The American Petroleum Institute (API) initiated the Piping Inspector Certification Program (PICP) to provide a continued high level of safety through the use of inspectors specialized in process piping; to improve management control of process unit inspection, repair, alteration and rerating; and to reduce the potential for inspection delays resulting from regulatory requirements. This program is based on API Standard 570, Piping Inspection Code: Inspection, Repair, Alteration, and Rerating of In-Service Piping Systems; and RP 574, Inspection of Piping, Tubing, Valves, and Fittings. The program promotes self-regulation and establishes a uniform program that assists state and local governments in process piping regulations.
