The problem of stainless steel pipe factory, what school to study in stainless steel pipe factory?

According to the medium sulfur content, 1%, about 100 million cubic meters of flue gas, about 10,000 tons of carbon dioxide, about 380-440 tons of sulfur dioxide, and about 240-300 tons of nitrogen dioxide are emitted, which is the daily emissions. According to the presence of nitrogen dioxide in the air, it is harmful to health. This does not include the amount of dust that is discharged.

What is called 100 million cubic meters is the amount of air in 10 kilometers long, 10 kilometers wide and 1 meter high.

It should be added that at present, the global process of nitrogen denitrification is not mature, and few manufacturers have denitrification. Generally, there are desulfurization devices in new manufacturers, and the desulfurization rate is about 80-90%. Generally, it is electrostatic precipitator, the larger dust is removed, and the dust content can reach 30-50 mg standard rice after dust removal, and unfortunately the rest is easy to adsorb on the blood vessels in the lungs.

In the Olympic year, advocating a green Olympics is the focus of this year, and it should be reported to the competent authorities.

I don't know what type of stainless steel that stainless steel factory produces.

Stainless steels can be broadly classified by application, chemical composition, and metallographic structure.

Based on the austenitic steel composed of 18% chromium to 8% nickel, the amount of each element varies according to the amount of each element, and the steel grades for various purposes are developed.

1 Classification by chemical composition:

CR series: ferritic series, martensitic series.

CR-Ni series: austenitic series, anomaly series, precipitation hardening series.

2 Classification by metallographic organization:

Austenitic stainless steel.

Ferritic stainless steel.

Martensitic stainless steel.

Duplex stainless steel.

Precipitation hardening stainless steel.

There should be a lot of additives in smelting, and yellow smoke should be an acid gas produced by sulfides.

300 meters should be considered a very close point.

How strong it is.

Whether it exceeds the standard. Local environmental authorities should be consulted.

Or let them measure.

The specific harm is difficult to say without accurate data from the relevant departments.

I hope you don't think too much without consulting the environmental authorities.

Otherwise, you will be worried.

Disrupting their own lives.

Oh, and there's even a weird smell.

Then you should report it immediately.

Because the smell alone affects our normal life.

I hope you can be brave enough to defend your living environment.

You can also report it to **.

Enterprises are required to suspend production for rectification, or even close production lines.

Call the Environmental Protection Bureau: 12369 or the Environmental Protection Bureau of the People's Republic of China (report)**.

This is the year of the Olympics, isn't it advocating a green Olympics?

June 5 is Earth Day.

Where is your home?

Oh. Wu Jin.

Wujin TV doesn't have a program called "Life Connection", which pays attention to people's livelihood.

Just hit it** is 5286666

No, I'm reporting it to my superiors.

This gas is very harmful to the human body, hurry up to the environmental protection department to report, now is just about to open the Olympics, can they still pollute the environment? All departments will actively deal with it and avoid continuing to endanger people's physical and mental health!!

Anyway, it's not good for the human body

The acid mist removed by pickling must be treated.

The ** department and the sanitation department should immediately report this situation, and it can't be delayed any longer.

Hurry up and get it. No, call 110, forget it, let them find the answer.

Summary. Hello, for your question How to deal with the surface of the stainless steel pipe factory: 1. Polishing treatment: The surface of the 304 stainless steel water pipe is polished on the crystal surface, and the polished stainless steel pipe is very bright.

Hello, for your question How to deal with the surface of the stainless steel pipe factory: 1. Polishing treatment: The surface of the 304 stainless steel jujube hole water pipe is polished, and the polished stainless steel pipe is very bright.

2. Pickling passivation: Put the 304 stainless pipe into the pickling pool for pickling, and form a protective comic film on the surface of the stainless steel pipe to protect the stainless steel pipe from corrosion.

When brown rust spots (spots) appear on the surface of stainless steel pipes, people are surprised: they think that "stainless steel is not rusty, rust is not stainless steel, and there may be a problem with the steel". In fact, this is a one-sided and erroneous view of the lack of understanding of stainless steel.

Stainless steel can also rust under certain conditions.

Stainless steel has the ability to resist atmospheric oxidation--- that is, stainless steel, and also has the ability to resist corrosion in media containing acid, alkali and salt--- that is, corrosion resistance. However, the size of its corrosion resistance is changed with the chemical composition of the steel itself, the state of the additive, the use conditions and the type of environmental medium. For example, 304 steel pipe, in a dry and clean atmosphere, has absolutely excellent rust resistance, but if it is moved to the coastal area, it will soon rust in the sea fog containing a lot of salt; The 316 steel pipe performed well.

Therefore, not any kind of stainless steel can resist corrosion and rust in any environment.

