TOOL DESCRIPTION 

 

ALIGNING FORCE 

 
WCA4TM 
 

 
Mechanical Fixed Flange and Rotational 
Alignment Tool 
 

 
4.0 T (40kN) from 50 lbf.ft (67.8 Nm) of 
torque 

 
 

4 – FLANGE MISALIGNMENT DETERMINATION PROCEDURE 

 
The tool being used must not be attached to a flanged joint prior to the misalignment procedure being 
carried out. 
 
 
 
 

4.1 LATERAL MISALIGNMENT 

 

1)

 

Loosen and remove every second bolt around the flange, continue with this until misalignment 
occurs. 

 

A flanged 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 of misalignment (point A or B in the examples 
shown below) as shown in section 5.3.
