Low-carbon steel filter mesh P68 is much cheaper than stainless steel, but is subject to corrosion, therefore it is used in cases where contact with an aggressive environment is excluded, such as:
- oil filtration,
- screening of dry powder materials,
- structural elements,
- breathable inserts in the lining of machines and mechanisms.
The low-carbon filter mesh is less expensive than stainless, has very high strength and filtration capacity. Black filter mesh does not have as high corrosion resistance as the stainless steel option, but it has high heat resistance and wear resistance, which makes it an extremely popular material in plastic recycling, screening and separating fine particles.
Woven filter mesh GOST 3187-76 galloon weaving is used for liquid and gas filtration, drying and screening of polymer and other crumbs. It works well under pressure and in a vacuum environment, it is installed in wells and extruders.
Woven filter mesh GOST 3187-76 stainless linen and twill weave is produced.
Plain weave - warp wires (at some distance from each other) are intertwined through one with weft wires, which are located close to each other. Designations: P24, P36, P40, P48, P52, P56, P76, P100, P120, P200.
Twill weaving - the warp wires are also located at a distance from each other, but are already intertwined through two wires with weft wires located close to each other. Designations: C56, C72, C80, C100, C120, C160, C200.
Differences in the type of weaving
Mesh is produced in two types of woven weave: twill and linen. In the first case, two weft wires grab one warp wire. Plain weave - standard for woven hardware: one warp wire intersects with weft wire.
What are metal mesh filters made of?
Steel wire is a versatile material for making mesh filters. However, for use in specific conditions, filters are made of non-ferrous metal alloys: brass, copper, bronze.
Mesh sizes
The filter wire thickness is 0.02–0.7 mm. If other types of metal meshes are also distinguished by the size of the cells, then in the filter meshes the wires fit so tightly to each other that the holes are not visible even through the light - they have microcells. Therefore, grids are called zero or galloon.
Filter mesh is a kind of woven mesh with mesh when their clear size is zero. They are also called zero or galloon nets. This type of mesh is used in the petrochemical, pharmaceutical and other industries. The key characteristics of this type of mesh are the type of weaving and the nominal fineness of the filtration.
The filter mesh has several types of weaving: galloon - with small and complex cells, has linen and twill types of weaving. With linen weaving, the longitudinal (warp wire) and transverse wires (weft) are intertwined through one, with twill - through two. A standard mesh with a square cell shape is also used, and a keeper mesh with multilayer weaving.
Areas of application of the filter mesh:
As a filter element and pre-treatment of substances from wells;
For drying materials;
To remove excess water from the soil - in agriculture;
In ventilation and air conditioning systems of food production, business centers, warehouse and office premises, industrial enterprises, shopping and entertainment centers and educational institutions for cleaning foreign objects, large particles of dust and dirt from the incoming air;
In mechanical engineering - to remove contaminants contained in liquids and air
Galoon weaving mesh has a peculiarity - the warp wire is thicker in diameter than the weft wire. Due to this, the transmission capacity of the mesh is large, which ensures good filtration.
When using a filter mesh for wells, the quality of filtration does not depend on the rock to which the mesh is adjacent, and the mesh is tear-resistant, which is important for its use at great depths. If you need to buy a filter mesh, you should pay attention to its marking. The letters indicate the type of weaving: P - linen, C - twill, and the number after the letters indicates the number of weft wires in 1 dm³ of the mesh. So, for example, mesh P72 and above are the most fine-mesh type of material for filtration and are suitable for water purification from fine-grained and dusty sand. P60 - suitable for wells built on fine-grained sand with dusty impurities. Galloon mesh marked P56 is the best option for wells with medium-grained (particle size from 0.25 to 0.5 mm) and fine-grained (fraction from 0.1 to 0.26 mm) sand, and P48 is intended for wells only with coarse sand (grains from 0.5 to 1.0 mm and more).
The grid steel is an integral part of mechanisms in mechanical engineering. It's no secret that uninterrupted operationcar also depends on the quality of the fuel used. Any fuel already contains foreign impurities that adversely affect the operation of the engine, in addition, water, rust from the walls of steel tanks, dust and dirt from the filling nozzle get into it. Therefore, the fuel must undergo multi-stage filtration (cleaning).
Modern cars are equipped with a two-stage fuel purification system: a coarse filter (FGO), which traps impurities of more than 0.1 mm, and a fine filter (PTF), which retains particles less than 0.1 mm.
There are not only filters from the mesh for cleaning fuel, but also filters that prevent the penetration of exhaust gases and other toxins into the interior of the car. If they do not work properly, the driver and passengers may experience headaches, dizziness, allergic and other reactions. It is recommended to replace the filter elements of the car every 45 thousand kilometers.
Metal mesh for air filters is installed in special panels. Welded galvanized mesh with meshes 10x10 mm, 20x20 mm, 25x25 mm is used in the manufacture of ventilation filters, serves to fix the filter material on the side of the air inlet / outlet, helps to keep its shape and protect against damage by large particles. Welded mesh with a mesh size of 50x50 mm is also suitable for the manufacture of protective boxes for ventilation elements and serves to protect ventilation ducts from the penetration of large objects, such as birds.
Woven mesh is used in air panel filters for the purpose of preliminary (coarse) air purification from large-sized dust particles, as well as oil and grease traps in ventilation and air conditioning systems. This type of mesh has a large range of mesh sizes, so the smallest meshes from 0.2 mm and a little higher can independently perform the role of air purification.
Expanded mesh TsPVS combines the properties of both welded and woven meshes, i.e. can be used both as a reinforcing material and as an independent filtration element. Cells are used in the range from 3x3 mm to 25x25 mm.
Filter mesh is a versatile material, which, as mentioned above, is used in many areas of production. This is due to the fact that the galloon mesh has the following advantages:
Galloon weaving provides good filtration of substances with high throughput.
The filter mesh has a high tensile strength, which is a necessary factor for its use at great depths.
When using mesh for filtration in wells, the quality of filtration does not depend on the formation to which the mesh is adjacent.
Alloying steel significantly increases the service life, since corrosion processes are much slower.
Summarizing the above, we can say that the filter mesh retains its properties even during intensive operation, which significantly reduces the cost of well maintenance.
If you need to buy a filter mesh, then you should pay attention to the marking: the letters “C” (twill weave) and “P” (plain weave) indicate the type of weave, after it there is a number indicating the number of weft wires per 1 dm of mesh. For example, the mesh P72 is optimal for filtering even a fine fraction of sand, since it has very small filter cells.
