Flange Alignment tools can be used to align or re-align flange joints during pipework construction, commissioning or during routine maintenance.
The tool is attached to the flange joint where misalignment is at its greatest and then simply push and pull the flanges into correct alignment.
Depending on the size of the flange joint and the alignment force anticipated, there are 3 sizes of Equalizer™ flange alignment tools to choose from.

We are discussing here about FA1TM Mechanical Flange Alignment Tool in this Blog-
The Equalizer FA1TM TOOL is an aid of use in normal maintenance and installation procedures to enable the realignment of misaligned flanges within respective working capacities. For example, the tool can be used to assist in the replacement of ring and other types of flange joint. The use of these instructions will promote safe use, and maximise the service life of the tools.
1.The FA1TM is secured to the lower of the two flanges by fully inserting the lift hook into the bolt-hole at the point of greatest misalignment.
2. The drop leg release knob is slackened and the drop leg is adjusted down to the pipe while the tool is held level in the bolt-hole.
3. The drop leg release knob is then tightened until firm.
4. The strap and buckle are attached to the drop leg and around the pipe for added security.
5. The crank handle is then turned clockwise until the driven wedge comes into contact with the circumference of the opposite flange.
procedure being carried out.
LATERAL MISALIGNMENT
1. Loosen and remove every second bolt around the flange, continue with this until misalignment occurs.
A flange joint, once broken down, may spring out of alignment at any point, or in any direction around its circumference. Misalignment may not occur until only a few bolts remain.
2. At this point the direction of any misalignment should become obvious. The alignment tool being used should be attached at the maximum point misalignment (point A or point B in the examples shown below) as shown.
1.Carry out the Flange Misalignment
Determination Procedure
(see section) to determine the points
of maximum misalignment.In this example, the points of maximum misalignment are at the top
and bottom of the joint.
2. Guide the lift hook into the bolt-hole at the point of maximum misalignment.
Adjust the drop leg down onto the pipe by slackening the release knob in an anticlockwise direction. The tool should be held up level within the bolt-hole during adjustment.
NB: The tool must be parallel to pipe during operation.
3. Rotate the crank handle clockwise until
the driven wedge makes contact with
the opposite flange.
4. Thread the strap through the aperture on the base of the drop leg as shown.
5. Feed the open end of the strap through the buckle mechanism as shown.
Close the clasp to secure strap.
6. Now that everything is secured, rotate the handle clockwise to apply pressure to the circumference of the opposite flange & bring the flange joint in
alignment.
7. Once in alignment the bolts may be inserted and tightened. After replacing all of the bolts (apart from the bolt which will go into the bolt-hole in which the FA1TM is located) remove the tool by reversing steps 2-6. Insert the last bolt and tighten.
2. Any missing or damaged items are to be replaced as soon as possible and prior to the tool being used again.
3. Store the FA1TM in a cool, dry place and ensure all machined surfaces are greased.
4. Ensure wedges, pins and legs remain grit free and that parts move freely
2. Using a small flat screwdriver, lever out one circlip and unscrew 6 x 6mm hex screws.
3. Remove cover plate and remove any dirt or corrosion from moving parts.
4. Inspect components for wear and damage, replace if necessary! If there is no damage present, then they can be greased and re-assembled by reversing steps 1-4.
Recommended grease –
Rocol Sapphire Hi-Load or equivalent good quality hi load bearing grease.

HOW THE FA1TM WORKS
2. The drop leg release knob is slackened and the drop leg is adjusted down to the pipe while the tool is held level in the bolt-hole.
3. The drop leg release knob is then tightened until firm.
4. The strap and buckle are attached to the drop leg and around the pipe for added security.
5. The crank handle is then turned clockwise until the driven wedge comes into contact with the circumference of the opposite flange.
FLANGE MISALIGNMENT DETERMINATION PROCEDURE
The tool being used must not be attached to a flanged joint prior to the misalignmentprocedure being carried out.
LATERAL MISALIGNMENT
1. Loosen and remove every second bolt around the flange, continue with this until misalignment occurs.
A flange joint, once broken down, may spring out of alignment at any point, or in any direction around its circumference. Misalignment may not occur until only a few bolts remain.
2. At this point the direction of any misalignment should become obvious. The alignment tool being used should be attached at the maximum point misalignment (point A or point B in the examples shown below) as shown.
INSTALLATION AND OPERATION

Adjust the drop leg down onto the pipe by slackening the release knob in an anticlockwise direction. The tool should be held up level within the bolt-hole during adjustment.

EXAMINATION & STORAGE
1. On return from each job before allocation against subsequent work, the completeness of the Equalizer FA1TM kit must be established and items examined to ensure that they are serviceable.2. Any missing or damaged items are to be replaced as soon as possible and prior to the tool being used again.
3. Store the FA1TM in a cool, dry place and ensure all machined surfaces are greased.
4. Ensure wedges, pins and legs remain grit free and that parts move freely
MAINTENANCE
1. Secure the tool upright on a bench.2. Using a small flat screwdriver, lever out one circlip and unscrew 6 x 6mm hex screws.
3. Remove cover plate and remove any dirt or corrosion from moving parts.
4. Inspect components for wear and damage, replace if necessary! If there is no damage present, then they can be greased and re-assembled by reversing steps 1-4.
