摘要
A wellhead isolation tool nipple seal testing apparatus includes an upper seal, upper nipple, and a lower seal and a lower nipple, the lower nipple being attached to the upper nipple. Test pressure forced between the upper and lower seals may be used to test the upper nipple up to well servicing pressures. The lower nipple may seal the well bore by being closed, or by the use of a mandrel carrying a seal on its lower end or with a burst disk.
