Foreword

This standard and ASTMF423-1995 "PTFE lined steel pipe fittings and flanges standard" non-equivalent. main Differences are as follows. --- ASTMF423-1995 standard fluorine plastic lining material is PTFE, expanded this standard similar to PTFE derived material; --- ASTMF423-1995 standard product size in inch dimension metric indicated, the standard is completely converted to the metric system; --- ASTMF423-1995 standard test methods including the standard test method for a direct reference to the GB/T 23711.1 ~ 23711.6-2009 Test Method "fluorine plastic lined pressure vessel" in. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Non-metallic chemical equipment Standardization Technical Committee (SAC/TC162) centralized.
