Dissolved Acetylene
Derived by the Chemical reaction of water on Calcium Carbide; then purified and dissolved in acetone for storage in cylinders.
Very flammable (in pure form), dangerous fire risk, burns with intense hot flame; explosive limits in air 2.5 - 80%. Forms explosive compounds with silver, mercury and copper, which should be excluded from contact with acetylene in transmission systems. Copper alloys may be used with caution. Piping should be electrically bonded and grounded.
Application and use
- cutting
- flame heating
- flame gouging
- gas welding. The only fuel gas which can be used to weld steel
- flame hardening. An oxy-acetylene flame can be used where the hardened surface of carbon steel components is either in situ as a remedial process or on components too large to fit in a furnace
- flame cleaning. A wide oxy-acetylene flame is held very close to a steel surface to be cleaned
- flame straightening where the precise and efficient flame properties are used to remove distortion in plate material
- thermal spraying of various metals and ceramics. The material to be sprayed is fed through the flame
- spot-heating applications
- brazing
- texturing
- profile-cutting
- branding wooden pallets
- wood-ageing
- glass and metal castings
- mould release and other anti-stick applications
- the only fuel gas recommended for use in underground working conditions
