Wire-wrapped screens. An even, continuous gap along the whole joint.

A profiled wire wrapped and welded over longitudinal rods on a perforated base liner. The gap between wires is continuous and even, which gives more open area than a slotted liner.

In section. Wire, rods and base liner.

The wire is wrapped over longitudinal rods laid along a perforated base liner.

The gap between two wires is narrowest at the outside and opens inward, so a grain that passes the surface passes the screen.

Drawing. The gap is drawn far wider than true.

Wrapping. The wire is wrapped over the rods and welded where it crosses each one.

Jacket. The jacket is fitted over the perforated base liner and welded at the ends.

Inspection

Each joint. Each joint is checked before it leaves the hall.

Quality system. Our quality management system is certified to ISO 9001 by Fondonorma, a member of IQNet.

Drawing. Wire count and gap are illustrative.

Screen models

  • Superflujo. For a larger open area and more flow.

  • Térmica. Wire, rods and welds chosen for steam injection wells.

  • Preempacada. Two concentric jackets with graded gravel between them, for wells where a gravel pack is not practical.

What to send us

Send it through the enquiry form, by email or on WhatsApp.

  • The outside diameter and the weight or grade.
  • The screen aperture.
  • The joint length and connections.
  • The quantity.
  • The delivery point and date.
  • A drawing, if you have one.

The aperture is chosen from the formation sand, usually by sieve analysis. Mesh sizes are illustrative.

Questions

From the size of the formation sand, usually from a sieve analysis. Send us the analysis or the aperture you need.

A screen gives more open area and an even gap along the whole joint. A slotted liner is cut from the casing or tubing itself. We make both, so we can quote either.

Perforated casing or tubing, supplied by you or sourced by us.
