Narrative
October 27th, 2019, a third party notified oneok's pipeline control after observing vapors originating from a pipeline mainline valve location. Oneok field personnel arrived on site and found the leak originating from the top seal of the check valve. Oneok personnel were able to tighten the associated bolts and stop leak. Oneok intends to remove the failed check valve prior to the end of 2019. Oneok will then disassemble the valve in order to determine the cause of the release. Updated 2/6/2020 - paula gates rippe check valve was removed on dec. 27th, 2019. Oneok maintenance technicians disassembled the valve and performed an inspection to all the components. There are no visible defects or damage to the face of either the body or cap. The o-ring groove appeared to be clean and free of damage as well. Damage is evident on the o-ring at the point of the release. Erosion of the o-ring is visible at the point of the release. The entire circumference of o-ring also shows a crease, indicating the o-ring was possibly pinched during installation, which may have contributed to the failure. Corrected apparent cause in part g to improper installation.
