In 1957, the company began large-scale industrial activities and built pipeline networks around the world to supply large industrial areas. From 1963 the company began its first space activities. In 1986, Air Liquide expanded its business in the US by purchasing Big Three Industries from Texas and establishing additional offices in numerous countries in Europe and Asia. In 1995 the subsidiary Air Liquide Santé was founded, which focuses on the medical sector. This essentially includes medical gases and services.

In 2001 Air Liquide AGA took over Austria and the Messer Griesheim business in South Africa , Trinidad and Tobago , Canada, Egypt , Argentina and Brazil . The establishment of a joint venture with BOC in Japan ( Japan Air Gases , JAG) in 2003 served to strengthen the presence in the markets in the Far East.

In the following year, Messer Griesheim's business was also taken over in Germany, Great Britain and the USA. Air Liquide operates in over 70 countries worldwide. In 2007 Lurgi was taken over, which was previously a subsidiary of the Bochum GEA Group.
