Description

The Stainless Steel Reverse Rolled  Pretreatment Screen Pipes are made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods. Each intersecting 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.

Continuous slot:

     Stainless Steel Reverse Rolled  Pretreatment Screen Pipes support rods and longitudinal wire makes anopening which significantly increase the available opening area, and allow better access to the water flow.

High open area:

    Stainless Steel Reverse Rolled  Pretreatment Screen Pipes reduce the water level, thus to save energy consumption. Meanwhile, high open area can make the groundwater enter the screen much slower than  other filtration apparatus, which can avoid sandfrom entering screen due to high pressure, hereby lowering pump wear down.

High Strength:

    Stainless Steel Reverse Rolled  Pretreatment Screen Pipes take 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.
