Inspection of Crossovers and Risers

Inspect the outside surface of crossovers and riser pipes or tubing for cracks at welds or rolled sections. Check rolled sections, flange, pressure and thermowell connections for leakage. Hammer-test or ultrasonically gage all crossovers and risers. Inspect the inside surfaces of crossovers or risers where available, for corrosion.
Establish gage measurement reference points as required to follow corrosion. Where corrosion-resistant liners are used, inspect for cracks, leakage, or collapse of the lining material.
