Steel Casing and Screen Pipes
Wire wrapped screens
Wire wrapped screens made in Nordhausen offer the combination of highest quality, short delivery schedules and competitive prices.
High yield wire wrapped screens
Our wire wrapped screens are highly permeable and have excellent hydraulic properties. Advantages comprise:
Up to 45% or more free open entry area
Installation possible to depths of 2000 m
Smaller diameters can be drilled as gravel packing is not necessarily required
The slogs can’t be clogged due to wedgeshaped surface wires
A wire wrapped screen consists of a wedge-shaped surface wire that has been wrapped and welded to a number of perpendicular support rods that define the inner diameter.
This type of screen has originally been developed in order to install wells in fine, uniform sands.
Such wells are generally constructed in high-yielding in aquifers of low thickness and in shallow depths, but with high yield perspectives.
Nowadays, wire-wrapped screens are highly effective in any formation and application due to the fact that slot widths of less than 0.2 mm can be realised. At the same time, the large open area ensures that friction as well as entrance losses are kept to a minimum.
Depending on local requirements, a wire wrapped screen can be produced in a number of material grades, starting with simple stainless steel right up to highly corrosion-resistant alloys.
