Patent number: 6365227Abstract: A corrosion resistant gas cylinder and gas delivery system includes an electroless nickel-phosphorous layer overlying the inner surface of a steel alloy cylinder. The nickel-phosphorous layer has a thickness of at least about 20 micrometers and a porosity of no greater than about 0.1%. The electroless nickel-phosphorous layer has a phosphorous content of at least about 10% by weight and a surface roughness of no greater than about 5 micrometers. Prior to introducing liquefied gas into the gas cylinder, a cleaning process is carried out using a two-step baking process to clean the surface of the nickel-phosphorus layer. The nickel-phosphorous layer substantially reduces the contamination of liquefied corrosive gasses stored in the gas cylinder by metal from the steel wall surface underlying the nickel-phosphorous layer.Type: GrantFiled: March 22, 2001Date of Patent: April 2, 2002Assignees: L'Air Liquide, Societe Anonyme pour l'Etude et, l 'Exploitation des Procedes Claude of France, American Air Liquide Inc.Inventors: Alan D. Zdunek, Eugene A. Kernerman, William Korzeniowski
