The report describes a research program conducted to determine the facts of natural gas contaminants on corrosion of cylinders used to contain compressed natural gases (CNG). Work reported includes results of a survey of gas transmission and distribution companies to determine compositions of representative natural gases and to learn what composition limits are imposed by gas company standards and the U.S. Department of Transportation (DOT). Manufacturers were contacted to determine materials and manufacturing procedures used in the production of CNG cylinders, and a literature search was conducted to determine reported effects of natural gas contaminants on the corrosion and stress corrosion cracking susceptibility of gas cylinders and cylinder materials. Destructive analyses of eight used CNG cylinders made of steel and one made of an aluminum alloy revealed that none of them had experienced significant corrosion and no evidence of stress corrosion cracking was found.
