Oilfield Screens
DURAFLO composite screens
With more than 30 years’ experience in solids control and drilling waste management, it was only natural that M-I SWACO would invent the composite-frame shaker screen. The evolution began with the patented HIFLO* screen, which was the first to use a grid made from a composite of high-strength plastic and glass, reinforced with high-tensile-strength steel rods.
Today’s patented DURAFLO* screens are the next evolutionary step, delivering even longer screen life and greater ease in making repairs than either HIFLO or metal frame screens. The DURAFLO screen is available with HC, Ultra-Fine, TBC and XR MESH*, giving operators screening flexibility in addition to an overall-improved product.
Longer screen life: The composite frame design provides smaller more numerous panels, evenly distributing mechanical stresses and containing mesh tears when they occur.
Maintains or reduces current screen weight: The DURAFLO composite screen weighs about the same as the original HIFLO screen and significantly less than metal-frame screens.
Easy to repair: The patented SNAP-LOK* plug-repair system, available on DURAFLO screens for the Brandt VSM 300 shaker, reduces repair time to less than two minutes. Simply remove the screen from the shaker and snap in a factory-made plug. This system eliminates the need for removing the damaged mesh and requires no cutting, gluing or bonding time.
Four different screen meshes
With the DURAFLO frame as a solid base, ADG Global Supply offers four different meshes that let you choose the right mesh for the job without sacrificing long life, throughput capacity or any of the other DURAFLO advantages.
- XR MESH for unmatched screen life and exceptional capacity.
Larger diameter wire gives XR MESH screens the longest life in the industry today. Combining XR MESH screens with the DURAFLO composite frame technology allows for exceptionally high fluid-handling capacity. The high conductance also results in reduced mesh loading in comparison to standard mesh types, further ensuring unmatched screen life.
- Ultra-Fine mesh for sandstone.
The Ultra- Fine (XL) screen has been specifically designed to cope with drilling sandstone formations, which can typically present blinding problems when using standard screen meshes.
- TBC mesh for a better cut.
TBC mesh is designed specifically for applications requiring a well-defined separation efficiency or cut.
- HC. High capacity.
HC (high capacity) mesh is another layered rectangular mesh that M-I SWACO manufactures, although it is not patented. The diameter of the wire used to make HC mesh is smaller than the wire used to make XR MESH, and the mesh is not calendared. Compared to XR MESH, HC mesh has more open area and therefore more capacity, but it has a shorter screen life and lower separation efficiency.
