Precise Punched-Slot Screen (PPS)

Precise punched slotted screen is a new product which is composed of central tube, precise punched slotted screen jacket and stainless steel ring. It has characteristics such as exquisite controlled hole, high percetnaged of open area, strong integral strength, resistant to deformation to corrosion and high reliability etc. 

PPS Screen mainly consists of perforated base pipe, stainless steel filtration jacket with punched slot, and backup ring. The base pipe is of API casing or API tubing with many drilled holes. The filtration jacket with punched slot is made of high quality stainless steel, and the spatial slot in high dense array over it is achieved by digital control precise punching. In the end, the filtration jacket with punched slot is welded onto the perforated base pipe through backup ring. In application, the formation sand can not easily enter the filtration jacket while the formation fluid can easily flow into screen through space between punched slots. So sand control is achieved.If needed, an extra outer protective shroud can be added outside the filtration jacket so to strengthen protection for the filtration jacket.
