The All Welded Wire Wrapped Screen combines high strength and superior corrosion resistance for unsurpassed durability. High quality 304L and 316L stainless steels are the standard materials used in the manufacture of Variperm's screen products.
The stainless steel ribs and wrap wire are sized and spaced for maximum strength at a specified depth. Each individual rib wire is electric resistance welded to the wrap wire at all points of contact. This process develops a strong robust screen with an unobstructed outer surface that allows fluid and particulate to flow freely around and over the screen. The slot size is permanent and accurate. Wire wrapped screen provides a continuous slot that maximizes the available open area.
Pre-packed assemblies use an inner and outer screen jacket in combination with a filter pack to provide an economical method of gravel packing a well. For added strength, a perforated base pipe can be used as a carrier for the screen assembly.
