About Praxair, Inc.

Praxair, the largest North American industrial gas supplier, produces and sells atmospheric gases (oxygen, nitrogen, argon, and rare gases), as well as process and specialty gases (CO2, helium, and hydrogen), for the chemicals, food and beverage, semiconductor, and healthcare industries worldwide. It serves a score of industries in some 50 countries. Its Praxair Surface Technologies unit supplies high-temperature and corrosion-resistant metallic, ceramic, and powder coatings, mainly to the aircraft, plastics, and primary metals markets. Praxair merged with German gases company Linde in 2018 in a deal worth $80 million. The combined company operates under the Linde name.

Change in Company Type

The size of the company that resulted from the Praxair and Linde merger should enable it to compete in the worldwide industrial gases business. The combined company, which took the Linde name, would have revenue of $28 billion, around two million customers, and 80,000 employees. Not that they were small before the merger. Linde and Praxair ranked 2 and 3 in the industrial gas business behind Air Liquide. Now, Linde should be bigger than Air Liquide. 

Each company sold operations to satisfy regulators concerned about antitrust issues. Praxair sold most of  its European businesses and some of its industrial gases business in India, while Linde sold most of its Americas business and some of its South Korean industrial gases business. Each company sold assets its Asia.


Praxair operates in North America, Europe, South America, and Asia. In addition, Praxair operates its worldwide surface technologies business through Praxair Surface Technologies.

Praxair’s business segments are gas supply and management; industrial services; oil and gas services; and surface coatings.

Gas supply and management offers cylinders and liquid containers; bulk and microbulk delivery; pipeline; on-site production; mobile nitrogen pumping service; and small on-site production. 

Industrial services consists of refineries and chemical plants; pipeline services; terminals and pipeline leak location; dry ice blasting; CO2 services and applications; and specialty services. 

Oil and gas provides services in enhanced oil recovery, energized fluid fracking, and well injection services. It is also a supplier of nitrogen and carbon dioxide. 

Surface coatings’ processes include  brushed, dipped, flowed or sprayed slurries; diffusion; laser processing; plating; thermal spray; and vapor deposition.

Geographic Reach

Praxair has facilities in Rio de Janeiro, Brazil; Shanghai, China; and Madrid. It also has operations in Tonawanda, New York and Burr Ridge, Illinois in the US; in Monterrey, Mexico; and Bangalore, India. Research and development for industrial gases is principally conducted at the Tonawanda, Burr Ridge, Shanghai, and Bangalore sites.

It also has operations in Korea and Thailand, with smaller operations in Taiwan and the Middle East.

Sales and Marketing

Praxair distributes its products through networks of hundreds of production plants, pipeline complexes, distribution centers and delivery vehicles. Major pipeline complexes are in the US, Brazil, Spain, and Germany.


Praxair merged with Linde, based in Germany, to form the biggest industrial gas company. The merger was in response to Air Liquide's takeover of Airgas. The combined company, operating under the Linde name, expects the merger to deliver $1 billion in cost reductions while expanding the company's global footprint. While Linde and Praxair sold off units to comply with regulators' antitrust concerns, the company has operations around the world.

Company Background

Praxair and Linde both go back to the origins of the industrial gas industry in the 19th century. 

Karl von Linde, a professor of mechanical engineering at the College of Technology in Munich, Germany, in the late 1800s, created the cryogenic air liquefier. Von Linde built his first oxygen-production plant in 1902 and a nitrogen plant in 1904, and in the first decade of the 20th century, he built a number of air-separation plants throughout Europe.

By 1907 von Linde founded Linde Air Products in Cleveland as the US subsidiary of his German company. Linde Air Products joined rival Union Carbide in 1911 in experimenting with the production of acetylene; it became a unit of Union Carbide in 1917 during World War I.

In the 1990s, the gases business spun out of Union Carbide and became Praxair.
