Can the acetylene bottle be inverted when the air pressure is insufficient?

Acetylene bottle is a container for storing and transporting acetylene. The shape is similar to that of an oxygen cylinder, but its structure is more complicated than that of an oxygen cylinder. Dissolved acetylene and oxygen are widely used in welding and cutting in the production process, and in most cases they are used at the same time. Gas acetylene is combustible gas, and oxygen is combustion-supporting gas.

Acetylene bottles are very common on construction sites.

However, once the gas cylinder is improperly placed,

Equivalent to a "time bomb"

Operators also have clear requirements in their daily work.

Acetylene cylinders must not be inverted, but must be placed upright!

Maybe you have remembered this requirement.

But do you know why?

Tell you now.

Why can't acetylene cylinders be placed upside down or horizontally!

Original reason 1 0 1

Acetylene bottles contain fillers and solvents (acetone). When they are used horizontally, acetone can easily flow out with acetylene gas, which will not only increase the consumption of acetone, but also reduce the combustion temperature, thus affecting the use. At the same time, it will cause tempering and cause an explosion accident of acetylene bottle.

Original reason 2 02

When the acetylene bottle is placed horizontally, it is easy to roll, and objects such as bottles are easy to collide, forming excitation energy, which leads to accidents of acetylene bottles.

Yuanyinsan 03

Acetylene bottles are equipped with shockproof aprons to prevent collisions during loading, unloading, transportation and use. An apron is an insulating material. Horizontal placement refers to placing acetylene cylinders on electrical insulators, so that the static electricity generated on the cylinders cannot spread to the earth and gather on the cylinders, which is easy to generate electrostatic sparks. When acetylene gas leaks, it is easy to cause combustion and explosion accidents.

Original reason 4 04

When in use, the valve of acetylene cylinder is equipped with pressure reducer, flame arrester and rubber hose. Because it is easy to roll when lying down, it is easy to damage the pressure reducer, flame arrester or degumming tube when rolling, which leads to acetylene gas leakage and combustion explosion.

There is one more thing to pay special attention to.

Oxygen cylinders and acetylene cylinders cannot be put together.

They explode easily when put together.

Therefore, we should pay attention to the following three points.

▼▼▼

1

Gas cylinders must be firmly placed, transported and erected on site, and installed on special vehicles (racks) or fixtures.

2

The distance between the acetylene cylinder and the oxygen cylinder shall not be less than 5m, and the acetylene cylinder shall not be placed horizontally, and the distance from the hot spot shall not be less than10m. Do not expose to the sun, and keep away from radiators, piping systems, circuit wiring and objects that may be used for grounding (such as electric welding machines).

three

It is forbidden to weld near the place where inflammable and explosive articles are stored; When welding near combustible materials, it must be 5 meters away; When welding in the open air, a wind-proof device must be set to avoid sparks flying and fire.
