What is the maximum pressure used for delivery of acetylene?

Answer :

Maximum amount of pressure Under no circumstances shall acetylene be generated, piped (except in approved cylinder manifolds), or used at a pressure greater than 15 psig (103 kPa gauge pressure) or 30 psia (pounds per square inch of pressure) (206 kPa absolute).

How much acetylene can be used safely at its maximum working pressure is the question here.

Acetylene Regulator Operating Pressure Maximum. Acetylene line pressures greater than 15 psig are extremely DANGEROUS to the operator. When more than 15 pounds of pressure is applied to acetylene gas, it can become unstable and violently decompose, making it imperative that pressure never exceed 15 pounds per square inch (psig) when working with university equipment.

What should the settings be for my oxygen and acetylene, as well?

 OXY/ACETYLENE RULE OF THUMB (MULTI-HOLE CUTTING TIPS, OXY) The recommended oxy/acetylene cutting tip pressures vary depending on the size of the cutting tip. If you don’t have access to manufacturer settings and you’re cutting steel that’s less than 1 12 inches thick, set the acetylene regulator to 10 psig and the oxygen regulator to 40 psig to get the job done.

Specifically, what is the normal working pressure for acetylene in this context?

In general, the acetylene pressure should be set to about 10 psi, and the oxygen pressure should be set to about 40 psi, according to the manufacturer’s instructions.

What happens to acetylene at pressures greater than 15 psi?

Acetylene will not explode when exposed to low pressure and normal temperature conditions. The material, however, becomes unstable and spontaneously combustible when subjected to pressures greater than 15 psi. It becomes self-explosive when the pressure exceeds 29.4 psi, and even a minor shock can cause it to explode even in the absence of air or oxygen.

What is the pressure of an acetylene tank that is completely full?

A full acetylene cylinder with a pressure of 250 psi at 700 degrees Fahrenheit (1725 kPa at 20 degrees Celsius) will have a pressure of 315 psi at 900 degrees Fahrenheit (2175 kPa at 310 degrees Celsius) and a pressure of 190 psi at 500 degrees Fahrenheit (1300 kPa at 90C). When estimating how much acetylene is in a cylinder, it is always necessary to take the temperature into consideration.

What is the source of the acetylene explosion?

It easily combines with air to form an explosive mixture. Thermal decomposition results in the production of carbon monoxide, which is toxic. Acetylene can explode violently if the pressure of the gas exceeds approximately 200 kPa (39 psi) when it is in a gaseous state, or if it is in a liquid or solid state.

What is the danger of acetylene?

Acetylene presents a unique set of risks due to its high flammability and instability, as well as its specific storage and transportation requirements. Acetylene is a highly unstable chemical compound. High pressure or temperatures can cause decomposition, which can result in a fire or an explosion if not addressed promptly.

When does acetylene become unstable, and at what temperature?

It is an unstable gas that will violently decompose if exposed to pressures greater than 15 psi. What Exactly Is Acetylene? state greater than 15 psi The auto-ignition temperature ranges between 763 and 824 degrees Fahrenheit.

What is the maximum operating pressure that acetylene should never be subjected to during operation?

Working with acetylene entails the following steps: Acetylene is as dangerous as, if not more so than, oxygen in terms of explosions. It becomes unstable at pressures greater than about 15 psi, and as a result, you should never operate your acetylene regulator at pressures greater than that.

Is it possible to lay down acetylene tanks?

Acetylene cylinders should not be placed on their sides. It is recommended that you set an acetylene tank upright for at least one hour before using it if it has been left on its side by accident. You should avoid attempting to refill or mix gases in a cylinder at any time.

When brazing, what pressure should be used for the oxygen and acetylene mixtures?

Setting the copper brazing regulator to a specific value. For silphos brazing copper HVAC line sets, the teacher told us to always set the acetylene to 7 psig and the oxygen to 15 psig when we were in school learning about the subject.

Do you use more oxygen or acetylene than you used to?

For acetylene and propane, the volume of oxygen to fuel gas ratios are 1,2 to 1 for the highest possible flame temperature in oxygen, and 4.3 to 1 for acetylene and propane, respectively. As a result, when Propane is used, significantly more oxygen is consumed. Despite the fact that propane is less expensive than acetylene, the lower cost is offset by the higher oxygen consumption of propane.

What do you turn off first, the oxygen or the acetylene in the air?

When turning off an oxy-fuel torch system, we recommend that the oxygen valve be closed first, especially if Acetylene is being used as the fuel. This is only a portion of the comprehensive safe operating procedure for torches recommended by Harris, but it is an extremely important portion.

What is the PSI of a fully charged oxygen cylinder?

A full cylinder will have a pressure reading of approximately 2000 psi (pounds per square inch).

What is the best way to tell when my acetylene tank is empty?

You can find the tare weight stamped on the side of your cylinder. Weigh the cylinder and subtract the tare weight from the total weight. Acetylene has a volume of 14.5 cubic feet per number, so you can figure out how much you have.

Why is it important to keep the acetylene cylinder upright?

Acetylene cylinders should be stored upright. It is especially important to store acetylene cylinders upright in order to prevent the gas from separating from the acetone during storage. The importance of this is so great that cylinders should be allowed to rest for at least 1-2 hours after being moved around in the workplace or having just been delivered from the supplier.

What exactly is meant by “workplace pressure?”

Working Pressure (WP) is the normal operating pressure at which a component is designed to operate continuously with a safe margin below the point at which the material will yield or burst. It is measured in pounds per square inch of working pressure. Design working pressure and maximum working pressure are other terms for the same thing.

What is the proper way to turn off an oxygen acetylene torch?

After that, close the acetylene hand valve on the torch and finally the oxygen hand valve. This puts out the flames and removes the soot from the area. Turn regulator adjusting screws all the way out after opening the torch hand valves and bleed lines. Then close the torch hand valves and bleed lines.
