Product Details
Supplied as Dissolved Acetylene (DA) – dissolved in acetone under pressure in a range of specialized cylinders to ensure stability and to avoid detonation. GRADE: Industrial 98.5% (Min) and High Purity 99.6% (Min)
Processes that use acetylene
When burned with oxygen, acetylene produces the hottest flame of all the fuel gases (3200°C). Acetylene’s high level of reactivity makes it a very useful fuel gas for:
a) Welding
Oxy-acetylene welding is a cost-effective alternative to electric welding and a good alternative for remote locations that lack a reliable electrical supply. Acetylene is the only fuel gas that creates a flame hot enough to weld steel.
b) Cutting
Oxy-acetylene cutting offers better cut quality, higher cutting speed, faster cut initiation times and reduced oxygen use compared to other fuel gases.
c) Heat treatment
Oxy-acetylene is used for flame hardening of steel in-situ or for large components that do not fit in a furnace.
d) Coating
Oxy-acetylene used for flame spraying with wires or powder onto metals and ceramics, and non-stick mould coatings in metal casting.
Safety Information
Acetylene is an unstable gas that can suddenly decompose in the form of a deflagration or detonation. Therefore large volumes should not be stored in piping systems and vessels and care must be taken to prevent ignition sources, including accidental heating of pipes and electrostatic sparks.
Acetylene forms unstable and potentially explosive compounds with copper and silver and these materials should be excluded from acetylene piping systems. These piping systems need to be designed by specialists in that field. Flash-back or burn-back in acetylene hoses is a common hazard due to acetylene’s decomposition initiated by high temperatures at the welding or cutting torch head. Specialist hoses and regulators must be used.