Stainless steel is a layer of extremely thin and strong and fine stable chromium-rich oxide film (protective film) formed on its surface to prevent the continued penetration and oxidation of oxygen atoms, and obtain the ability to resist corrosion. Once for some reason, the film is constantly damaged, the oxygen atoms in the air or liquid will continue to seep in or the iron atoms in the metal will continue to precipitate out, forming loose iron oxide, and the metal surface will be constantly corroded. There are many forms of destruction of this kind of watch, and there are several common ones in daily life:

1. The surface of stainless steel contains dust or attachments of foreign metal particles, and in the humid air, the condensation between the attachment and stainless steel connects the two into a microbattery, which triggers an electrochemical reaction and destroys the protective film, which is called electrochemical corrosion.

2. Organic juice (such as melon and vegetables, noodle soup, phlegm, etc.) adheres to the surface of stainless steel, and in the presence of water and oxygen, it constitutes organic acid, and the organic acid corrodes the metal surface for a long time.

Hello Answer! Stainless steel pipes are not easy to rust, which has a lot to do with the composition of stainless steel. However, if the leaves are on the stainless steel for a long time, it will corrode the stainless steel, and the corroded stainless steel will eventually rust.

Stainless steel industrial pipes are not all seamless, please refer to the national standard GB T 28708-2012 "Seamless and welded steel pipe size selection regulations for pipeline engineering" for details.

Chemical plants use a large amount of stainless steel pipes.

Generally, it is necessary to use water for cooling, and factories that use these pipes to discharge sewage, automobile manufacturing, paper industry, environmental protection industry, etc., all need to use it, and the demand will be high. Broad Stainless Steel is a professional manufacturer of stainless steel industrial pipes.

1. The stainless steel does not rust mainly depends on the material of the stainless steel pipe itself, and it is also related to the installation environment of the stainless steel pipe.

2. If you want to prolong the life of stainless steel pipe fittings and reduce stainless steel corrosion and rust, in addition to choosing a regular stainless steel manufacturer to ensure the material of stainless steel pipe fittings, later maintenance is also very important, such as in the acid rain weather is more frequent, or in coastal areas, regular maintenance should be taken on stainless steel pipe fittings. Thus improving the service life of stainless steel pipes.

3. If there is a slight rust spot, you can take a little rust removal paste to further expand the rust point and reduce the corrosion point. Because of this, it is essential to choose and use stainless steel pipes correctly. The correct choice is to select stainless steel pipes according to the requirements of specific use conditions.

Reasonable use is to use the stainless steel pipe fittings with stainless steel and corrosion resistance.

4. Wrong choice or unreasonable use will make the stainless steel pipe rust and corroded. Problems with the quality of stainless steel pipe fittings can also lead to rust and corrosion of stainless steel pipes. Therefore, the quality of stainless steel pipe fittings is the premise of the correct selection and reasonable use of stainless steel pipe fittings.

Many people think that stainless steel pipes will definitely not rust, which is a wrong one-sided view. First of all, the stainless steel pipe is conditioned for its stainless steel rust and corrosion resistance. Stainless steel pipes are steel pipes that do not rust in weak corrosive environments such as atmosphere and fresh water, and the chromium content in the steel must be 12%.

Rust will occur if the chromium content is low or if it is not used in a weakly corrosive environment such as the atmosphere (including in a weakly corrosive environment such as the atmosphere, but under the condition of concentration of Cl-local enrichment). Acid-resistant steel pipe is a steel pipe that is corrosion-resistant in strong corrosive media such as acid, alkali and salt, but it is also corrosion-resistant under certain conditions, such as medium type, temperature, concentration, impurity content, flow rate, pressure, etc. There is no stainless steel pipe in the world that does not rust and is corrosion-resistant under any conditions.

Because of this, we must choose and use stainless steel pipes correctly. The correct choice is to choose stainless steel pipes according to the requirements of specific use conditions. Reasonable use is based on the stainless steel and corrosion resistance characteristics of stainless steel pipes.

Wrong choice or unreasonable use can cause stainless steel pipes to rust and corrode. Problems with the quality of stainless steel pipes can also lead to rust and corrosion of stainless steel pipes. Therefore, the quality of stainless steel pipes is the premise of the correct selection and rational use of stainless steel pipes.

Metals rust and non-rust are relative, there can be no metal that is absolutely rust-free, and even gold and platinum, which are the least likely to rust, will corrode and rust when they encounter solutions with particularly strong metal dissolving capabilities, such as aqua regia.

Especially when exposed to chloride ions, stress corrosion or grain boundary corrosion occurs.

There may be several reasons for the rusting of 304 materials:

1.Chloride ions are present in the environment of use.

Chloride ions are widely present, such as table salt, sweat stains, sea water, sea breeze, soil, etc. In the presence of chloride ions, stainless steel corrodes very quickly, even more than ordinary mild steel.

Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently, dust removed, and kept clean and dry.

316 and 317 stainless steels (see below for the properties of 317 stainless steel) are molybdenum-containing stainless steel grades. The molybdenum content in 317 stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in the steel, the overall properties of this steel grade are better than those of 310 and 304 stainless steels, and under high temperature conditions, when the concentration of sulfuric acid is less than 15% and above 85%, 316 stainless steel has a wide range of uses.

316 stainless steel also has good chloride attack properties, so it is commonly used in marine environments.

Theoretical weight of stainless steel pipe: w = (outer diameter - wall thickness) x wall thickness.
