The color of acetylene cylinder (C2H2) is white and the font is red.

acetylene is active, explosive and extremely dangerous. The molecular structure of acetylene is unsaturated bond at normal temperature and pressure, which is very unstable when heated. When the temperature is higher than 2oC, the polymerization reaction will occur, which will lead to the continuous increase of temperature and pressure, which will lead to explosion. When acetylene is mixed with metals such as copper and silver, air and pure oxygen, it will even cause explosion when the diameter of the container is large.

When using acetylene gas to cut carbon steel, it is easy to cause the phenomena of melting the upper edge of the cut, too much slag hanging and difficult to remove, and local hardening of the cut surface, which makes the cutting process unsatisfactory. At the same time, during the safety period, 14 kilograms of acetone should be added to the dissolved acetylene cylinder according to the regulations, and 5-7 kilograms of acetylene should be charged according to the regulations to achieve the purpose of completely dissolving in it.

Notes:

1. When acetylene cylinders are used, transported and stored, the ambient temperature shall not exceed 4℃.

2. The paint color of acetylene bottle must be kept intact and shall not be altered arbitrarily.

3, acetylene cylinders must be equipped with special pressure reducer when using. The flashback preventer must be checked before working, otherwise it is prohibited to use it. When it is opened, the operator should stand at the side and rear of the valve, and the action should be gentle.

4. The service pressure shall not exceed .5Mpa, and the gas transmission flow shall not exceed 1.5-2. m3/hr..

5. When using, pay attention to fixation to prevent toppling. It is forbidden to lie down and use. For acetylene bottles that have been lying down, it is not allowed to use directly. Before using, you must stand still for fifteen minutes, and then use the pressure reducer, otherwise it will be dangerous. Knocking, collision and other rude behaviors are prohibited.
