Slotted Pipe
HD precision slotted pipes are manufactured by CNC-controlled slotting machines or laser machines. The base pipe is per API casing or tubing specification with diameters from 1.5 inches to 18 inches. Pipe lengths of any diameter are available. All slotted joints are deburred internally, cleaned, and drift tested according to API standards. Every slot is visually inspected and cleaned of burr material. All threads and couplings are thoroughly cleaned and lubricated. Slotted liners are suitable for gravel-packed completions or stand-alone completion where the grain size is large.
Slotted pipes are a robust and cost-effective solution providing borehole stability and sand control in long horizontal completions and low productivity wells.

Tips
How many holes are needed to achieve a certain open area?
N = 12*3.14*D*C / 100*W*L
N = the number of slots per foot.
D = Outside diameter of the liner (in inches).
C = Open area percentage.
W = selected slot width (in inches).
L = Length of slot (inches).
