HDD installations

World Pipelines magazine published an article discussing the use of composite coating technology to provide improved coating protection during HDD pipe installations.

According to the World Corrosion Organization, USD 2.5T is lost to corrosion each year.

As a result, the pipeline industry has adopted an effective asset integrity management solution to protect its infrastructure in challenging environments. Introducing Scar-Guard®, a composite coating protection technology that prevents coating damage during horizontal directional drilling (HDD) installation.

The article highlights the challenges of HDD installations that are occurring in a broad range of applications. For instance, HDD crossings are being undertaken in challenging geotechnical environments and in environmentally sensitive areas with steel pipe up to 48 in.

Additionally, the article outlines the importance of experimenting and testing methods applied by Shawcor and CSNRI to prove the performance of composite technology being used for pipeline integrity repairs for 20+ years. Such technology provides mechanical protection of pipeline coatings installed via trenchless methods.
