Description
The dissolved acetylene is intended for gas-flame processing of metals, food of acetylene lighting installations, laboratory works and other purposes.

• for welding and cutting of metals,

• as a source of very bright, this world in independent lamps where it turns out reaction of carbide of calcium and water,

• in production of explosives,

• for receiving acetic acid, ethyl alcohol, solvents, plastics, rubber, aromatic hydrocarbons.

Acetylene, burning down in acid, gives very hot flame (to 3150 °C) therefore it is widely used for welding and cutting of refractory metals. Gas-flame processing of responsible knots of machine-building designs is made only by means of acetylene which provides the highest productivity and quality of process of welding.

Acetylene is widely used in organic synthesis of various substances — acetic aldehyde and acetic acid, synthetic rubbers (isoprene and hloroprenovy), polyvinylchloride and other polymers.

Cylinders with the dissolved acetylene transport all means of transport according to the rules existing on this type of transport.
