Acetylene Portapak (Refill)

Product Details

Acetylene is a highly flammable colourless gas of distinct odour. The high solubility of acetylene in acetone (300:1 by volume at 1 100 kPa) enables it to be supplied dissolved in acetone. Acetylene cylinders are filled with porous material which carries the acetone. The recommended regulator W003034

 

APPLICATIONS:

 

Acetylene is used as a fuel gas for oxy-acetylene welding, cutting, general localised heating, flame hardening, flame cleaning to remove rust from steel, spalling concrete, and other processes requiring a high temperature flame. Steel, stainless steel, aluminium and wrought iron are recommended for use with acetylene.

 

FEATURES & BENEFITS:

 

Acetylene is the best and most versatile fuel gas for welding, straightening, bending, forming, hardening, cutting or tempering. It is the hottest flame temperature when compared to MAPP gas, propylene and propane and natural gas. Specially purified instrument grade acetylene which has impurities removed is used in atomic absorption, analytical instrumentation and navigational beacons. A low flame moisture content makes it a good choice for many critical heating processes. It also requires the least amount of oxygen to ensure complete combustion.

 

HAZARDS:

An asphyxiant with anaesthetic properties

Forms an explosive mixture with air

Can form explosive acetylides with unalloyed copper, silver, mercury, brass containing more than 66% copper, and brazing materials containing copper and silver

Can spontaneously decompose within equipment and pipework under certain flow, temperature and pressure condition

 

Oxygen Portapak (Refill)

Product Details

Oxygen as a gas is slightly heavier than air, but will dispense fairly rapidly in a well-ventilated area. However, it can remain for long periods in cavities, trenches, pits and vessels. Oxygen will also remain for considerable periods in clothing or similar porous materials. The recommended regulator W003031

 

APPLICATIONS:

 

In combination with a fuel gas such as acetylene, hydrogen or LPG, it is used in welding, cutting, brazing, hardening, scarfing, flame cleaning and heating. Oxygen is used in the manufacture of steel, glass, ethylene oxide, methanol, acrolein, titanium dioxide, vinyl acetate and synthesis gas. It can be utilised in any chemical reaction where air is used to give faster reaction time and higher yields. Also suitable for laboratories, metal analysis and medical treatment

 

FEATURES & BENEFITS:

 

Oxygen is most commonly combined with a fuel gas for cutting, welding, brazing and glass blowing as it greatly enhances combustion efficiency.  It is colourless, odourless and tasteless.  It is slightly heavier than air but will dispense fairly rapidly in a well-ventilated area.  Copper, brass and high-quality stainless steel are the most common materials used with oxygen.  They should be fully degreased as oil and grease can cause ignition.  Most lubricants are therefore not compatible with oxygen.

 

HAZARDS:

 

 

High pressure compressed gas

Vigorously supports combustion of many materials which will not normally burn in air

Any heat source hotter than 50°C must be regarded as a possible igniter of fires in the presence of gaseous oxygen or oxygen-rich atmospheres
