Pressure Isolation Tool

T.D. Williamson’s SmartPlug isolates pressure in specific sections of pipelines and risers so that repairs or interventions can be carried out safely. Operated by remote control, the tool is certified “safety class high” in accordance with OS-F101 for submarine pipeline systems, the company said. It is certified and type approved by Det Norske Veritas to execute independent double-block isolation to provide a safe environment for divers while working near a pressurized gas pipeline.
