Wire-wrap screens can be fully customized to meet any specific well application. They feature strong assemblies, are resistant to erosion, and cannot be plugged by fines or produced solids.An exclusive slip-ring design isolates the wire-wrap jacket from mechanical loads applied to the screen assembly; i.e., compression, tension, or torque, while maintaining efficient sand control.The typical screen unit arrangements are 32 ft of jacket on 38 ft of base pipe and 16 ft of jacket on 20 ft of base pipe, but any length of handling area for torque tongues can be ordered. The protective shroud can be perforated or louvered and is designed to accommodate a fiber-optic cable.Wire jacketThe first three digits of these codes designate the width of the wire in thousandths of one inch, and the last three digits designate the height, alsoin thousandths of one inch. The wire is available in either stainless steel material or Alloy or carton steel materialFor special applications, direct wrap (also known as shrink fit) can be made available with the same metal options as the slip-on wrap. In this case, the longitudinal ribs are mounted to the base pipe, and the jacket is wrapped and welded directly over this assembly, providing a very tight shrink fit. This process eliminates the requirement of welding to the base pipe, while creating a base pipe and jacket arrangement that behaves likea single part.
