SPECIFICATION of Rod Based Continuous Slot Water Well Screen
1.Layer:Two
2.Minimum slot:0.1mm
3.Standard length:1-6meters
4.Another name:gravel pack screen pipe
5.Screen jacket: Johnson screen
6.Screen Packing tower is equipped with high -intensity shaker to ensure filter media is tightly packed for optimal sand control
We design to allow slurry to bypass sections that have bridged prematurely or become obstructed during gravel-pack operations.
With multiple apertures located along the packing tubes in each screen, flow is redirected through the shunt tube system and the shunted screens more uniformly distribute the gravel or the slurry across the wellbore.
Enhanced Low Profile and Premium Low Profile Prepacked Screens — These screens can be used in gravel-packed and non-gravel packed wells.
They incorporate a strong inner wire wrap layer made from round wire and a keystone-shaped outer wire wrap layer.
Prepacked Screens — When gravel packing is not feasible, prepacked screens provide built-in sand control. They incorporate a keystone-shaped wire for the inner and outer wire wraps.
ADVANTAGE
1. collapse strength equal to pipe;
2. double the tensile strength of standard rod based screen;
3. a bioresistant, hydraulically superior (to silica sand) pack;
4. a greater percentage of open area(for deep applications) than that of a conventional screen, due to the dual support construction

Advantage of perforated casing pipe:
Available in J55 or N80.
J55 and N80 have high strength and less potentiality of deformation.
Punched hoses are smooth and clear without burrs.
Easy installation.
Overall preservative treatment creates a dense protective layer over the surface of the pipe and improves corrosive resistance.
Six types of punched hoses are available for specific application.
Two types of hoses distribution are manufactured.
Rod Based Continuous Slot Water Well Screen will be deep water wells.
