What else can I help you with?
Acetylene gas should never be used at a pressure above?
15 psig. At pressures above that, acetylene can explode.
Which of the fuels used in the oxy-fuel process becomes unstable if stored or used above 15 per square inch?
Oxy-fuel cutting uses acetylene and oxygen to preheat metal to red hot and then uses pure oxygen to burn away the preheated metal. Acetylene, which is used in the oxy-fuel process becomes extremely dangerous if it is used at pressures above 15 pounds per square inch.
What is the regulator adjustment pressure for oxygen and acetylene?
The recommended regulator adjustment pressure for oxygen is typically between 20-50 psi, while for acetylene it is usually between 5-15 psi. It is important to consult the specific manufacturer's guidelines for the correct pressure settings for each gas.
Why is acetylene rather than butane gas used for welding?
Acetylene is used for welding because it burns hotter than butane, allowing for faster and more efficient welding. Additionally, acetylene produces a reducing flame, which helps prevent oxidation of the metal being welded. This makes it particularly well-suited for welding ferrous metals like steel.
What oxygen and acetylene pressures are used when cutting 12.7mm sheet with a positive pressure torch?
For cutting 12.7mm sheet with a positive pressure torch, oxygen pressure should typically be set around 30-40 PSI, while acetylene pressure should be set around 5-10 PSI. These pressures may need to be adjusted based on the specific torch and cutting conditions. Always refer to the manufacturer's guidelines for the most accurate pressure recommendations.
Acetylene gas should never be used at a pressure above?
15 psig. At pressures above that, acetylene can explode.
How many pounds per square inch in an acetylene tank?
In a new acetylene tank that is full there is 250 psi
When welding with a 3 tip what should the oxygen and acetylene be set at?
If you set your tanks to about 5 psi and 5psi, you should not have to change the pressure, instead simply adjust the knobs on the torch to give more of each gas. If this still is a problem, try 7-9 psi for each. NEVER NEVER NEVER go above 12 for acetylene, it is unstable at 15, best to not get close...
What gases can be crammed into small spaces with ease?
All of them, with caveat that some gases will auto ignite if compressed too much. (The biggest malefactor here is acetylene; if it's compressed to over 15 psi, it becomes highly unstable.)
Why gases are kept in air tight cylinders?
So they'll stay in the air tight gas cylinders. Some gases are expensive and others are dangerous (some are both), and you don't want them leaking out. These cylinders are not only air tight, they're very pressure resistant. Most gases are shipped at between 2000 and 5000 psi, and the cylinder has to be made to withstand that much pressure. Acetylene is shipped at 250 psi because it's unstable at higher pressures, but acetylene cylinders are also capable of withstanding 2500 psi.
Which of the fuels used in the oxy-fuel process becomes unstable if stored or used above 15 per square inch?
Oxy-fuel cutting uses acetylene and oxygen to preheat metal to red hot and then uses pure oxygen to burn away the preheated metal. Acetylene, which is used in the oxy-fuel process becomes extremely dangerous if it is used at pressures above 15 pounds per square inch.
What is the regulator adjustment pressure for oxygen and acetylene?
The recommended regulator adjustment pressure for oxygen is typically between 20-50 psi, while for acetylene it is usually between 5-15 psi. It is important to consult the specific manufacturer's guidelines for the correct pressure settings for each gas.
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 causes air to become more unstable?
what is the only way air can become unstable
What is the pressure of a full acetylene cylinder?
The pressure of a full acetylene cylinder can vary depending on the size of the cylinder and the temperature. Acetylene is typically stored in cylinders at a pressure of around 250 psi (pounds per square inch) at room temperature. However, this pressure can increase as the temperature rises, so it is important to follow safety guidelines and regulations when handling acetylene cylinders.
Why is acetylene rather than butane gas used for welding?
Acetylene is used for welding because it burns hotter than butane, allowing for faster and more efficient welding. Additionally, acetylene produces a reducing flame, which helps prevent oxidation of the metal being welded. This makes it particularly well-suited for welding ferrous metals like steel.
How does a person become radioactive?
By becoming unstable
