A Detailed Guide to Oxy-fuel (Oxyacetylene) Welding ...
Gas welding and cutting. (1) Transporting, moving, and storing compressed gas cylinders. (a) You must ensure that valve protection caps are in place and secured. (b) When cylinders are hoisted, you must secure them on a cradle, slingboard, or pallet. You must not hoist or transport them by means of magnets or choker slings.

Bulk gas storage has a minimum separation of 3 meters. Flashbacks are commonly caused by a reverse flow of oxygen into the fuel gas hose (or fuel into the oxygen hose), producing an explosive mixture within the hose. The flame can then burn back through the torch, into the hose and may even reach the regulator and the cylinder.
Oxy-Fuel Gas Cutting Torch Safety Reminders
Both oxygen and fuel gases are filled in the cylinder at high pressure. These gases cannot use at this high pressure for welding works, so a pressure regulator is used between the flow. It supplies oxygen at a pressure of about 70 – 130 Kn/m2 and gas at 7 – 103 Kn/m2 to the welding torch.

What is the ratio of oxygen and acetylene in gas cutting?
Torches that do not mix fuel with oxygen (combining, instead, atmospheric air) are not considered oxy-fuel torches and can typically be identified by a single tank (oxy-fuel cutting requires two isolated supplies, fuel and oxygen). Most metals cannot be melted with a single-tank torch.
Gas-Cutting: Process, Techniques and Advantages | Welding
Nov 26, 2012 · Cutting with Nitrogen, however, uses a technique known as fusion cutting. With this process, the laser melts the material and the high pressure Nitrogen ejects the material through the cut. Because Nitrogen is an inert gas, it does not react with the molten metal and therefore your cut is much cooler than if it was cut with Oxygen.
MAPP gas - Wikipedia
The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy-acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.

Oxygen And Acetylene Use And Safety - ia
Generally acetylene is used with oxygen to provide the preheat flame but other gases can be used: propane for example or hydrogen which is used for underwater work because of its compressibility. Apart from the torch, the equipment is similar to that for gas welding.

OXYGEN GAS CYLINDER . Oxygen cylinder is drawn from a piece of high strength steel plate and is available in common sizes of: o 244 cu ft (for industrial plants); o 122 cu ft; o 80 cu ft Oxygen is stored within cylinders at a pressure of 2200 psi when filled @70°F and is capable of retaining a pressure of almost twice the fill pressure.

May 07, 2012 · I cut a discarded 12" dia oxygen cylinder in half to make a gas forge out of the bottom half. I used a 4" angle grinder, and ran it around and around the cylinder, getting deeper and deeper (can you feel the suspense?), until it broke in half (or if you prefer, two). The top half now hangs as a gong in my yard.
What is the difference between oxygen and acetylene gas cylinder?
When it happens, close the oxygen cylinder valve first, then close the valve of the acetylene cylinder. Never resume welding until you figure out the cause of the backfire and fix it. For flashback or explosion, isolate the valves of both the cylinder types first. Immediately turn off the oxygen first then turn off the acetylene.
Oxygen Cutting - an overview | ScienceDirect Topics
Hydrogen gas should never be stored near oxygen, chlorine, or other oxidizing gases. Thesematerials must be separated by at least 20 feet or an appropriate gas cylinder cabinet must beused. Cylinders must be located at least 25 feet from open flames, ordinary electrical equipment, and/orany ignition source.

Is it safe to cut acetylene gas cylinders?
Dec 31, 1998 · Section 1926.350(a)(10) requires that oxygen cylinders that are in storage be separated from fuel-gas cylinders and combustible materials. It specifies that the cylinders either be separated by a minimum of 20 feet or have a non-combustible fire wall (with a fire resistance rating of one half hour) at least five feet high.
