Emergency Pipeline Repair
20-inch TDW double STOPPLE® in action
After a smart pig in-line inspection identified severe corrosion on a 20-inch high-pressure natural gas pipeline, immediate action was needed. The Virginia utility turned to Daryl Smith, Sr. Application Specialist from Kerr Engineered Sales to set into motion an emergency project. The corroded section had to be replaced in two weeks without interrupting gas service.
Equipment and technical support for the double STOPPLE® train with full bypass was fast tracked. Daryl worked with T.D. Williamson to rapidly secure STOPPLE® isolation equipment, fittings, and completion plugs. Schedules were rearranged so that a TDW Technician could be on site within days.
On site, crews installed fittings and valves on the live pipeline and performed hot taps at multiple sites. The emergency project used 20” double STOPPLE® plugging equipment that isolated each section and controlled the flow of gas.
Complicated Bend
A bend in the pipeline was an added challenge
A temporary bypass maintained gas flow while the damaged pipe and bends were removed and replaced. One section of approximately 30-feet included a bend, complicating the project.
Once the corroded section was replaced, the isolation equipment was removed and the pipeline was safely restored to normal operation.
Risks & Fines Averted
The emergency repair was completed within two weeks, restoring the integrity of the pipeline without interrupting gas service.
Due to highly skilled crews and fast acting support, the risks and costly fines associated with a severely corroded pipeline were averted without interrupting gas service.
