Several highly publicized refinery piping failures around injection points have made apparent the need for more detailed inspection requirements in these areas. This need was addressed by the American Petroleum Institute (API) with the first edition of the API 570 Piping Inspection Code. This paper discusses implementation of an inspection program that complies with API 570 injection point inspections and improves the overall reliability of injection systems. Four case histories are presented to illustrate the benefits of increased inspection efforts and to provide experiences to help improve existing inspection programs.
