I.                   basic parameters:

Materials: stainless steel 302,304,316,304 L, 316L sieve wire or low carbon steel galvanization silk.

Outside diameter: 4 inches, 6 inches, 8 inches, 10 inches, 12 inches, etc. (20mm - 1000mm).

Slot: 0.1 mm - 35mm deviation: + 0.05 mm.

Standard length: 50-6000mm End connections: Weld or threaded Sieve silk specification: 2.2x 3.0 mm, 2.3 * 3.0 mm, 3.0 * 4.6 mm, 3.0 * 5.0 mm, etc.

The specification: torre 3.8 mm / 22 root, 380 mm / 32 root, 380 mm / 48 root, 380 mm / 50 root Special specifications on request (such as: inside into liquid, reflexed, etc.).

 II, features:

 1. The section for screening all the trapezoid. Wedge graphics width values dimension a 1.3, 160, 180, 2.0, 2.2, 2.5, 3.0, because screen bar section, so aperture for trapezoid within the small, is extremely advantageous filtering and washing. (against) in liquid

2. Reinforcement bar, bar, circular cross section wedge shape, according to the user's different USES, can perform a variety of collocation with screening bar.

III, the properties of product:

1. Firm structure, high temperature corrosion resistance, mechanical performance is good, long service life, safe and reliable.

 2. Joints can be made into parallel connectors, the common thread joint, taper tooth joints and trapezoidal tooth connector.

 3. Mainly used in oil, gas well, well sand control, mud filtering and other many medium can also be used in water treatment, water softening, oil products the filtration and chemical acid in such organic solution.

 “V”shaped ladder-like stainless/carbon steel screen is a perfect combination of V-shaped wire and V-shaped rod or round rod. The wire is welded onto the rod at each intersection point. Advantage .

1. A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.

 2. A “V”shaped profile wire which avoids clogging and ensures an uninterrupted flow.

3. A uniform and efficient well development due to the continuous slot opening.

 4. Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.

5. Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
