The controlling technique of the slotted pipes and the software are chosen according to the parameters of the pipes; When the pipes are slotted, the procedure including: pipe surface treatment before process, cooling and eliminating the heat during the whole slotting as well as removing the iron rust and oxide; after the pipes are slotted, quality inspection is done, unqualified pipes are sent to waste collection station; marking the qualified pipes; material certificate is issued and the finished pipes are delivered.

 

Features of slotted well screen

1.Our slotted pipes use API J55/K55/N80 casing and tubing. With strong overall strength, the slotted pipes are not easy to deform.

4.The slot can be longitudinal and vertical and the section of the slot can be parallel and trapezoid types, which creates wide open area.

5.Easy to operate and to be connected with larger inner diameter.
