Do you need a Licence for acetylene?
Acetylene gas poses an additional hazard to other flammable gases as it is also reactive. Also, those wishing to manufacture, compress and/or fill cylinders (defined in the ASR 2014) with compressed acetylene gas (defined n the ASR 2014) will be required to hold a licence to do so.
Which is cheaper propane or acetylene?
Propane has greater stoichiometric oxygen requirements than acetylene. So, there is far more oxygen being consumed when using Propane. Despite Propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.
How long will 10 cubic feet of acetylene last?
10 cf tank / 7 = 1.42 cubic feet safe withdrawl per hour. 3 CFH / 60 minutes in an hour = 0.05 cubic feet per minute. So by this math it it safe to say I could get 28 minutes of safe run time at 3 CFH and 14 minutes safe run time at 6 CFH before I violate the 1/7 rule and start sucking acetone?.
How do you make homemade acetylene?
It is created by mixing lime and coke in a blast furnace. The product manufactured is calcium carbide. It is reacted with water to create acetylene gas, and this reaction can be easily formulated as CaC2 + 2H2O → C2H2 + Ca (OH)2. Acetylene, calcium hydroxide and heat are the byproducts of this reaction.
What do you turn off first oxygen or acetylene?
We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.
Is acetylene more flammable than propane?
The flammability limit of acetylene in the air is 2.5% to 82%, whereas that of propane is 2.1% to 9.5%. High Quality Welding: It is a well-known fact that acetylene produces a sharp and focused flame more than propane.
Can I use an oxy acetylene torch with propane?
The Oxy-Acetylene regulator set can be use with Mapp gas or propane interchangeably without issue.
Can I use a propane tip with acetylene?
You certainly can and it will work great if you use propane or mapp as the fuel gas. You will simply melt the tip or backfire with acetylene.
Can you use compressed air instead of oxygen for cutting?
No. It is not the quantity of air you need, but the concentration of oxygen present in the air. Air normally contains approximately 19% oxygen- compressing the air does not increase the oxygen content of the air. For oxy-fuel torches and burners you need oxygen- not air, which is 100% oxygen.
How long does welding oxygen last?
How many hours does an oxygen tank last? An oxygen tank lasts between 30 minutes and 2 hours depending on the tank capacity.
How long does welding gas last?
How Long Does An Argon Gas Tank Last? Welders using an average-sized tank of argon with a flow rate of about 20-25 CHF should expect a welding time of about 10 hours.
How long does an argon bottle last?
Your flow rate is usually set from 10-20 cfh which on average if you had a 250 cf bottle would last for 10-20 hours of welding non stop. That would work out to about 2-4 days of serious welding.
Can you make your own acetylene?
You pay no outside concern for making acetylene, putting it into cylinders and transporting it to your shop or factory. You make your own acetylene – in the quantity required right on the job as you use it.
Can you still buy carbide?
Despite these problems there are three dealers that sell calcium carbide: Inner Mountain Outfitters, Karst Sports, and Rocksports Emporium. You can find both Inner Mountain Outfitters and Rocksports Emporium at different caving conventions, and it may be possible to buy calcium carbide from them face to face.
How do you make a gas torch?
Step 1: Drill the Bottle Cap. Make a suitable hole in the bottle cap enough to join it with the syringe pipe. Step 2: Connect the Syringe End With Bottle Cap. Step 3: Apply Hot Glue. Step 4: Fill the Bottle With Calcium Carbide. Step 5: Pour Some Water. Step 6: Ignite the Torch.
Why does my cutting torch make popping noise?
The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage.
How far do you open an acetylene tank?
The cylinder valve shall always be opened slowly. An acetylene cylinder valve shall not be opened more than one and one-half turns of the spindle, and preferably no more than three-fourths of a turn.
Can you use acetylene hose for LPG?
Here’s the rub, you CANNOT use Acetylene Equipment for Propane or Propylene! Sorry about that, but the internal materials are different and Propane will corrode the internal materials that Acetylene equipment is made of (Propylene is around 50% Propane).
What is the most explosive gas?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Is MAPP gas hotter than acetylene?
Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during transport, allowing a greater volume of fuel gas to be transported at the same given weight, and it is much safer in use.
