Code Of Practice 5, The Design and Construction of Manifolds using Acetylene Gas from 1.5 to 25 Bar, Revision 3
Year: 2016 Language: english Author: BCGA Genre: Practical guide Format: PDF Quality: eBook Pages count: 36 Description: Acetylene has unique properties. Acetylene is an extremely flammable gas and can burn in the presence of air or oxygen. This generates very high flame temperatures, which is the reason why acetylene is so effective for cutting and welding. The acetylene (C2H2) molecule, however, if initiated by heat exposure of a cylinder in a fire, or through excessive fill pressure, can also decompose breaking up into one hydrogen molecule and two carbon atoms. This reaction delivers much less energy than combustion but can, in some circumstances, be strong enough to rupture a cylinder. Additionally, whereas acetylene is very soluble in the solvents used in dissolved acetylene cylinders, hydrogen, when released through decomposition, is much less soluble; giving a significant and irreversible pressure rise within the cylinder, which can be sufficient to cause its rupture. For these reasons the maximum working pressure of an acetylene cylinder is kept relatively low at 19 bar. Consequently, manifolds connected to an acetylene cylinder are designed and constructed to operate at pressures between 1.5 and 25 bar. In use, acetylene is delivered to the end user at pressures up to 1.5 bar.
