Round Hole Perforated Drilling Pipe

Pre-Packed well Screen
June 26, 2017
Pipe base 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. For each gauge opening in the screen we select a slightly greater than that of the perforated base pipe.
This will give the pipe base screen optimum flow-capacity at minimum pressure drop across the screen.
The base pipe, casing or tubing, is selected to API specifications by size, grade and weight for each of your required applications.
