Linde plc

Linde is a global multinational chemical company and the world's largest industrial gas supplier by market share and revenue. Founded by German scientist and engineer Carl von Linde in 1879 in Wiesbaden, Germany, the company is now headquartered in Woking, United Kingdom, and registered in Ireland as Linde plc. Linde plc was formed in 2018 through the merger of Linde AG and Praxair, which was founded in 1907 in the United States as Linde Air Products Company.

The company's primary business is the manufacturing and distribution of atmospheric gases, including oxygen, nitrogen, argon, rare gases, and process gases, including carbon dioxide, helium, hydrogen, ammonia, electronic gases, specialty gases, and acetylene. Linde's products are used in the healthcare, petroleum refining, manufacturing, food, beverage carbonation, fiber-optics, steel making, aerospace, material handling equipment (MHE), chemicals, electronics and water treatment industries.

Linde is ranked 463rd on the Fortune Global 500 and 187th on the Forbes Global 2000.

The company has two principal business areas: gas (industrial gases and medical gases), and engineering, procurement, and construction.

In the industrial gas area, the company uses the brand names Linde, AGA, BOC, TIG, Mox-Linde Gases, Afrox, Sigas and PanGas. HiQ is used as an identifier for high purity and premium specialty gases across all of these business brand names.

In the medical gas area, the company uses the brand names Linde Gas Therapeutics, AGA Medical, INO Therapeutics, Linde Homecare, and Farmadomo.

Linde Gas supplies industrial gases, medical gases, specialty gases, refrigerants and other chemicals. Depending on the gas and the quantity required, these may be supplied in portable high-pressure gas cylinders, in liquefied form by road tanker, from on-site gas generators or in gaseous form via pipeline to large customers. This division has four operating segments, Western Europe, the Americas, Asia & Eastern Europe, and South Pacific & Africa. These segments are subdivided into eight Regional Business Units (RBUs). The Gases Division also includes the two Global Business Units (GBUs) – Healthcare (medical gases) and Tonnage (on-site) – and the two Business Areas (BAs) – Merchant & Packaged Gases (liquefied and cylinder gases) and Electronics (electronic gases).

The product range includes hydrogen, acetylene, carbon monoxide, carbon dioxide, shielding gases for welding applications, noble gases and specialty gases, oxygen, nitrogen, and argon, all of which are manufactured in Linde's air separation plants.
