초록

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 b...

[ What is claimed is:] [1.]1. A high-pressure steel gas cylinder comprising:a cylinder wall having an inner surface,an electroless nickel-phosphorus layer overlying the inner surface having a thickness of at least about 20 micrometers and a porosity of no greater than about 0.1%; and a surface roughness of no greater than about 5 micrometers,wherein the electroless nickel-phosphorus layer is subjected to an acid wash and a hot deionized water wash, followed by a first bake under continuous nitrogen flow and a second bake under vacuum pressure.
