What size oxy acetylene hose do I need?
Hose Size: The I.D. (internal diameter) of hose used for most welding and cutting purposes ranges from 3/16-in. to 3/8-in (4.8 to 9.6 mm). When the length of hose required between regulator and torch is not more than 25 ft., 3/16- in. hose is adequate for all welding, and for most cutting and heating.
Are oxygen and acetylene hoses interchangeable?
Fuel gas hose and oxygen hose shall be easily distinguishable from each other. The contrast may be made by different colors or by surface characteristics readily distinguishable by the sense of touch. Oxygen and fuel gas hoses shall not be interchangeable.
What are the different grades of oxygen and acetylene hoses?
There are two grades of welding hose for acetylene. Grade R hose is the most popular and cheapest. Grade R is only for acetylene.
What color hose is used for acetylene?
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 minimum bursting pressure for a new oxy acetylene hose?
Hose shall have a minimum bursting pressure of 1,000 psig (6.8 MPa). The assembled manifold including leads shall be tested and proven gas-tight at a pressure of 300 psig (2.04 MPa). The fluid used for testing oxygen manifolds shall be oil-free and not combustible.
What color is the oxygen hose on an oxy acetylene outfit?
Hoses between the torch and the gas regulators should be colour-coded; in the UK: red for acetylene, and blue for oxygen. Fittings on the oxygen hose have right-hand threads; while those on the acetylene hose have left-hand threads. The primary function of a gas regulator is to control gas pressure.
Can oxygen and acetylene tanks be stored together?
Oxygen cylinders shall not be stored near highly combustible material, especially oil and grease; or near reserve stocks of carbide and acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire; or in an acetylene generator compartment.
Can I use an oxy acetylene torch with propane?
Oxy Propane/Propylene Torch Whilst a standard Oxy Acetylene Torch can be used for Oxy Propane/Propylene, it’s far from ideal. Propane & Propylene are slower burning gases. Propane & Propylene also travel through the system as a vapour, not a gas, not actually turning into a gas until they meet air.
Can you use propane in acetylene hose?
You WILL need to change your Acetylene Regulator to a Propane type (including for Propylene). You WILL need to change your Acetylene Hose to a Propane Hose (including for Propylene). You will need to check the label on your Flash Arrestor, if it says “Fuel”, it’s OK to use with Propane & Propylene.
How far apart should oxygen and acetylene be stored?
It specifies that there is a minimum distance between oxygen and acetylene cylinders which is required. Class 2.1 flammable gases (acetylene) and Class 2.2 non-flammable oxidising gases (oxygen) must be stored at least 3 metres apart (more information on the classification of gases can be found here).
What color hose is used for the oxygen on a cutting torch?
Oxygen hose is usually green with right-hand threaded connections; red hose with left-hand threaded connections (indicated by a groove- about the nut) is used with any fuel gas. They are designed to prevent improper connections between the regulators and the torch.
Can I store oxygen and acetylene cylinders together?
Risks and hazards of acetylene and oxygen gases Acetylene cylinders and oxygen cylinders both have their own unique risks and hazards, and MUST NEVER be stored together as they can react dangerously with one another.
