Anti-corrosion measures and application of anti-corrosion flow meter

Abstract: The anti-corrosion measures and application information of anti-corrosion flow meters are provided by excellent flow meter and flow meter manufacturers. In the industrial production process, there are tiny or extremely strong corrosive media due to the need to measure the production. Corrosion is the phenomenon in which metals are damaged by chemical action in their environment. All metals and alloys can be resistant to corrosion in certain environments, however. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of anti-corrosion measures and application articles of anti-corrosion flow meters. In the industrial production process, there are tiny or extremely strong corrosive media due to the need to measure the production. Corrosion is the phenomenon in which metals are damaged by chemical action in their environment. All metals and alloys can be resistant to corrosion in certain environments, but sensitive to corrosion in others. The corrosiveness of the medium seriously threatens the service life and performance of the flow measuring instrument, and only individual ones, such as the clamp-on ultrasonic flowmeter, are less affected by the corrosion. Regardless of whether the flowmeter can measure corrosive media, anticorrosion measures must be taken for the flowmeter. (1) To avoid the heavy and the light is to choose the measurement plan reasonably based on the in-depth understanding of the technological process and the characteristics of the relevant medium, which also achieves the purpose of measuring or controlling the production process, avoiding the highly corrosive parts, and choosing the more corrosive parts. Light parts, or even change the type of parameters to be adjusted, for example (if feasible) to replace the flow fixed value adjustment system with liquid level uniform adjustment or other suitable variable adjustment, so as to avoid the problem of corrosion resistance of flow measuring instruments. (2) There are many kinds of lining materials for electromagnetic flowmeter measuring tube for corrosive conductive liquid, among which polytetrafluoroethylene has the best corrosion resistance; there are also several kinds of electrode materials, which can meet the needs of most The needs of corrosive media; the diameter of the measuring pipe is from a few millimeters to 3m, and the various specifications are complete, which can meet the needs of various measuring ranges; if the fluid temperature is also within the allowable range, it will be an ideal choice. But if the fluid doesn't conduct electricity, the electromagnetic flowmeter can't do anything about it. (3) Regular replacement of the instrument The corrosion of the corrosive medium to the metal is varied. Some corrosion is very fast, that is, general corrosion; some corrosion is slight, and the speed is very slow, that is, localized corrosion. When using the instrument, replace the instrument in time according to the corrosion condition. (4) The flanged differential pressure gauge is used to select a glass-ceramic orifice plate with excellent corrosion resistance, and the flanged differential pressure transmitter is installed on the pressure guiding nozzle. The isolation diaphragm of the transmitter is made of molybdenum-containing Pound steel, and stick a layer of Teflon isolation on the diaphragm. (5) Use an isolator to isolate the instrument with poor corrosion resistance from the strong corrosive fluid. The corrosion-resistant flowmeter has the advantages of reliability, accuracy, stability and high measurement range, and can meet the needs of various working conditions. It can measure the volume flow of various conductive liquids. The measured corrosive media include acid and alkali. , strong corrosive liquids such as salt, raw water, cooling water, pulp, mud, coal slurry, ore pulp, syrup, corn steep liquor, fiber pulp, grain pulp, lime milk, hydrogen peroxide, sea water, beer, wort, milk and various beverages Equal conductive liquid and solid-liquid two-phase liquid. This product is mainly used in petrochemical, steel, electric power, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as municipal environmental protection, water conservancy and other fields. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
