Why cannot acetylene bottles be inverted

Because acetylene is a flammable and explosive substance, when placed upside down, acetone will sink into the pressure reducing valve, rubber tube, etc., blocking the acetylene gas path, which is prone to backfire and causing explosion accidents. In addition, the cylinder valve is the most fragile. When the cylinder valve is broken, the high-pressure gas inside the cylinder suddenly sprays out, causing the cylinder to rush in the opposite direction, causing personal injury and death when it collides with the human body. Therefore, acetylene cylinders should be explosion-proof in essence and should not be placed upside down, Let me explain to you why acetylene bottles cannot be inverted? Let's take a look together with the editor!

Acetylene, Molecular formula C2H2, commonly known as wind coal or carbide gas, is one of the smallest alkyne compounds and is mainly used for industrial purposes, especially for welding metals. Acetylene is a colorless and highly flammable gas at room temperature. Pure acetylene is odorless, but industrial acetylene has a smell of garlic because it contains impurities such as hydrogen sulfide and Phosphine.
