Profile: Linde North America LLC is a supplier of industrial, specialty & medical gases and engineering products & services. We are an ISO 9001:2000 certified company. We offer a wide range of designs, solutions, products and services (including compressed & liquefied gases, via tanker, rail, cylinder or pipeline). We also specialize in engineering, development, construction and operation of turnkey industrial plants. We supply various industrial gases including argon, carbon dioxide, helium, hydrogen, and oxygen gases. Argon is a colorless, odorless, tasteless and nontoxic gas. Argon, along with helium, neon, krypton, xenon and radon is also known as a rare gas. Applications for argon often utilize its inert properties for protection against the oxidizing effect of air. Argon is widely used as a blanketing or shielding gas in metallurgy and arc welding & cutting. Argon is also used to fill incandescent and fluorescent lamps. Oxygen is a colorless, odorless and tasteless gas that supports life & combustion. All elements, except rare gases, react with oxygen, over a wide range of temperatures, to form oxides. The major uses of oxygen are based on its combustion-sustaining, oxidizing and life-supporting attributes. Whether used directly or to enrich combustion air, oxygen is widely used with fuel gases in furnaces, smelters, kilns, welding and metal cutting. Oxygen is used in chemical production as a raw material and in pulp manufacturing as a bleaching agent.
