PIPEVAC® provides the answer to elimination and monitoring of corrosion, including corrosion under insulation (CUI), on pipelines by creating and holding a permanent vacuum around the pipe circumference. PIPEVAC® aims to provide an inspection and maintenance free corrosion prevention system, protecting from atmospheric corrosion as well as corrosion under insulation (CUI), with complete 24/7 vacuum monitoring of the pipeline. PIPEVAC® alerts the operator when a breach to the vacuum occurs (internally or externally), this provides the opportunity for real cost savings on external inspection, removal and re-installation of insulation, coatings and pipeline repair.
