The filter mesh for wells from a corrosion-proof grid.

Our company produces a mesh filter for wells made of stainless mesh of galloon weaving.
Constantly in stock, and we also produce to order both on our casing pipe and on yours. We carry out delivery in the Kyiv region, send by postal services: «Nova Poshta», «Delivery».

The stainless mesh filter for water wells is used to filter water passing through the stainless filter from the aquifer to the consumer. It protects against sand, clay and other particles from entering the well. The stainless mesh filter is made on the basis of a casing pipe, which is perforated in a certain way in advance and a stainless steel galloon weave filter mesh is attached on top of it. The mesh filter for wells can have a different diameter, length, depending on the design requirements of the well.

When producing filters for water wells, we use:

Grid stainless P 56, stainless grid P-72.

When ordering a downhole filter, at the beginning it is necessary to decide which stainless mesh to use P 56 or P 72? The higher the number, the higher the density of the stainless filter mesh. On the one hand, when using a dense mesh, pollen (very fine sand) from the aquifer will not pass through it, and on the other hand, the higher the density of the mesh, the less throughput the stainless filter for the well has, which affects the decrease in the well flow rate.
If you do not know exactly the properties of the aquifer in which you plan to drill a well, and there is a risk that it may contain very fine sand, then there are several recommendations for this situation:
1. Drill a well with a much larger diameter, install a filter column with a mesh P 56 and sprinkle the stainless filter well with washed quartz sand 2-5 mm. The sand will provide protection from fine sand and the maximum flow rate of the well will be maintained, in this case there is still a risk that the well may become sandy.
2. Also drill with a large diameter, sprinkle with sand a stainless mesh filter as written in paragraph 1, but put an additional stainless filter for the well. This will ensure a good flow rate of the well, provided that there is water in the aquifer.

Which option to choose is up to the drilling engineer to decide.

What influences the service life of a filter for wells and the well as a whole?

The water contains dissolved salts, iron oxides, etc., which, over time, clog the filter cells, which leads to a decrease in the well flow rate. The stainless steel mesh filter cannot be pulled out of the well in order to carry out service work to clean it or change it to another stainless steel filter; it is installed for the entire life of the well. To increase the flow rate, the life of the well, it is necessary to set the number of filters with a «margin» and, after installing the casing string, fill the filter area with large, washed quartz sand with a diameter of 2-6 mm.

Also, the life of the downhole filter and the well as a whole is affected by improperly selected and installed pumping equipment.
