2 x 10 Inch Cooling Water Lines

The 2 x 10” lines had suffered from external corrosion

The 24” line buried 10 metres below the ground, had suffered from external corrosion which led to a through wall defect.

The 3 x 24” lines had suffered from excessive external corrosion at the bottom of the lines which are exiting the concrete floor.

The heat exchanger was subjected to thermal cycling that caused a crack to appear at the edge of the expansion joint

The 20” line had suffered from CUI external corrosion on the pipe coming off the vessel.

The 18” Cooling Water line had suffered from severe external corrosion.

8” and 10” nozzles had suffered from internal erosion.

A flange joint connection on a 6” steam line had failed due to possible gasket or flange face issues

The 2” line had suffered from external corrosion.

The 24” line had suffered from severe internal erosion resulting in a through-wall slot defect at a lap joint flange.
