OSHA standard, 1910.253(a)(2) says:
Maximum pressure. Under no condition shall acetylene be generated, piped
(except in approved cylinder manifolds) or utilized at a pressure in excess of 15
psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute). ... This requirement
is not intended to apply to storage of acetylene dissolved in a suitable solvent in
cylinders manufactured and maintained according to U.S. Department of
Transportation requirements, or to acetylene for chemical use. The use of liquid
acetylene shall be prohibited.

∙ 12y agoThe maximum safe working pressure with acetylene is 15 PSI, though most regulators and torches will cap flowrates well below this pressure. Because of the way acetylene is stored (high pressure, room temperature liquid form with small particles of balsa, charcoal, etc. in the tank) it requires time to absorb enough heat to allow some of the liquid to vaporize. If drawn too fast, you can either freeze your tank's valve, possibly damaging it dangerously, or draw liquid acetylene through your hose and have a big fiery mess right in your face as liquid acetylene hits the air and explosively evaporates and burns.

How do you test a co2 cylinder?
Measure the weight of the full cylinder and note down as m1Note down the tare weight of the cylinder marked on the cylinder and note down t1the m1 - t1 = M the weight of gas in Kilogramsmultiply the wt of gas in Kgs with 0.9403 ie. M x 0.9403 gives the total cubic meter of acetylene gas in cylindersNote: One gram of Acetyle gas measures 0.9403 litres at 27 degree centigrade and 760 mm of mercury pressure.
How do you calculate diameter of hydraulic cylinder to create ton pressure?
The equation Force = pressure x surface of the cylinder Electric power and torque and power you need to know what you want. After obtaining the surface area of ​​the circle diameter cylinder, the cylinder can get.
Is a hydraulic jack a hydraulic or pneumatic system?
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.
Can you use acetylene torch for silfoss?
no
How does the valve reservoir and pump function on a hydraulic cylinder jack?
the pump supply's the pressure, the resivoir supply's the fluid, the valve dirercts the fluid into the cylinder, to extend or retract the cylinder.
What state of matter is Acetylene in the cylinder under pressure?
Acetylene is different from most gasses in a tank. An acetylene tank is not hollow- it contains a porous material (think of a hard sponge) that is saturated with liquid acetone. When acetylene is pumped into the tank under pressure, it dissolves in the liquid. This is similar to how carbon dioxide dissolves in a soda (in a bottle or an) under pressure. While in the tank, it is mainly in a liquid.
Is it safe to use an acetylene tank that has not been used in about 10 years?
If there is pressure in the tank it may be possible to use it. If not I wouldn't recommend it. In the tank there are blocks of material and Acetone. These absorb the Acetylene allowing it to be charged to 300 PSI. If the Acetone (it is in liquid form) has leaked out the Acetylene could explode if the cylinder is recharged. Acetylene pressure is RED LINED at 35PSI.

Is acetylene a solid or gas?
Acetylene is a gas at standard temperature and pressure.
What colour are hoses for an acetylene cylinder?
red
Why Actelyne is called as DA cylinder?
Because it is also known as Dissolved Acetylene cylinder ...thus DA cylinder
What are the main consideration for the storage of compressed gas cylinder?
Go and check safety regulations, and do it thoroughly. Some cylinders must be stored under very strict conditions - acetylene cylinders, for instance, contain a fusible pressure release plug that may leak acetylene, and an acetylene-air mixture is highly explosive. Check the regs.
Acetylene gas should never be used at a pressure above?
15 psig. At pressures above that, acetylene can explode.
What has the greatest compressibility?
Hydrogen has a density of 0.08988 g/L. After that is helium (0.1786 g/L) .Liquefied GasesLiquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. They exist inside the cylinder in a liquid-vapour balance or equilibrium. Initially the cylinder is almost full of liquid, and gas fills the space above the liquid. As gas is removed from the cylinder, enough liquid evaporates to replace it, keeping the pressure in the cylinder constant. Anhydrous ammonia, chlorine, propane, nitrous oxide and carbon dioxide are examples of liquefied gases. Non-Liquefied GasesNon-liquefied gases are also known as compressed, pressurized or permanent gases. These gases do not become liquid when they are compressed at normal temperatures, even at very high pressures. Common examples of these are oxygen, nitrogen, helium and argon. Dissolved GasesAcetylene is the only common dissolved gas. Acetylene is chemically very unstable. Even at atmospheric pressure, acetylene gas can explode. Nevertheless, acetylene is routinely stored and used safely in cylinders at high pressures (up to 250 psig at 21°C). This is possible because acetylene cylinders are fully packed with an inert, porous filler. The filler is saturated with acetone or other suitable solvent. When acetylene gas is added to the cylinder, the gas dissolves in the acetone. Acetylene in solution is stable.
How many pounds per square inch in an acetylene tank?
In a new acetylene tank that is full there is 250 psi
What is full form of DA in gas cutting?
DA in Gas cutting mean Dissolved Acetylene
Is acetylene soluble in water?
Acetylene gas is usually dissolved in acetone, as in this condition it occupies a much smaller volume. [But your acetylene cylinders should be kept vertical.] And acetylene under quite modest pressure is very explosive just by itself.
