Stainless-steel etching filter is a type of pipeline fittings designed for reagent less prevention of ingress of persistent mechanical particles of the working medium to pipeline elements sensitive to them (pumps, control filters, meters, etc.). The cleaning efficiency of filters of this type reaches 90%.
The principle of operation of the steel mesh filter is extremely simple. The filter element passes through the working medium. It retains the mechanical impurities contained in it (dirt, rust, chips, etc.).
The filter cleans by removing the cover, removing the filter element and removing contaminants. You can use stainless-steel etching filter without depressurizing anything. It is allowed to install instead of a plug in the ball valve cover.
Moreover, one of the most common filter specifications is: carbon steel body, stainless mesh. To work with aggressive media, stainless mesh filters are good to use. The body of which comes of stainless steel.
Coarse mechanical filters are good to use for pipeline systems with various contents. At the domestic and industrial level, mesh filters install in pipelines through which flows:
We produce stainless-steel etching filter of various diameters from DN 15 to 400 mm. They design to operate at a maximum temperature of the working medium up to 400 ° C. According to the type of connection to the pipeline, steel mesh filters are etching, coupling, welded, threaded.
On the pipeline, the filters install with the cover down. The direction of movement of the working medium indicates by an arrow on the body. Moreover, it is also allowed to install filters vertically when the direction of movement of the medium is from top to bottom. When installing filters on the steam line, they place with a lid to the side to prevent the accumulation of condensate in it.
Steel mesh filters are good to use everywhere in various areas of industry and public utilities for the purification of water, steam and non-aggressive media.
Moreover, mesh filters are special flange-type drainage filter elements for coarse air or liquid purification. It is widely good to use in industrial and domestic pipelines. The mesh filter has a dense design and a mechanical way to filter the contents of the pipeline. You can do it by cleaning it from large and small particles of dirt, impurities, scale, rust, and mechanical chips.
Mesh filters install at the inlets of pipelines. Stainless-steel etching filter perform the function of the first and main degree of filtration of water, steam, air and gas from the largest polluting particles and inclusions.
Huge filtration systems of a mesh design serve as the main barrier in the process of the passage of liquid from the main sources of intake to the water supply system - at the household level. Moreover, water from the machine filters using a mesh filter from silt, sand, stones and organic elements, entering the water supply system already without the presence of large elements of dirt.
In their appearance, stainless-steel etching filter may differ. This applies to the design, as well as overall dimensions. The main part of the structure is a massive metal case with a filter mesh installed inside.
Moreover, the filter housing comes of steel, brass, copper or cast iron. In industrial and some modern domestic water supply systems, reinforced drain or flange filters made of a mixture of metal and composite materials install.
The mesh filter in professional and domestic circles is often called a "mud filter".
The principle of operation of the filter is to simply screen out large polluting particles with a volume of more than 0.2 mm. This is the minimum hole size that a dense stainless-steel etching filter has. Similarly, it comes inside the massive valve body.
As a rule, water passes through a coarse mechanical treatment system when the degree of turbidity and the number of contaminants present in it is above 1.5 mg/l. Moreover, industrial filters design for installation in pipelines with a diameter of 80 to 500 mm. The working environment, in which the strainer with special shut-off filters is mounted, has a pressure of 1.6-6.3 MPa.
Mesh filters are classified according to the location of the sump, the method of connection to the water supply, and the type of purification good to use. The first gradation divides stainless-steel etching filter into oblique and straight.
The housing with a straight filter design comes strictly on horizontal sections of piping systems. Moreover, this requires an open space above the pipes. Oblique filters are more versatile. Moreover, they are easy to install diagonally or at an angle, so they do not require a lot of free space for installation. In the two types of filters mentioned, the sump is accordingly located differently.
Moreover, the design of a direct filter is more reliable. Moreover, sump in it comes at an angle of 90 degrees to the flow of the contents of the pipe. For this reason, stainless-steel etching filter may have a larger reservoir for mud accumulation.
Filters, depending on the method of connection with the pipe, can be etching and coupling. Coupling models have a simpler design - the filter housing simply screws into the pipe hole, secured with nuts. They are good to use in pipeline networks in which the mounting hole has a diameter of no more than 2 inches.
Such mechanisms have a complex, but at the same time, more convenient design. Moreover, etching filters can easy to remove for cleaning and replacement. Stainless-steel etching filter have a mounting hole volume greater than 2 inches in diameter and install on main pipelines.
Moreover, at the industrial level, it is also customary to install the simplest coarse cleaning systems with an automatic principle of operation. Special shut-off filters in household systems have an ordinary valve that operates on the principle of unscrewing / twisting. In industrial - the valve regulate automatically by means of an actuator.
