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.
The 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.
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.
Can you use acetylene torch for silfoss?
no
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.
What is the pressure of a full nitrogen cylinder?
...whatever pressure it was filled to...
What is Size difference between oxygen and acetylene cylinder?
Oxygen cylinders are typically larger and heavier than acetylene cylinders due to the higher pressure at which oxygen is stored. Oxygen cylinders may also contain more volume of gas compared to acetylene cylinders.
Why oxygen cylinder has greater size than acetylene cylinder?
Oxygen is stored at a much higher pressure than acetylene, which requires a larger cylinder to contain it safely. Additionally, oxygen is less dense than acetylene, resulting in the need for a larger volume to store the same amount of gas.
What colour are hoses for an acetylene cylinder?
red
Is acetylene a solid or gas?
Acetylene is a gas at room temperature and pressure. It is a colorless and highly flammable gas that is mainly used for oxyacetylene welding and cutting.
Why Actelyne is called as DA cylinder?
Because it is also known as Dissolved Acetylene cylinder ...thus DA cylinder
How many kgs of Calcium Carbide is used in a Acetylene cylinder?
A standard size Acetylene cylinder typically contains around 7 kg of Calcium Carbide, which is used to produce Acetylene gas through a chemical reaction. The amount of Calcium Carbide used can vary depending on the size and type of the cylinder.
What is the difference between an oxygen regulator and an acetylene regulator?
An oxygen regulator controls the flow of oxygen from a compressed gas cylinder to a torch or other equipment. An acetylene regulator performs the same function but is specifically designed to handle the characteristics of acetylene gas, which is highly flammable and requires a different pressure setting compared to oxygen.
What MC mean on acetylene regulator?
"MC" on an acetylene regulator usually refers to the type of cylinder it is designed to be used with. In this case, "MC" stands for "medium duty cylinder," which is a smaller sized acetylene cylinder compared to larger industrial cylinders. The regulator is specifically designed to fit and work with MC-sized acetylene cylinders.
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.
