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.
