PROJECT DETAILS
Denso SA proposed a tape wrapping and flange protection system for an existing below-ground gas line which was originally commissioned in 1982 and required additional corrosion prevention to prolong life expectancy on this particular section of pipe.
Minimal surface preparation was carried out due to the age of the pipeline, followed by the application of our Denso™ Butyl Tape System and the Denso Buried Flange System which were used for the corrosion prevention on the entire section of pipe.
The proposed systems comply with the gas pipeline standards and have been successfully used on a number of gas pipelines across the country.
