SEVERE LOCALIZED PITTING CORROSION & MORE THAN 50% PIPE WALL LOSS
6,000 metres of 8″ crude oil transportation pipeline was severely corroded. The pipeline has been in operation for 30 years and it is to be repaired and rehabilitated to ensure integrity and prolong its service life, under operating pressure of 350 psig.
Wrap Seal PLUS corrosion repair system was used for the pipeline rehabilitation in this project. First, the pipe surface is cleaned and Wrap Seal PLUS resin and activator mixed and applied onto the pipe surface. Next, Wrap Seal PLUS fiberglass repair tapes were applied to reinforce the pipe wall thickness. This pipeline rehabilitation project was completed successfully in 3 months.
