11.2.1

Prior to commencing the final cold alignment, the suction and discharge piping shall be disconnected and piping alignment such as off center, clearance, and parallelism between the piping and connection flanges of the equipment nozzles shall be checked by visual inspection.

11.2.2 When any misalignment is found in the piping during the above inspection, the information shall be given to the CONTRACTOR engineer.

11.2.3

After the piping alignment check is completed and/or misalignment of piping is corrected, the suction and discharge piping shall be connected to the equipment nozzles and the final cold alignment of the equipment shall be checked with a dial gauge.

11.2.4

Any offset on the alignment of the equipment found as a result of the piping connections shall be corrected as follows :

1) Offset values of 0.2mm or less shall be adjusted by inserting or removing shims under the lug or saddle or the driver and/or speed exchangers without correcting and piping alignment.

2) Offset values exceeding 0.2mm shall be reduced by correcting the suction and/or discharge piping by burning or re-adjusting the pipe support, and, if necessary, the suction and/or discharge piping shall be disconnected and be welded again to correct alignment of the equipment and this welding joint shall be done NDE and hydraulic testing.
