precise punched slotted screen

precise punched slotted screen Specifications

Perforated seam is welded in straight line; with unique spiral distribution formed by spiral welding
and greater filter strength. When squeezed in some parts from external, under outside pressure,
the forced part will have reduced or closed gap and ensures the reliability of sand control. Made
with sophisticated technology, stainless steel filter glove has openings in the side with reduced
direct corrosion to the perforated welded sand pipe. Seam gap in the processing ranges between
20 mm-0.7mm. The uniform opening ensures the processing difference is within the error scope
allowed - 0.015 mm, also ensures the accuracy of its filter requirements. Using high precision
perforating technology, the effective slotting length is the three to five times of common cut seam
tube and two to three times of common perforated seam tubes.

uses 

1. Bridge Slot Screen is used throughout the world for water, oil, and gas wells, and for environmental
well completions. It is the dominant screen type used in the water well industry.

2.This type of screen made up of rods and warp.the rod can be round wire,triangular wire and trapezoid wire.

3.The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.

4.The warp is triangular wire(v-shape wire).The water well screens have astructure and high open area;as
well as accurate slot dimension. 

5.Water well screen have heat -resising,anti-corrosive,good machine capability,last long ,satefy and reliability
and so on.
