Why oxygen valves can t get grease

This is because pure oxygen reacts with grease and can cause fire. Answer Supplement Oxidation occurs to produce water, carbon dioxide, and nitric acid, which may also react directly with the valve body.

Grease is organic matter, it can be burned, oxygen can be combusted, so you can't let them meet, for fear of burning out or clogging the valve, I think so.

Can be removed. You need to use a degreaser.

Commonly used degreasers are industrial carbon tetrachloride, industrial dichloroethane, trichloroethylene, rectified ethanol, non-flammable detergents, etc. Some degreasers are toxic, some are flammable, and some are corrosive, so different protective measures should be taken according to the nature of the degreaser in use.

Degreasing method. 1. Filling and soaking method: it is often used to remove the oil stain on the inner surface of the pipe, inject degreaser into the pipe, close the end of the pipe, lay the pipe flat and soak, rotate 90° every 15 minutes to ensure that the surface of the pipe is evenly soaked and washed;

2. Wipe method: that is, wipe the oil stain on the surface of the pipe with a clean fabric dipped in degreasing agent;

3. Circulation method: that is, in the closed pipeline system, the circulating pump is used to circulate the degreaser in the closed pipe section, so that the inner surface of the pipe can be evenly soaked and flushed by the degreaser to remove the oil stain;

4. Tank immersion method: that is, the detachable parts are directly put into the tank with degreaser to soak and wash to remove oil stains. The soaking time depends on the degree of contamination.

The grease in the oxygen line must be cleaned up to meet the standard of less than or equal to 120mg m2, because the autoignition temperature of the grease in oxygen is very low and only a little ignition energy is required to burn**.

Of course, the grease in the oxygen pipe can be removed, but it must be removed by special drugs, and it is very difficult to remove it in normal times.

The grease inside the oxygen line must be cleaned or it will happen**.

The oxygen must be removed from the pipeline, because pure oxygen has strong oxidizing properties, it can promote the violent combustion of combustibles. Oils and fats meet pure oxygen, which vaporizes much faster and releases a lot of heat at the same time. The temperature rises rapidly and can quickly cause combustion.

You can choose a professional oxygen pipeline degreaser to remove grease from the inside of the pipe, and the pipe must be kept clear at both ends and there is no oxygen inside, which is safer.

The main reason why the oxygen valve can not be contaminated with grease is: First, the pressure of the oxygen valve is high pressure, if the air pressure is too high, it is contaminated with grease, there is a chemical reaction, or it reaches the combustion point of grease, then the valve will occur**!

Second, if it is contaminated first and then applied, then the grease will produce chemical deterioration in the normally closed valve body, of course, it depends on what kind of medium, if it is chlorine, the small point is that it is oxygen, the grease will be contaminated with dust, blocking all kinds of ** oxygen outlets, due to the excessive pressure, the filter is ineffective!

There's a lot more I haven't considered...

This is because pure oxygen reacts with grease and can cause fire. Oxidation occurs to produce water, carbon dioxide, and nitric acid, which may also react directly with the valve body.

There will be a chemical reaction ... There are concerns about safety.
