WWS Wire Wrapped Screen for Sand Control, Pipe Base Screen, 4 1/2''
N80
Tiptop manufactures sand control screens for Oil & Gas industry,
which include wire-wrapped screen, precision punched screen,
precise microspore composite screen, wire wrapped & bridge composed
pre-packed screens, etc, and slotted liners. We have the capacity
to design and manufacture as per your specific requirement. Please
contact us to order your WWS pipe.
Wire-wrapped screens retain the gravel in an annular ring between
the screen and the formation. Wire-wrapped screens have
substantially more inflow area than a slotted liner. The screen
consists of an outer jacket that is fabricated on special wrapping
machines that resemble a lathe. The shaped wire is simultaneously
wrapped and welded to longitudinal rods to form a single helical
slot with any desired width. The jacket is subsequently placed over
and welded at each end to a supporting pipe base (containing
drilled holes) to provide structural support.
The typical pipe-base screen fabrication consists of a grade 316L
stainless steel jacket placed over a N-80 pipe base; however, other
metals can be specified as required for site-specific applications.
The inflow area of screens varies from about 6 to 12% (or higher),
depending on the slot opening.
Features:
1. Key-stone shaped slot pattern, self-cleaning, not easy to block
and low risk to plugging.
2. Superior resistant to corrosion, long service life.
3. Optimized design for perforation, all welded structure, high
mechanical strength.
4. Min. 0.05mm slot width, which can satisfy requirement of the
most well completion requirements.
5. Various wire methods are available.
