Select a step where Air Liquide intervenes in your value chain.

Inert gas blanketing

We supply industrial gases for clean melting processes and casting applications. Air Liquide’s patented Expanding Gas Air Liquide (EGAL) process uses liquid cryogenics, i.e. argon or nitrogen, to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen and water. This SPAL technology allows manufacturers to produce castings with fewer defects, enhanced mechanical properties and lower rejects.

Air Liquide offers SPAL, Air Liquide’s technology family of inert blanketing processes. These patented processes include EGAL, Surface Backfilling Air Liquide (SBAL) and Vapor Ring Air Liquide (VRAL).
