KINGWELL Slip Joint Features & Benefits:
KINGWELL Slip Joint Technical Data:
The slip joint is an expansion and contraction compensating tool, It accommodates any changes in string length caused by temperature and pressure during a downhole test.
The slip joint has two distinct parts: an outer housing and a moving inner mandrel.
A slip joint operates by balancing its volume. As the slip joint stretches and increases its internal volume, a differential piston within the slip joint allows the same volume of fluid into the pipe. The net result is no change in internal volume.
