What are the main parts of the oxy-fuel torch?
The basic oxyacetylene torch comprises:
- torch body (or handle)
- two separate gas tubes (through the handle connected to the hoses)
- separate control valves.
- mixer chamber.
- flame tube.
- welding tip.
What does an oxyacetylene torch consist of?
The oxyacetylene flame is composed of two gases – oxygen and acetylene – and each cylinder is connected by a flexible tube connected to a flowmeter after a pressure reducer. The nozzle fitted to the tip of the oxyacetylene torch is characterised by the flow induced by its orifice.
What is the color of acetylene hose?
A blue color indicates the hose as suitable for use with oxygen, and a red hose is used for acetylene and other fuel gases.
What is the color coded of oxygen and acetylene?
Here are universal Color coding: oxygen cylinder is black and acetylene is maroon, hoses and regulators are color coded with oxygen as blue and acetylene as red. Here are a few safety tips to follow when using gas welding hoses.
What is the maximum working pressure of acetylene?
The working pressure of acetylene equipment is critical: Acetylene pressure must not exceed 0.62 bar (9psi) unless equipment has been specifically designed for it.
What is the ratio of oxygen to acetylene?
1.2:1
Natural Gas
| Fuel Gas | Maximum Flame Temperature °C | Oxygen to fuel gas Ratio (vol) |
|---|---|---|
| Acetylene | 3,160 | 1.2:1 |
| Propane | 2,828 | 4.3:1 |
| MAPP | 2,976 | 3.3:1 |
| Propylene | 2,896 | 3.7:1 |
What is the max pressure for acetylene?
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).
What color is the oxidizing flame?
blue color
An oxidizing flame is any flame that has an excess of oxygen present. A hissing noise, sharp candles, and a paler blue color easily identify the flame. This flame is cooler than a neutral flame because there is an excess of oxygen flowing though the combusting gasses.
What is green hose used for?
Green hose is used for carrying oxygen, and red hose is used for carrying acetylene. Bulk welding hoses are used to create custom hoses for welding applications.
What are red hoses used for?
In this case, the oxygen hose is invariably green, and the fuel hose is always red. The types of fuel used vary but the most commonly used are propane and acetylene. Natural gas, methylacetylene-propadiene (MAPP), and propylene are also used.
Why oxygen cylinder is black and white in colour?
The cylinder body colour of all medical gas cylinders will be changing to white. In the case of oxygen cylinders, the colour code for the shoulder of the cylinder is also white, which means the whole cylinder will be white for medical oxygen.
What is colour of o2 cylinder?
The oxygen cylinder colour code in India is a black body and white shoulder-coloured cylinder.
What is the standard color of acetylene tank?
Acetylene gas cylinder colour code is Claret Fire and explosion hazards are greater than LPG but it is slightly lighter than air and less likely to collect in ducts and drains.
What is the normal working pressure for acetylene?
How much acetylene is in a cylinder?
An acetylene cylinder is not precisely half-full when its pressure has dropped to 125 psi (half the pressure of a full cylinder). If the cylinder temperature is 700F (200C), the amount of acetylene remaining in the cylinder is slightly less than half the ”full” content.
What color is a rich flame?
A proper natural gas appliance flame colour is a vigorous blue colour flame with a lighter blue colour section within the middle of the flame. A small yellow colour tip may be present. A blue natural gas flame colour is indicative of proper combustion and minimal wasted gas.
