About Linde plc
Linde plc is a globally leading company for industrial gases and engineering. The portfolio comprises industrial, medical and specialty gases (HiQ), electronic gases and gas supply in all delivery forms: from cylinders and bundles to bulk and liquid gases, on-site plants and pipeline supply. The offering is complemented by specialty equipment (REDLINE and BASELINE pressure regulators, gas panels), cryogenic air separation plants and VPSA oxygen plants from a few tonnes to thousands of tonnes per day, Hot Oxygen technology for syngas production as well as industrial services such as inerting, pigging, leak detection, pressure testing and reactor turnaround solutions (IN2ERT, NiCool/CATCOOL). Further fields are well stimulation with N2 and CO2 pumping, cryogenic food freezing and chilling, gas management and automation (ACCURA, DIGIGAS, SECCURA) as well as Engineering, Procurement and Construction via Linde Engineering. The gases serve, among other things, semiconductor manufacturing, medical oxygen supply and hydrogen production. The headquarters is located in Woking, United Kingdom; supplies are delivered to more than 80 countries. Revenue in 2025 amounted to 34 billion US dollars.

Gases and Process Technologies
Oxygen
Used for medical technology, steel production, gasification and as hot oxygen (>3,600 °F) in HOT technology to boost syngas production.
Nitrogen
Inert gas for inerting, blanketing, pigging, cooling and cryogenic freezing and chilling processes.
Argon
Shielding gas for welding applications and base gas for rare gas production.
Hydrogen
Feedstock for clean energies and industrial processes; Linde has been active in the hydrogen field for over 50 years.
Carbon dioxide
Used for food freezing (pumping), concrete curing and well stimulation.
Helium
Rare gas for electronic and research applications.
Acetylene
Fuel gas for welding and cutting processes.
Carbon monoxide
Chemical raw gas for petrochemical processes.
Nitrous oxide
Medical and food gas, also with electrically heated regulators (V 106P/1) to prevent dry ice formation.
