Mud Solids Control Equipment

Many clients asked us this question, how to revert API To Micron for Shaker screen mesh，even most of shaker screens manufactures in China do not have this knowledge. Some manufacturers use the API number as mesh directly, this will be incorrect, if clients do not have professional knowledge, they will use the wrong mesh screens and can not get the ideal result.

Here we will introduce how to revert API To Micron for Shaker screen.

API shaker screen

This is a chart to show how to convert mesh to microns, to know how to convert microns( D100 separation), then to know how to convert mesh to API, or API to mesh, pls contact GN solids control.

We can produce replacement shaker screens for Derrick 500, Derrick 48-30, Kem-tron KTL48, Swaco Mongoose, Brandt King Cobra shaker screens.

GN solids control can produce replacement screens for Brandt Cobra shale shaker, both steel frame screen and pyramid screen.

Why people want Pyramid Brandt Cobra shaker screens?

A   Exclusive benefits of pyramid screen technology

1 Increased shaker capacity

2 makes fine separations

Brandt Cobra screen

3 drier drilling cuttings

4 Enhanced permeability

B    Steel frame screen is constructed with two or three stainless steel layers bonded tightly to the steel frame. The frame is made of high-strength square steel tube or flat steel welded to multi- ribbed construction. These layers are coupled with the frame through metal backing plate or bonded straightly as well.

Advantages of steel frame screens

1 Using wedge-shaped fastening technology, to save screen changing time and less shaker spare parts cost

2 High strength frame, multi-ribs and the mesh cloth with moderate tension, from one reliable combination, which can increase screen’s acceptable flow, the intensity and the lifetime.

 If we combine the two type screens together , pyramid screen became the complementary of the original steel frame screen. For example, the total non-blanked screen area is increased by using pyramid technology but it still remain stable steel frame.

 Calculation of total non-blanked area for a panel screen

1 Measure the length and width of a panel opening with a dial or digital calliper to the nearest mm.

GN designed some new models shale shaker in 2011, all of them are BEM shaker with 3 screen panel, the shaker screen dimension is larger than Derrick FLC 500 & 2000 series shaker, even 3 panel screen area is larger than Derrick 4 panel screen area.

The new designed shale shaker is according to API standard of design procedure,GNPS70-3,GNPS85-3 all matched standard oilfield solids control mud tank.

API standard design procedure of shale shaker

1 Shale shakers skids shall be level.

2 Shakers shall be rigged with adequate space, walkways and handrails to permit easy and safe servicing.

3 if the shaker is equipped with a rear tank, the flow line shall enter the rear tank as near the bottom as possible.

4 A means of diverting fluid from the flow line is recommended to permit the disposal of cement, spotting fluids, contaminated fluids, etc, before these fluids reach the shale shaker. The procedure shall not be used to dump the rear tank into the sand trap before trips.

operation procedure of shale shaker

1 The screens shall be inspected every time circulation is interrupted.

2 Use the shaker screens with the smallest openings that do not cause excessive drilling fluid loss.

3 Under normal operating conditions and when using a single-deck shaker with multiple screens, all screens shall have the same API designation.

4 Torn or damaged screens shall be replaced or repaired promptly.

  e.g.GNZS63-3 shale shaker use wedge technology, it is easy to change and install Brandt Cobra shaker screen.

GNZS83-3 shale shaker use tension bolts to install screens.

5 When using shaker screens that need tensioning, tension shall be checked 15 min to 30 min after installation and tourly thereafter.

After operating the solids control system with the working of the drilling, to save cost, lengthen the life of shaker screen is very important, the essential thing is an active screen maintance program.
Screen panel flexing caused by dirty, missing or worn deck rubbers. Clean dirty deck rubbers or replace missing or worn deck rubbers. Always change all deck rubbers in the affected section of the shaker.

OLD WAY TO CLEAN SHAKER SCREEN
Remove any solids that become adhered to the screen cloth. Use a water hose or pressure washer to clean screens. NEVER clean screens with a wire brush. If screens become blinded with near size particles it is best to remove and wash with a pressure washer from the back side. Always clean screens if the shaker will be idle for a long period of time. Mud and cuttings that are allowed to dry on screens will eventually lead to premature failure. Continue reading »

API RP 13C is the latest labeling procedure for shaker screens. Internationally, API RP 13C is ISO 13501.Now the API Screen Numbers are determined by the D100 separation (Microns).

Introduction of API RP 13C

The new procedure API RP 13C is a revision of the previous API RP 13E, which was based on optical measurements of the screen opening using a microscope and computer analysis. Under API RP 13E, screen designations were based on individual manufacturer test methods which produced inconsistent labeling. So it has many different criterion, and when we choose the shaker screen for the shakers, we are easy to get in trouble, even now with the API RP13C, we must convert the old one to the new label, then we can choose the right screen.

How They Test

The API RP 13C test contain two parts: cut point and conductance. It is a current criterion. Used all over the world.The tests describe a screen without predicting its performance.

The cut point test is based on a time-proven testing method used by ASTM to classify particles by size.

The D100 separation is used for assigning screen designations. D100 means that
100 percent of the particles larger than the test screen will be retained, and all finer particles will pass through.

Shaker screen is used for shale shaker, as we all know, MI SWACO is a very professional manufacturer of soldis control equipments, so does the shale shaker. Offshore and land rigs running M-I SWACO* BEM-600,* BEM-650* and MONGOOSE* PT shale shakers,and Brandt^ VSM 300^ brand shakers. Mi-swaco manufacturer all types of shaker screens for these shakers. So does GN Solids Control.
DURAFLO* OEM screens for the M-I SWACO BEM-600, BEM-650 and MONGOOSE PT shale shakers and replacement screens for Brandt VSM300 brand shakers offer higher throughput rates than metal screens as well as longer life, lower weight, and fast, easy repair. And GN Solids Control, as a professional manufacturer of soldis control system, just like Mi-Swaco, Brandt, can supply all kinds of replacement of shaker screens for miswaco derrick and brandt.

There are four different screen meshes miswaco and GN can offer, with the DURAFLO frame as a solid base.

XR MESH for unmatched screen life and exceptional capacity. Largerdiameter 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.
