For oxyfuel cutting, heat treating and torch brazing applications

Acetylene is a flammable gas produced by the reaction of calcium carbide with water or as a by-product of ethylene production. Acetylene is dissolved in a solvent in a specially designed cylinder filled with a porous substance. Because the gas dissolves in matter, it is sometimes called "dissolved acetylene".

Acetylene's extremely high flame temperature (3100°C) makes it ideal for oxyacetylene cutting, heat treating and torch brazing. It is also used in organic synthesis in analytical laboratories and as a flame gas in analytical techniques such as atomic absorption (AA) spectroscopy. Sometimes it is used for chemically induced flower production.

Acetylene is available in different purity grades and concentrations to meet the specific requirements of different industries. It is a highly flammable gas and needs to be used in a safe manner for better and safe results. High-purity acetylene is also used in various laboratory techniques, such as atomic absorption spectroscopy. We have in-house laboratory equipment to check the level of purity and the various impurities present in it. The primary use of acetylene gas is the use of oxyacetylene flames in the metal cutting, welding and brazing industries. Due to its very high flame temperature, it is used where other fuel gases become less effective or ineffective.
