National Oilwell Varco supports the API RP 13C screen labeling practice and has implemented this labeling on the most popular screens, including the RHD, XF, PXL and TBC series.
|
The new recommended screen labeling practice provides the following API RP 13C information:
- API Designation
- Conductance in kD/mm
- D100 Value
- Non-Blanked Open Area in Square Feet

Engineers test and develop screen products in the NOV Analytical Laboratory. This laboratory preforms many different functions, such as:
- Failure Analysis
This analysis allows NOV to better define the root cause of failure. The identification of root cause provides the direction to modify the design for improvement in actual performance, as well as increased durability.
- Fluids Management
The Analytical Laboratory also supports NOV fullscale pilot plant testing. Constant observation and monitoring of calibrated test fluids, which have solids representing each API sieve class, allows NOV to maintain consistency and repeatability in screen testing. This base mud, along with particles of a known size, is used to evaluate the performance of new and existing screens.
- API RP 13C Testing
Dry sieve testing procedures, as well as conductance testing, are considered great tools to apply specific potential values to screens in order to aid in further design advancements.
- QA/QC of Screen Materials
Periodic sampling and analysis of screen cloths ensures consistent quality. Typical analyses include chemical composition, tensile strength, percent elongation, ductility, wire count and wire size.
NOV manufactures screens for the Brandt® brand of shale shakers which includes the Cobra®, VSM® and LCM Series shakers. Replacement screens are also manufactured for competitor equipment. Replacement screens for competitor shale shakers combine proven mesh combinations with an innovative, diamond-patterned plate to improve separation efficiency of the shaker, while extending screen life. These NOV replacement screens are engineered to meet the exact design specifications of the competitor’s shale shaker and can be installed directly on the unit using the stock wedges. Replacement screens are available in a variety of mesh combinations to best suit the needs of the drilling application.

EXTENDING SEPARATION EFFICIENCY AND SCREEN LIFE WITH INNOVATIVE DESIGN AND HIGH PERFORMANCE
Brandt® Premium X-tended Life (PXL) series shale shaker screens effectively and efficiently separate detrimental drilled solids from drilling fluid. These screens have been designed using completely new engineering methodologies, resulting in screens that make cleaner cuts (at comparable API numbers) than the previous sandwich screen designs of the last three decades. Additionally, their innovative design provides a significant increase in screen life as well. Premium X-tended Life screens are specifically-designed for the Brandt VSM 300 shale shaker and are compliant with API RP 13C, Third Edition, December 2004 (ISO 13501 First Edition 2005-12-01).
Brandt Premium X-tended Life (PXL) screens are a product of a new engineering methodology: computer-modeled screen design. PXL screens provide a more stable screen cloth throughout the service life of the screen, which results in improved solids removal. Additionally, Premium X-tended Life (PXL) screens provide users with:
- A reduction in low gravity solids (LGS) and sand content
- Increased screen life
From flowline to disposal, NOV has the solutions to your separtation and waste management needs. Brandt is a subsidiary of National Oilwell Varco, the industry's technological leader.

VNM Series Screens
|
|
INTRODUCING THE NEW STANDARD IN SCREENING PERFORMANCE
The VNM series shale shaker screens utilize an advanced frame design and unique mesh combinations to effectively and efficiently separate detrimental drilled solids from drilling fluid. VNM series screens are designed to fit all Cobra® and LCM series shale shakers.
Specification:
|
Rectangular Heavy Duty (RHD) Screens
|
|
ENHANCING SCREEN TECHNOLOGY WITH EVOLUNTIONARY DESIGN
The Brandt® Rectangular Heavy Duty (RHD) line of screens utilizes two layers of heavy duty rectangular mesh and one layer of coarse mesh to produce a durable and effective screening media. This combination of screen media provides users with enhanced liquid conductance, which allows for a higher throughput of fluids. NOV Brandt RHD series screens also reduce the incidence of plugging and blinding in situations of troublesome sand formations or when using lost circulation material (LCM).
LCM is prone to work its way between the fine screen layers of most double- and triple-layered screens. In severe instances, it can swell and burst fine-mesh screen cloth. The NOV Brandt RHD series screen line was developed as a solution for difficult-to-screen materials such as LCM.
In addition to solving the issues associated with LCM and other troublesome solids and materials, Brandt RHD screens produce less resistance to flow. The proprietary, layered screen technology permits improved fluid conductance, while maintaining consistently sharp separations. RHD series screens are available for the Brandt Cobra, LCM and VSM series shale shakers, as well as select competitors’ models.
