration for the size and kind of flange joint you're separating.
  • It is strongly suggested that two tools be used on the flange joint, positioned 180 degrees apart, as with previous versions.
  • Only the right flange specification will fit the spreading bars. There are no two spreading bars that will fit into the same stud hole.
  • Align the tool with the appropriate stud hole over the flange junction.
  • Insert the spreader bar into the tool's leg and the flange stud hole.
  • Make sure the spreading bar is properly positioned through the tool's second leg. Make sure the wedge is centered between the flange faces.
  • Each opposing tool should be turned half a turn at a time until the necessary gap is reached. It's important to make sure the force is distributed equally.

Importance of Flange Spreader Tool

Flange Spreader Tool is a common feature on pipes used in a variety of industries, including petrochemical, refining, oil and gas, power plants, wind turbines, and pipelines, to name a few.

As a result, a trustworthy flange spreader tool is a must-have in every industrial shop or field. Even if there are no access holes, you may move any flange with the right pipe flange separation tool and avoid harming it.

A high-quality flange spreader tool allows you to tighten flanged joint pipe connections in a safer, more regulated, and efficient manner. Equalizer offers cutting-edge flange spreader equipment to help you complete your project safely, on time, and within budget.
