johnson gravel pack screen

johnson gravel pack screen is manufactured from two components: the base pipe and the slip-on screen.
The base pipe will be perforated with a series of holes drilled to a pre-determined quantity and pattern, to carefully balance flow-capacity at each end for both down-hole handling.
The holes are then debarred and the joint cleaned, inspected and treated to give the base pipe a long shelf life.
Our slip-on screens are manufactured to very exact diameter, length gauge and strength tolerances.
This is done by selecting the required profile wire and support rod, which determine the flow-capacity and strength of the slip-on screen.
