Acetylene


What is Acetylene?

Acetylene (C2H2) is a colorless, highly flammable gas with a garlic-like odor.

Purchase High-pressure Acetylene

We offer compressed acetylene in various grades specific to different applications such as:
• A fuel gas (mixed with oxygen) for welding, cutting, brazing and soldering
• An essential gas for Atomic Absorption Spectrophotometry in laboratories

Industrial Applications

Fleet-Based Commercial Services; Retail (Automotive)
Acetylene is a crucial component in low-pressure carburizing, which creates strong, wear-resistant surface layers on steel parts.

Manufacturing & Metal Fabrication
Acetylene offers the hottest flame temperature of commercially available fuel gases—making it the ideal gas for oxy-fuel welding, cutting and brazing applications.

Laboratories
Air/acetylene and nitrous-oxide/acetylene are the gas mixtures used as a fuel source in Flame Atomic Absorption (FLAA).

Supply Modes
