How much acetylene can be used per hour?
An acetylene cylinder with 360 cu. ft. can supply 36 cubic feet per hour (CFH) with intermittent use and only 24 CFH in continuous use. This makes manifolding of acetylene cylinders a must in heavy-duty applications.
What is the ratio of oxygen in gas cutting?
Propane has a greater stoichiometric oxygen requirement than acetylene; for the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1.2 to 1 for acetylene and 4.3 to 1 for propane.
What gas is required for oxy fuel cutting?
Oxyfuel cutting operations can use gasses such as oxygen, acetylene, MAPP, natural gas and propane.
How long will a 80 CF acetylene tank last?
80 CF Oxygen tank. This is a new 80 CF high pressure gas cylinder with a cap. It has a CGA-540 valve for oxygen, and has a valid 10-year hydro test. It can be various colors, though the color is usually green, as pictured.
What is the maximum withdrawal rate of acetylene cylinder?
Acetylene is limited to a maximum continuous withdrawal rate of 1/7 of the cylinder’s rated capacity when full. Example: An acetylene cylinder that has a capacity of 330 cubic feet has maximum withdrawal rate of 47 cubic feet.
What is the capacity of acetylene cylinder?

What is the ratio of oxygen and acetylene gas?
For the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1,2 to 1 for acetylene and 4.3 to 1 for propane.
What is the ratio of oxygen to acetylene supplied at the torch tip?
The neutral flame has a one-to-one ratio of acetylene and oxygen. It obtains additional oxygen from the air and provides complete combustion. It is generally preferred for welding.
Which fuel gas requires the largest amount of oxygen from the torch?
For the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1,2 to 1 for acetylene and 4.3 to 1 for propane. So, there is far more oxygen being consumed when using Propane.
Which fuel gas can be used to cut low carbon steel?
Oxy-fuel cutting is used for the cutting of mild steel. Only metals whose oxides have a lower melting point than the base metal itself can be cut with this process.
What does the B in B tank stand for?
“BUS” is the name of the B. A “MC” tank is a 4” diameter and 15” tall acetylene tank. The MC stands for motorcycles.
What is the pressure in acetylene cylinder?
The working pressure of acetylene equipment is critical: Acetylene pressure must not exceed 0.62 bar (9psi) unless equipment has been specifically designed for it.
How is acetylene measured?
The only way you can see for yourself how much acetylene is inside your cylinder is to weigh it and subtract the tare weight from the gross weight of the cylinder, this then gives the nett weight of the acetylene.
How much gas is in a size 300 cylinder?
300 (HH) 305 cu. ft. Argon 3600/6000 P.S.I.
What is gas cylinder size?
45kg gas bottle have a cylinder capacity of 88 litres. The standard cooking gas cylinder weight in India (fuel tank weight) has a gas cylinder weight of contents of 14.2kg ± 150 grams. Domestic cooking gas cylinder weight (fuel tank weight) is about 29.5kg for a full 14.2kg cooking gas cylinder.
What is the ratio of oxygen to acetylene in oxidising flame?
Oxidising flame: flame with an excess of oxygen. 2.3:1 ratio of oxygen and acetylene. 1.5:1 ratio of oxygen and acetylene is correct.
What is the gas ratio of oxidizing flame?
Oxidizing flame: An Oxidizing oxyacetylene flame is produced when more oxygen is burnt with less amount of acetylene. The oxygen to acetylene ratio in the case of Oxidizing flame is 1.15 to 1.5.
What is the ratio of oxygen and acetylene for complete combustion?
2.5:1
Complete combustion of a hydrocarbon occurs when oxygen gas in the surrounding air mixes completely and is present in the stoichiometric mole ratio to react completely with the amount of hydrocarbon. For acetylene, the mole ratio is five moles of oxygen per two moles of acetylene, or 2.5:1.
What is oxyfuel cutting?
Oxyfuel cutting – process and fuel gases Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.
How much does the purity of oxygen affect gas cutting time?
In the range of oxygen purity from 97.5% to 99.5%, the gas cutting time will increase by 10% to 15% for each 1% decrease in oxygen purity for a 1m long cut; the oxygen consumption will increase by 25% to 35%. Therefore, the purity of oxygen for gas cutting should be improved as much as possible, generally requiring more than 99.5%.
What gas is used for cutting?
The cutting method uses both oxygen and a cutting gas. But a variety of different gases are available. Oxy acetylene cutting has pretty much become synonymous with oxyfuel cutting. The reason is that this is the most common fuel used in the process. The main reason for that is the temperature it can achieve – around 3200° C.
What is the ratio of oxygen to propane in a flame cutter?
The ratio of oxygen to propane is around 4.3:1. Thus, reaching the maximum temperature requires around 3.5 times more oxygen than oxy acetylene cutting. Propylene is fast catching up with acetylene in the extent of use for flame cutting. There are several reasons for that.
