Narrative
On 4/07/2017 oneok ngl pipeline employees replaced a pump at oneok's oakhurst pump station. As product was being introduced to the new pump, a release occurred at the temperature socket where a temperature probe is inserted into the pump body. The release was due to a thermowell not being present in the temperature socket. The previous pump had been manufactured with dry temperature socket that did not require the installation of a thermowell. The newly installed pump, of same model, was delivered with a wet temperature socket that did require the installation of a thermowell. When the release occurred, the pump was immediately isolated, product blown down, and thermowell installed. The pump was then returned to service. Oneok has modified its pump installation procedure to determine the temperature socket design before any product is introduced into the pump body.
