What is API RP 13C requirements for shaker screens

Some manufacturers provide screens that are all API rated and tested by third-party agencies to meet API RP 13C requirements. Screens may also be subjected to other
tests including chemical immersion testing in fluids such as diesel, alpha-olefin, calcium chloride, caustic soda and kerosene.

In all cases, one manufacturer’s polyester, powder-coated screens demonstrated environmental exposure resistance when compared to other screens.

The API screen designation is the customary standard for the identification of screen panels in the industry. Before the API RP 13C standard, a huge disparity existed in screen designations, which caused confusion for end users.

shaker screen

Specific to screens, the API designation is the micron opening size and the conductance, which is measured 
by the ease of flow for liquids through the screen. Larger volumes represent a higher volume of handling. Screen manufacturers in compliance with API provide screen labeling that includes the following information:

API designation
Conductance in kilodarcies 
per millimeter
D100 particle size value
Non-blanked open area in square feet

DC Solid control shale shaker screening supplier

Shale shaker screening is the primary means of solids separation. If the shale shaker is not working correctly or if the screens are incorrectly sized or torn, efficiency is drastically reduced.

shaker Screening action depends on the vibrating action to make mud flow through it. Vibration under mud load creates stresses on the screen and if the screens are not properly installed and supported, they will quickly wear or tear.

shaker screens

Shaker Screens are available in square, rectangular and layered design. API has set standards on screen identifications. Screens are labelled with the following: separation potential (216, 250, 284), conductance and area. This notation is necessary because so many variables are possible in screen manufacture – wire size being the most significant.

Weave of wire cloth and mesh count are two interesting design variables. The square and rectangular weaves are the types most often used.

DC Solid control can provide all kinds of shaker screens, please contact us if you have interest with it.

The most important method to remove solid is the vibrating screen

One method of removing solids from drilling mud is to pass the mud over the surface of a vibrating screen. Particles smaller than the openings in the screen pass through the holes of the screen along with the liquid phase of the mud. Particles too large to pass through the screen are thereby separated from the mud for disposal.

Screening Surface. Screening surfaces used in solids control equipment are generally made of woven wire screen cloth, in many different sizes and shapes. The following characteristics of screen cloth are important in solids applications.

screens

Screens may be constructed with one or more LAYERS. NON-LAYERED screens have a single screen cloth mounted in a screen panel. These screens will have openings that are regular in size and shape. LAYERED screens have two or more screen cloths, usually of different mesh, mounted in a screen panel. These screens will have openings that vary greatly in size & shape.

Mesh is defined as the number of openings per linear inch. Mesh, can be measured by starting at the center of one wire and counting the number of openings to a point one inch away.

SIZE OF OPENING is the distance between wires in the shaker screen cloth & is usually measured in fractions of an inch or microns. Screens of the same mesh may have different sized openings depending on the diameter of the wire used to weave the screen cloth.

shaker screen

The smaller the diameter of the wire results in larger shaker screen openings allowing larger particles to pass through the screen. The larger the diameter of the wire, the smaller the particles that will pass through the screen Remember: It is the size of the opening in a screen not the mesh count that determines the size of the particles separated by the screen.

PERCENT OF OPEN AREA: is the amount of the screen surface, which is not blocked by wire. The greater the wire diameter of a given mesh screen, the less open space between the wires. For example; a 4 mesh screen made of thin wire has a greater percent of opening than a 4 mesh screen made of thick wire.

The open area of a non-layered, square or oblong mesh can be calculated and should be available from your screen supplier.

Besides, Hook strip shaker screens have many different type, soft hook strip, metal back (back bounded) hook strip; the metal back hook strip can be flat type or Pyramid (PMD) type. And the hook can be any structure according the design of the shale shaker.

General Rule of shaker screens placement

Pre-tensioned screens are available in different sizes to fit individual systems. Operating conditions should determine screen selection.

Since screen mesh count and screen ratings can significantly impact shaker performance, choosing the correct screen is critical. Each screen directly influences the ability of the shaker to achieve solid/liquid separation and consistent conveyance.

shaker screen

As a general rule, coarser screens are placed on the rear and lower decks, while finer mesh screens are placed near the output. If using a dual deck shaker, finer screens are usually located on the top deck and more coarse screens on the bottom.

Operators should remember that finer screens wear more quickly, especially when subjected to high volumes of solids, such as when top-hole drilling is occurring. Experience will also help guide screen selection regarding flow rate and solids type to maximize solids removal and discharge dryness.

Use common sense of shaker screens

Shale shaker can eliminate solid phase particles, it rely on the screen hole size and shape. Field data shows that, using 12 mesh coarse screen most can remove 10% solid phase in drilling fluid.

In order to more and more fine drilling cutting can be removed, we should use 80-120 mesh fine screen. But it can produce the new questions. The screen hole area of fine screen is less than common screen, then decrease throughput; the fine wire strength is low;
When high viscosity drilling fluid through fine screen, the screen hole is easy to be blocked, even completely paste live.

shaker screen

In order to improve screen service life and resisting blocking capacity, the field is also using the lamination shaker screen, the lower coarse mesh shaker screen has the function of supporting. In addition, between layer and layer have certain space distance double or multiple screen. Usually the upper is used coarse screen, the substory is used fine screen. Upper coarse screen eliminate coarse solid phase, it can decrease the burden for substory.

screens

The shortcoming is; cleaning, maintenance and replace of substory is difficult. Because screen more fine more be blocked, so the amplitude of fine shale shaker is exceeding the common shale shaker. According high amplitude to strong vibrate, it can decrease the congestion extent and prevent screen paste phenomenon.
