Derrick Equipment Company revolutionized screening technology in 1994 with the introduction of the patented Pyramid™ (PMD™) screen design. This three-dimensional screen design offers the benefits of traditional flat, multi-layered screens while adding a substantial increase in usable screen area. The result is a screen that allows for an increase in fluid handling capacity. Pyramid screens allow rigs to screen finer earlier in the drilling process, thus significantly reducing total drilling fluid and disposal costs.
- Increased Shaker Capacity
- Enhanced Permeability
- Screen Finer Faster
- Drier Cuttings
Just by switching to Pyramid and Pyramid Plus screens, large cost savings and improvements in shaker performance can be achieved. Derrick screens are designed to maximize solids removal capabilities while significantly reducing costs associated with drilling fluid and disposal. Utilizing Derrick screens will lower the percentage of drilled solids in the mud system. Less dilution will be required, decreasing both total drilling fluid requirements and disposal costs. In addition, cleaner drilling fluid will decrease down hole problems which can adversely affect drilling time. All the benefits of clean drilling fluid lead to one end result: Lower Drilling Cost.
Increased Shaker Capacity – Pyramid and Pyramid Plus screens increase the total amount of usable API non-blanked screen area by 105% and 184% on a Derrick FLC 514 shaker.
Screen Finer Faster – Utilizing Pyramid or Pyramid Plus screens enables rigs to screen 2 to 3 mesh sizes finer than with traditional flat panel screens without sacrificing capacity. This maximizes solids removal capabilities.
Makes Fine Separations – Pyramid and Pyramid Plus screens are capable of making separations as fine as 43 microns.
Fits Existing Shakers – There is no need to modify or replace existing equipment. Pyramid screens fit all Derrick shakers, allowing the most efficient use of existing equipment.
Drier Cuttings – Pyramid screens minimize fluid loss by spreading thinner layers of fluid over a relatively larger screen surface, offering more effective drying results.
Enhanced Permeability – Gravity and vibration forces the solids into the corrugated screen’s troughs, thus allowing more fluid to pass through the top of the screenHookstrip flat screens are the series applied most widely at present. These products can be fit for all kinds of shale shakers that use the hookstrip flat screen. This screen panel is constructed with two or three stainless steel layers bonded to a steel support plank. Accessary rubber plugs may be inserted to the rips or tears of the screen. By doing this, we can cut down time and the production cost. We can supply hookstrip flat screens with mesh sizes ranging from 12 to 275.
