Shaker screen layers means the layer overlap design and the detail of screen cloth we use. What is difference among mesh configurations? What is the detail?

Shaker screen layers

Different screen manufacturer will design and configure screen panel with different mesh and layers. Some screens are made with 3 layers screen cloth, some are 2, but some will be 4. Also based on mesh size or the API size we need, there will be different configuration

Most popular ones are 2-3 layers screen. Kindly suggest make shaker screen as 3 layers begin from API 80. That means, API 80, API 100, until to API 325 are all 3 layers. Usually, we'll set the coarse screen sized 14-18 mesh as the first layer, and the finest one is top layer contact drilling fluids.

The screen layers don't mean only filtration but also provide support function for each screen layer.

Different combination on screen mesh and layers

There are different combination on screen cloth for shaker screen. For example, we can use all 3 layers screen with square hole also can use screen cloth with rectangular hole. The bottom support wire mesh can be 12 mesh, 14 mesh, or 18, 20 mesh. The wire diameter can be 0.2mm, 0.3mm, and so on.

Above configuration difference lead different cut point or separation size. So we may understand, why many suppliers provide same mesh screen but they are different API size. Some 80 mesh are API 60, but some are API 80. Also, we find same manufacturer provides API 80 with different shaker screen layers configuration. Then there are HP A 80, DX A80, or RHD and so on

Aipu shaker screen and layers

Aipu is professional manufacturer of shaker screen panels. We are proud to say we've got API RP13C compliant test report in 2014. Now, our shaker screens are 2 or 3 layers per different API size. Coarser than API 80 are 2 layers, finer than that are 3 layers.

If some clients request lower price screen, we'll provide 2 layers configuration. No matter framed screen or hook strip screen the configuration are similar.

There is another special type shaker screen, the unbonded screen. It is only one layer with very strong and thick wire mesh cloth.

If you need shaker screen or you are interested in shaker screen layers information please contact Aipu freely.

Shaker screen layers and mesh size of each screen cloth is important issue affecting screen API size. Different manufacturer will configure shaker screens with different mesh on certain layers

Shaker screen layers

Shale shaker screen layer and mesh size are interrelated. Usually, shaker screen sized coarse than API 70 there are 2 layers. If it is only API20 we just need one layer will be ok

Generally speaking, shaker screens are 2 or 3 layered. Some people call the bottom layer as first layer but some people will call it the last layer. Different layer will be with different mesh size to achieve certain API size of shaker screen

Of course, according to different shaker screen size the screen cloth can be S.S304~316L. As per different users' demand we can do the adjustment accordingly

Screen mesh size

Screen mesh size is different with wire mesh size. Since the shaker screen is combined with 2 or 3 layers wire mesh. We'll test its mesh size according to industrial standard.

Or some manufacture will test the shaker screen according to API RP13C code. This will do clients much favor on selecting correct standard mesh size shaker screen. How could we configure shaker screen mesh as certain API size? For example, we select 18 mesh screen cloth with 0.3mm wire as bottom layer, and 70 mesh screen cloth with 0.07mm wire as intermediate layer, while, 100mesh screen cloth with o.06mm wire as top layer. This configuration may be API 80, also perhaps be API 70. Another combination is 18mesh x 0.23mm, 70x120mesh x0.053mm, 180mesh x0.03mm, this may be API 140.

So, we found the screen layer, mesh size and the diameter are interrelated.

Different  API size of shaker screen

We all know different manufacture will contribute screens under different combination. So may be screens marked with same mesh size they have different API size

For example, NOV Brandt marked screen as 6BHX84-AT and it is API 70. Derrick equipment marked screen as DF145 and it is API 100. We can't identify shaker screen simply as per description without API number.

Selecting different API size screen is professional issue during well drilling. As different drilling step will request different screen for certain filtration result
