 Committee Scope

Welcome to the home page of the API Subcommittee on Inspection and Mechanical Integrity (SCIMI). The SCIMI develops industry standards that address inspection and mechanical integrity issues related to refining process equipment. Issues of particular interest to the SCIMI include: safe practices in the inspection of and repair of pressure vessels, aboveground storage tanks, and piping; equipment reliability; corrosion mechanisms; and reducing capital and maintenance costs. Each meeting of the subcommittee provides a forum for an information exchange on problems and opportunities where industry experts share experiences from operations around the world.

API 510 - Pressure Vessel Inspection Code
API 570 - Piping Inspection Code
RP 572 - Inspection of Pressure Vessels
RP 573 - Inspection of Fired Heaters and Boilers
RP 574 - Inspection of Piping System Components
