We investigated the cause of leaking/failure in a 2″ diameter floating ball valve in a midstream pipeline. Graphite packing deformation appeared consistent with loads that would be generated from volumetric expansion due to water freezing inside the valve.

 We perform design, analysis and troubleshooting services for clients in industries including energy, mining and oil/gas.
