MECHANICAL INTEGRITY - API

API has taken an active role in the creation and propagation of MI information and materials. API committees create Standards and RPs that address MI, largely in the areas of inspection and repair of pressure vessels, aboveground storage tanks, equipment reliability, corrosion, mechanics, and reducing capital and maintenance costs.

API Standard 682

This standard is referenced normatively in API 610. It is applicable to both new and retrofitted pumps and to pumps other than API 610 pumps (e.g. ASME B73.1, ASME B73.2, and API 676 pumps). This standard might also be referenced by other machinery standards such as other pumps, compressors, and agitators. Users are cautioned that this standard is
