6 Inch Hydrogen Line

The 6” Tee with 4” branch had suffered from external corrosion close to the Tee.

The 20” line had suffered from internal erosion. This resulted in through wall defects on the flange.

The 8” steam header had suffered from internal erosion causing a through wall defect.

The 30” Crude oil line had suﬀered from (CUI) external corrosion.

The 48” Cooling Water line had suffered from external and internal corrosion.

The 4” pilot valve was leaking from its rubber diaphragm

The 4” Condensate line had suffered from coating damage resulting in a localised corrosion area.

The cooling water line had suffered from severe external corrosion.

A hairline crack was identified on a 24″ GRE Seawater line at the flange, resulting in a leak.

The cooling water return line has been repaired using welded patches during a recent shut down.
