Skärbrännaren tillför utöver skäroxygenet en bränngas, som vanligtvis är acetylen eller propan (gasol) och som antänds med oxygen (värmeoxygen), för att värma
In order to obtain the best possible result doing oxy- acetylene gas welding & cutting there are 4 Operating instruction for setting oxygen and acetylene working pressure: extraordinary temperature stability and good sealing
because of the short supply of oxygen, the flame has to travel for larger distances to completely burn. Oxygen-Lance Cutting: Oxygen lancing is an oxygen cutting process used to cut metals with oxygen supplied through a consumable tube. The oxygen lance is made of a length of small diameter (3-13 mm) black iron pipe. The lance pipe is connected with fittings and nipples and a quick-throw oxygen valve switch as shown in Fig. 19.9A. 2019-12-07 · You'll get the most bang for your buck, relatively speaking, from acetylene in oxygen (3100°C) Combustion of acetylene with oxygen produces a flame of over 3,600 K (3,330 °C; 6,020 °F), releasing 11.8 kJ/g.
If a flame is formed the temperature is about 2,800-3,000°C. 2019-03-11 Acetylene when combined with oxygen burns at a temperature of 5600 °F to 6300 °F, highest among commonly used gaseous fuels. As a fuel acetylene’s primary disadvantage, in comparison to other fuels, is high cost. Chemtane 2 Acetylene produces the highest flame temperature of all the fuel gases. The maximum flame temperature for acetylene (in oxygen) is approximately 3,160°C compared with a maximum temperature of 2,828°C with propane.
Oxygen is industrially produced by electrolysis of water or by liquidation of air and separating oxygen. The gas produced is compressed and charged into cylinder with 40 liter capacity to a pressure of about 15.4MPa at 21ºC temperature.

Flame temperature acetylene/air Flame solder S-44 and S-55. Also used for soldering brass and other copper alloys using GasIQ's copperphosphorus brazing rods. Working temperature: 500-800 °C.
Gas welding or oxygen-acetylene welding is made possible because there are some gasses that burn at extremely high temperatures. With this process, oxygen as well as acetylene are fed from holding tanks to a torch and then when needed ignited. This combination makes a gas that burns at an incredible 5500 degrees Fahrenheit.
ISO 9539, Gas welding They are suitable to be used with Oxygen, Acetylene, Propane or Natural Gas Max service pressure is 16 bar within a temperature range of -30°C to +50°C. av J Bood · 2000 · Citerat av 4 — A code for calculation of rotational CARS spectra of pure acetylene as well as mixtures of acetylene and nitrogen was developed. Using this code, temperatures Problems of the acetylene reduction technique applied to water-saturated the current slow and costly system where acetylene, oxygen and compressed air are Na2SO4 deactivation; Acetylene and propadiene elute after butanes. sieve 5A; Easily separate permanent gases at temperatures above ambient. Improve accuracy with sharp, symmetrical peaks for argon, oxygen, and carbon monoxide. scrap, metal construction using gas mixture of oxygen and acetylene, propane.
So to summarize, yes it can be a problem at -30 for someone using A LARGE torch, but not for you.

Subject-Matter of Oxy-Acetylene Flame: First we have to study combustion which is closely associated with the properties of oxygen.

2005-04-06 · For flames in air, the temperature, humidity, pressure, present gas mixture, etc. of the air The mixture of fuel vs. oxidixer in use. For example, an acetylene/oxygene flame may be neutral (equal mix: complete combustion, white rounded cone); carburising (excess acetylene: large smoky yellow flame); or oxidising (excess oxygen: short, sharp inner cone, deeper purple hissing flame).
Gas welding – this generally uses a combination of oxygen and acetylene. Fakta 2: Gasernas tillstånd och tryck.

Table 8-1 shows the maximum temperature achievable with these alternative fuel gases as compared with the temperature of acetylene. These other fuels work well for soldering, brazing, preheating and oxygen cutting, but are seldom used for welding.
