This Vee Shaped Wedge Wire Screen is composed of rod strips and V shaped wires through manufacturing on specialized welding machine. The rib strips and V shaped wires will be welded by resistance welding, has enough welding strength, equally slot gap, high corrosion resistance, large filter area, good permeability, simple structure.

The Continuous slot screens are made of Vee Shape wire or wedge shape wire around an internal array of longitudinal support rods. Each joint point of these wire is fusion welded, the V or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening. Therefore the screen allows water or oil to enter the well freely in ample quantities while keeps the majority of sand and gravel out of the well at the same time.

• Non clogging: "V" shaped profile wire, avoids clogging, is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and do not wedge in the screen's inwardly enlarging slot.
• Large open area: This allows more water to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.
• High Strength: It takes stainless steel as main raw material, then is welded at high temperature, which guarantee high strength to bear big water pressure, hereby it has long life span.
