Acetylene Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.

Acetylene: Safe Transport & HandlingSecure it. Ventilate it. Respect it. Acetylene: Safe Transport & Handling Secure It. The benefits of acetylene for welding and cutting are well documented. Excellent thermal properties make it much more effective at cutting than other fuel gases, offering productivity gains of around 33 percent relative to propane, for instance.

What is an Acetylene Torch? Water or other cooling agents may be used to assist the cooling process. Cutting. Acetylene can also be used to cut metal objects. In this scenario, an acetylene torch is used to heat the metal to a kindling temperature while a stream of pure oxygen is applied to the desired area.

Acetylene The energy richness of the C≡C triple bond and the rather high solubility of acetylene in water make it a suitable substrate for bacteria, provided an adequate source is available. A number of bacteria living on acetylene have been identified.

Acetylene: Safe Transport & HandlingSecure it. Ventilate it. Respect it. What is perhaps not so well known is the fact that acetylene – because of its high flammability – can present a serious safety hazard. So cylinders containing acetylene, like all gas cylinders, should be transported, stored and handled properly to ensure they are completely safe. Unfortunately, safety is not always accorded the importance it deserves.

Welding Instructional Fabrication | 5. Introduction to. Oxy-Acetylene Welding. Oxy-Acetylene, commonly known as Oxy-fuel, is one of the. oldest welding processes, though in recent years, it has become. less popular in industrial applications. However, it is still widely. used for a variety of applications. Oxy-fuel equipment is versatile, lending itself to welding, brazing, braze-welding, silver soldering, metal heating (for bending and forming) and oxy-fuel cutting. This book will highlight the welding and cutting processes.

- Figure 15-26.—Two-stage regulator. working pressure is held constant, and pressure adjustment during welding operations is not required. A two-stage regulator is shown in figure 15-26. The acetylene regulator controls and reduces the acetylene pressure from any standard cylinder that contains pressures up to 500 psi. It is of the same general design as the oxygen regulator, but it will not withstand such high pressures.
