Codes and Standards Related to Total Corrosion Life Control in Chemical Plants

摘要

The codes and standards that have implications for corrosion engineers are looked over. However most of Japanese standards are made for keeping qualities of materials at production and fabrication. To maintain aged equipments in chemical plants, post construction standards that provides the procedures of fitness for service are strongly required. And very limited qualified corrosion resistant data based on fully standardized test of various charges of materials is available. At the corrodion design and corrosion life control, more reliable and statistically analyzed data including long term trends is also needed. Only the contributions and efforts of corrosion engineers can construct practical engineering bases and standards of corrosion services in industry for themselves.
